[pyronavi (pyronavi-linux-kernel-bugs)]

I get no sound via the speakers of my Lenovo Legion 7i laptop, which alsamixer tells me is using a Realtek ALC287.

I have tried various Linux distros and kernel combinations, including Ubuntu 16.04, 18.04, and 20.04, with both the default and mainline kernels (5.7.x & 5.8.x), and Manjaro with 5.6.x, 5.7.x and 5.8.x kernels.

In each case, I made sure to disable Auto-Mute in alsamixer, and turn all volume levels to maximum. In all cases, I get no sounds from the speakers (running speaker-test, playing music, etc.). I *am* able to get sound via headphones and HDMI (though I believe HDMI is via a different sound card).

Also, I can see that there is some kind of sound activity occurring when I look at pavucontrol (the reddish-orange bar that indicates a sound is playing), but there is no actual sound produced from the speakers.

My alsa-info.sh results (from Manjaro on 5.6.15) are here:

http://alsa-project.org/db/?f=ba86fe76a9d9cf1cced56600edf82eb206a36a72

I am happy to run the script again (or any other tool) from a different distro/kernel combination, please just let me know what would be helpful.

In order to provide better information, I have run alsa-info.sh from Ubuntu 20.04 running the latest mainline kernel 5.7.9-050709-generic. I have also updated the "Kernel Version" field in this bug report to reflect this.

[pyronavi (pyronavi-linux-kernel-bugs)]

I also tried with kernel 5.8.0-050800rc5-generic. Same result, no sound via speakers.

[cam (cam-linux-kernel-bugs)]

Can confirm here with Kubuntu 20.04 with kernel 5.4.0-40-generic and kernel 5.7.14... Sound works through head phones (using either bluetooth or a analog 3.5 mm cable). I did notice that playback via bluetooth stopped once... After putting the laptop to sleep then waking it back up, audio via bluetooth resumed.

I do not know if I am able to get audio via HDMI, I'm unsure how to use that setting (or is an external HDMI monitor needed for that?).

I have the exact same issue on Linux version 5.4.0-47-generic (buildd@lcy01-amd64-014) (gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2)), with Lenovo Legion 7 81YT. I tried the same things as everybody else and could not get these speakers to work. I am a bit confused because some specs I found online for the the Legion 7 mention ALC 3306 -https://psref.lenovo.com/syspool/Sys/PDF/Legion/Lenovo_Legion_7_15IMHg05/Lenovo_Legion_7_15IMHg05_Spec.pdf (could not find any driver related to it) Vs ALC 287 identified by alsamixer.

My issues are also present on Legion 7i (Legion 7-15IMH05 Type 81YT).

Here is my alsa-info: http://alsa-project.org/db/?f=f74d2b20683de3bc0daab8c4740f34a66955ba70

A notable thing is that i *DID* have speaker audio for a couple of weeks (headphones have always worked), until it suddenly stopped working again. My guess is that there might have been regression due to some package being updated but I could not find any meaningful culprit.

I can paste the hidden BIOS HD audio settings for this configuration if that's of any use.

Do you have any details for the time period that you did have sound? Was it a fresh install of Ubuntu 20.04.1? Did you allow internet updates during install? If you still have the ISO you used, I'd also like to confirm the hash of the file. If we can reproduce it, we'll be a lot closer to a solution.

[pyronavi (pyronavi-linux-kernel-bugs)]

Also, regarding the advanced BIOS settings, there are several sound modes you switch the laptop into.

I tried a few but didn't get anything to work. I'm not very knowledgeable in this area though.

Accessing advanced BIOS is documented here:

[cam (cam-linux-kernel-bugs)]

For convenience, here's how to navigate to the audio settings under the advanced BIOS settings:
Advanced -> PCH-IO -> HD Audio Configuration

I going to attach pictures showing the top level Audio menu. There's quite a bit more settings under the sub-menus though.

It's worth mentioning that in my experience that many settings available under the advance BIOS settings do not seem to work. I haven't tried any of the audio settings yet (and there are quite a few), but in general many settings probably only apply to certain models of laptop aside from the Legion 7i. Presumably at least some of the audio settings should work though.

About how long have you had your Legion? I've had mine since August 6th IIRC, and I've always had this problem. Could help narrow down the window.

Could this be possibly related to a BIOS update?

I got mine in the beginning of August. Updated immediately to 2.02 BIOS.

I had already prepared for not having sound as I had read the Arch Wiki page, and was really struck with a surprise as one day after playing with merely the ubuntu sound settings (fiddling with system sound volume) the speakers suddenly started working. I did not make any notes of the occasion as I assumed there might have been a recent kernel or some other package update, and did not expect any regressions to occur. But they did a couple of weeks later and that's when I found this ticket for ALC287.

What makes tracking this down a bit trickier than just booting with earlier kernel packages is that I have fiddled with both alsa and pulse on the system (e.g. tried different kernel module options for snd-hda-intel) so my working state was never a vanilla install with some updates. I will nevertheless try to get back to a working configuration with some kernel and report back.

[cam (cam-linux-kernel-bugs)]

I immediately upgraded to 2.02 as well... But tried reverting to the previous version (2.01 probably?) to test something unrelated. That didn't fix my issues.

Anyway, might be worth looking at /var/log/dpkg.log* to see what had been installed/updated around that time frame. I've skimmed through and so far the only thing that stands out are some pulse audio updates on July 23rd. So unless you don't update frequently, that's probably not it.

I'm having the same issue on a Lenovo Legion 7-15IMHg05. I just got it this week (22nd september) and installed Arch Linux on it straight away. I tried fiddling with alsamixer and pavucontrol settings, no change. I tried different kernel packages (linux 5.8.10, linux-lts 5.4.66, linux-xanmod 5.8.10/11), no dice. I did not update the BIOS yet and the current version is "E9CN32WW(V2.00)", so this probably rules out a BIOS regression.

My alsa-info: http://alsa-project.org/db/?f=60beb004225ca38c49bb6a1495e6cd713a1a4f1e

I did not test the laptop with Windows yet, but I will try to do this soon.

[pyronavi (pyronavi-linux-kernel-bugs)]

Perhaps there is a way to force ALSA to recognize the card as an ALC3306. As Fab mentioned, the specs do seem to indicate that as the sound device.

[cam (cam-linux-kernel-bugs)]

Did you find this in the documentation? I haven't found any references
to ALC3306 on my system

Doing a quick search for ALC3306, the only references that come up are
for the Lenovo Legion 7 and the Yoga Slim 7.  The ALC3306 seems to be
pretty uncommon and pretty new.

Doing a bit of research, sounds like audio works on the Yoga Slim 7.
Possibly a red herring..?

My mistake. I must have seen "Legion 7" and mistaken it for the 7i.

Also, I have just sent an email to the members of the ALSA team. Hopefully someone will reply soon.

Tested now, it works fine on Windows. I also updated the bios to E9CN58WW(V4.03), still doesn't work on Linux.

[cam (cam-linux-kernel-bugs)]

I think the 7 and 7i are the same. In the case of the Legion 5/5i, the i
differentiates between the AMD and Intel versions. However, I believe
there's still no plans to make an AMD version of the Legion 7.

My point was that sound seems to work on the Yoga 7 under Linux, which
also has the ALC3306 so maybe it's not related to the ALC3306 codec.

Well, the bug has been assigned to Jaroslav Kysela even if it's still not critical (are we too few?). Did you try to contact him for debugging?
Here(https://unix.stackexchange.com/questions/611530/how-can-i-get-my-unsupported-sound-card-to-work-with-alsa) and here (https://www.alsa-project.org/wiki/Help_To_Debug_Intel_HDA) there are some hints to start debugging the codec. I'd do it myself but I haven't bought it (yet? :D)

[gorghino (gorghino-linux-kernel-bugs)]

Plus, are you sure that the Legion 7 15IMHg05 works with ALC287? PSREF from Lenovo website reports ALC3306 that is actually missing in sound/pci/hda/patch_realtek.c

[cam (cam-linux-kernel-bugs)]

I came across this today:
https://github.com/alsa-project/alsa-lib/issues/76

The last posts suggests that "amplifier chips for the integrated speakers" might be in use here which need to potentially initialized. That could explain why 3.5mm and bluetooth audio work: They don't need any such initialization.

[gorghino (gorghino-linux-kernel-bugs)]

I left Ubuntu for ArcoLinux and sound works. I installed their LTS Linux kernel and Intel microcode and sound came out of the left speaker only. Then, Lenovo pushed a firmware update this morning and sound works in both speakers. I don't know why an Arch fresh install works but the "easy windows conversion Linux OS" doesn't.

[perex (perex-linux-kernel-bugs)]

Guys, don't spam me (e-mail).

I don't have the detailed information about your hardware and it seems that the hardware vendors are using the amplifier chips for the integrated speakers on recent hardware which must be initialized, too. The linux support depends on the BIOS initialization (if any) at the moment.

The HDA codec setup in first comments for Legion 7i looks fine, but Realtek use many hidden (undocumented) registers to set some configuration parameters and may be some other chips (amplifiers) behind.

Contact Lenovo, if you can, for help (BIOS - Linux support). They are supporting more the non-gaming hardware in Linux (ThinkPad/ThinkStation series).

Also, adding David Ober from Lenovo to Cc.

I downloaded the latest ISO and running it from USB with the latest BIOS update, sound still doesn't work at all for me. But maybe that's because their live image doesn't have the latest LTS kernel, firmware, microcode, etc?

With the latest BIOS, sound still doesn't for me under Kubuntu 20.10.

[cam (cam-linux-kernel-bugs)]

Seems the latest BIOS (E9CN60WW/v4.05) broke sound completely. I couldn't even get audio over my bluetooth speaker. Reverting back fixed it for me, however.

I can confirm that if you "install" or dual boot Arcolinux that sound will work. I just did a reinstall not less than an hour ago. Sound doesn't work from the live USB but will work if you install Arcolinux with the LTS kernel. However, I'm using the Yoga Duet 7i.

I'm using the Yoga Duet 7i and I don't know what the difference is between the LTS Kernel with Arch and Ubuntu's LTS version - but devs should be able to tell us pretty quickly.

Same thing here on my 2 yo Legion Y730. Sound-wise everything worked fine for 18 month when i was running ubuntu 18.10, then still good on 20.04.1 for a few weeks and about three weeks ago internal speakers stopped working (but sound works fine on headphones or bluetooth).
My kernel is 5.4.0-58 and sound chip Realtek ALC298.
Bios version : 8XCN24WW(V1.07)

I have had the same problem since I got this laptop in late November. It is a Yoga 7i. I am on Ubuntu 20.10 with kernel 5.8.0.29. I have tried 5.9.10 and 5.9.12 mainline kernels.

Everything appears "normal" except the sound just isn't coming out of the speakers. It registers the card, shows up in pavucontrol as expected. The sound output indicator even shows as if audio is playing.

I have dabbled with development of kernel modules in the past, but know nothing about audio codecs. Let me know if you need any help from someone with the hardware and kernel experience.

It sounds like you may already know the culprit, but that it is not fixable without some specs.

Joining the party. Just got Lenovo Legion 7i 15 w/ Realtek ALC287, speakers do not work. Very glad I found this thread -- I have tried so many things at this point.

Yay so glad I found this after all the stuff I tried before (documented here: https://forums.fedoraforum.org/showthread.php?325363-Lenovo-Thinkbook-no-sound-over-speakers-with-Fedora-33/page1).

Mine is a Thinkbook 13s with a Tiger Lake chip and High Definition (HD) Audio, Realtek® ALC3306 codec according to the spec sheet (https://psref.lenovo.com/syspool/Sys/PDF/ThinkBook/ThinkBook_13s_G2_ITL/ThinkBook_13s_G2_ITL_Spec.PDF). Same problem the built in speakers have no sound output even though the headphones and HDMI output sound just fine.

I even tried the latest vanilla kernel: 5.11.0-0.rc2.20210108gitf5e6c330254a.119.vanilla.1.fc33.x86_64 but still no sound from the speakers.

Lastest LTS Kernel 5.4.89 breaks ACL287 on Lenovo Yoga Duet 7i. Until now, the only distro and kernel I've found to work with this model is Arch Linux, ArcoLinux to be specific, and 5.4.88-1-lts. I'm assuming this should also work for Legion 7i too.

I think it was mentioned earlier that the sound chip uses some bits to
enable the amplifier section. Bluetooth and the headphone jack are
unaffected. You would have to probe the chip to find what bits have been
turned on in Windows to make the same changes in the linux driver.

I saw those fixes from Hui back when I was trying out different kernel versions in Dec. I feel he would ultimately fix this issue in time. But time has gone on a bit too long. So I wanted to see if it was more of lacking sample hardware that might be holding it back.

I see that the change is probably just a couple lines in this file: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/sound/pci/hda/patch_realtek.c?h=v5.10.13.

I just need to know the pins/values to try. There are Thinkpad C940 quirks and the HP ALC287 quirk. This one is different, but they serve as a good template. Now, where do I get those pins? My system is dual boot, so I can go into Windows. Is there a tool I can run to enumerate possible pins/values? Or do I reuse ones I am seeing here with subtle logic guesses?

[mysubstmp (mysubstmp-linux-kernel-bugs)]

On my system, the Lenovo Yoga Duet 7i, volume doesn't work out of the box. I've not found any arch systems that have sound working out of the box. You must use earlier an earlier LTS kernel "5.4.88-1-lts". Upgrading to 5.4.89-1-lts and newer will break sound again. I'm not sure why this is such a big deal now since I've mentioned this. Devs could just use whatever works in 5.4.88 LTS and add it to newer kernels. Or tell us how to do it and I'll try myself.

[cam (cam-linux-kernel-bugs)]

Vanilla 5.4.88 doesn't resolve the issue, at least not for me on Kubuntu
20.10. Earlier 5.4 kernels that I've tested in the past have not fixed
the issue.

I'm not really familiar with Arch... but if I can find the Arch patchset
for 5.4.88, I'll try it out and report back.

Then there must be some other differences with sound for the Legion 7i and the Yoga Duet 7i. Try removing sof-firmware and make sure it isn't muted in pavucontrol

[cam (cam-linux-kernel-bugs)]

I used the arch patches and kernel config to build the exact equivalent
of 5.4.88-1-lts. This did not fix anything as expected as the 3 Arch
patches were all unrelated to audio/alsa so this is not a surprise (one
was to the documentation). Of course, I checked pavucontrol, alsamixer,
etc. Made sure nothing was muted, played with the volumes in case it
would "unstick" anything.

Either there are some differences between Yoga Duet 7i and the Lenovo
Legion 7i and/or there's some important userspace differences. I suspect
the former. But even if the Duet 7i has its sound issues addressed
first, this could potentially go a long way towards helping to figure
out what the Legion 7i needs. Can someone with a Duet confirm that
vanilla 5.4.88 works and 5.4.89 does not? If so, bisecting should narrow
down the issue.

There needs to be a push by the linux community and possible litigation to force companies to provide documentation

[cam (cam-linux-kernel-bugs)]

Alas, I doubt litigation is on the table.

I also absolutely would not have purchased this laptop had I known sound
support would have been an issue in Linux (or at least returned it
within the first 30 days had I known 6 months later this would still be
ongoing). I received mine back in August... Now I'm starting to eye new
laptops already because I don't have any sound. However, now I'm also
concerned that comparatively spec'ed laptops may also have sound issues
potentially due to amplifier sound chips that could result in the same
problem.

At some point in the near future, I may resort to purchasing new laptops
and returning them within 30 days if there are any issues under Linux,
because I simply can't assume they'll be addressed.

Lenovo not wanting to put any developer time into drivers doesn't
necessarily mean they're refusing documentation. Perhaps a code bounty
could work? I'd be willing to donate to that cause.

Do try to install Archlinux and use the kernel https://gitlab.com/manfromva/manfromva/-/tree/master/Kernels

I have a Duet 7i with the same sound system and I currently have sound. It didn't work for me on endeavoros but works with Arcolinux and Garuda so far.

Do you mind posting the results of alsa-info?
I could not access the kernel link. Is it a private project?

[darnellkeithj (darnellkeithj-linux-kernel-bugs)]

Try now. I had it on private for some reason. That is the official kernel and headers from arch Linux - arcolinux to be exact. I added them on gitlab because it's difficult to get older arch kernels. It Can be used with any Arch distro but I just ran into a bug where my speakers won't work after I connect Bluetooth headphones with Garuda Linux. I'm installing RebornOS Linux now and will try there. Worked just fine with Arcolinux and several other Arch distros.

RebornOS didn't work for me but it may be to the lxqt version I installed. Manjaro works fine though.

Yes, install fedora 33 and update everything. Then at least the bottom speakers will work.

if your using a legion 7 (that's what I have). My understanding is that there is no kernel support (I could be very wrong about this so anyone feel free to correct me). I have used a few distros on my laptop and I use arco linux (its not debian I know) on the latest zen kernel. I still don't have sound out the speakers, but headphones work. So if you are fine with using headphones, any distro will work

You typically have 30 days to return a brand new laptop so keep that in
mind.

If you do end up returning it, please be clear in your communication
that it's due to the lack of working audio in Linux.  :)

Thank you! The third answer here: https://askubuntu.com/questions/1253498/no-sound-on-headphones-with-sof-hda-dsp-audio-on-ubuntu-and-variants to add the line

options snd-hda-intel model=auto

to

/etc/modprobe.d/alsa-base.conf

seems to have fixed it, so perhaps this is not the same bug after all (and I get to keep my laptop!).

PS this is after applying the fix, let me know if you need me to unfix it and do the same.

[zanto98 (zanto98-linux-kernel-bugs)]

I'm running Arch (5.11.5-arch1-1) on a Lenovo Yoga 7i and I managed to get audio to work with Realtek ALC287 under certain circumstances.

It works only after I suspend to RAM, and it disappears within around 7 seconds of not playing any audio (playing it muted is enough to keep it alive). I also have to start the playback within 7 seconds of resuming from suspend, or alternatively keep it running when suspending.

It does not work after suspending to disk, suspending to idle, or rebooting, but hybrid-sleep works. I did not have to blacklist or otherwise configure related kernel modules in /etc/modprobe.d, but I did have to enable S3 sleep by manipulating the DSDT table following https://wiki.archlinux.org/index.php/DSDT. Now I did not really know what I was doing because the patch in the article did not apply to the table on my system; I only changed a line reading "Name (SS3, Zero)" into "Name (SS3, One)", but it worked.

Incidentally my brightness keys are only recognized when suspending to RAM or disk, so it seems like there is some necessary initialization going on that are only correctly carried out during certain sleep states.

Here is a dmesg log, where I did the following:
start playing some audio (no sound)
# echo s2idle > /sys/power/mem_sleep
# echo mem > /sys/power/state
waking up (no sound)
# echo deep > /sys/power/mem_sleep
# echo mem > /sys/power/state
waking up (audio starts playing)
pausing and resuming after 7 seconds (no sound)

I don't have any sound on my Lenovo Yoga 7i 15" with Fedora 33.
Tried Suse, Ubuntu and Mint as well and it is same result.

[florianseidel2204 (florianseidel2204-linux-kernel-bugs)]

i would like to attach myself to the problem.

New Lenovo Legion 7, no Sound on Manjaro or Ubuntu, not on Live-USB, not on installed OS. Headphones working perfectly, Speakers giving no sound at all.
Has there been any kind of solution by now?

I am still in my 30-days trial-period, am very happy with this machine, but do all my development for work on linux. if possible, i would love to avoid sending it back and buy another machine.

Did anyone else with the problem try my "workaround" from comment #97? It's actually not too bad, I just suspend whenever I need audio from my speakers and play some music muted in the background in a loop to keep it alive in case playback is interrupted. Not perfect but usable.

[cam (cam-linux-kernel-bugs)]

This workaround doesn't work with the Legion 7i, unfortunately.

But you do get S3 sleep when suspending or managed to activate it?

I have the same model and it worked with the same kernel on Arch. Which OS did you try?
Unfortunately kernel 5.11.12 broke my S3 sleep again and my previous fix doesn't work, completely breaking speaker audio for me again.

I am running Ubuntu 20.04.2LTS, and I rolled back to kernel version 5.10.04 recently from 5.11, as the 5.11.12 made my microphone un-usable.

In this case S3 sleep is deactivated. You could try to follow the section "Manual method" in https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_X1_Yoga_(Gen_3)#Enabling_S3_(with_BIOS_version_1.33_and_after), but instead of the patch it says there just replace
   Name (SS3, Zero)
with
   Name (SS3, One)
and in a line at the top like
   DefinitionBlock ("", "DSDT", 2, "LENOVO", "CB-01 ", 0x00000002)
you need to increment the last number (change it to 0x00000003 in this case). This is what it took for me to get S3 sleep working, and then right after suspending the speakers work if playback is started within a magical window of a few seconds.

I have no idea why or how but internal speakers are working again on my Legion y730. Since i posted here back in december i didn't work on that issue and i realized they were working again only this morning (as my headphones were almost always plugged in) so it might have happened before.

Only things i did this past few weeks that might have helped are : upgrade nvidia drivers, install winetricks, upgrade kernel to 5.8.0-50 generic

If anyone needs more info on my system, i'm happy to help.

Like others my headphones via 1/8 jack seem to work fine but not a lick of sound from the built in speakers. Lots of trying suggestions noted throughout this thread to no avail. Playing sound while selected on speakers it looks like there is activity just no sound of course.

hdaJackRetask seems to not work at all on my unit and hangs quite often where you have to force quit. I was hopeful trying to use it might find some workaround. Anyway not sure if that says anything about the issue.

The problem is to enable the S3 :
Try : cat /sys/power/mem_sleep
You will have : "S2idle [deep]"
Try : sudo dmesg |grep ACPI|grep supports
You will have : [ 0.195933] ACPI: (supports S0 S3 S4 S5)

If not, you will check how to enable S3 :
==== ENABLE S3 ====
We have to patch the DSDT table
1) Install iasl :
sudo apt-get install acpica-tools cpio

2) make acpi directory
mkdir acpi

3) Get a dump of ACPI DSDT table:
sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.aml

4) Decompile the dump, which will generate a .dsl source based on the .aml ACPI machine language dump :
iasl -d dsdt.aml

5) Make the patch file

Does your 14ITL05 even have 5 speakers like the 15ITL05? There are thre above the keyboard and 2 below the palm rest. Do you really know that it applies to it? On the 15ITL05 only the bass speakers above the keyboard are not working.

[DavidLenovoFr (davidlenovofr-linux-kernel-bugs)]

Hi,
What is your model please ?

For the Lenovo Support, and for the technical information, the Yoga 7i 14" & 15" are the same (the 15" just have 1 USB more), both have Dolby Atmos with 2 Speakers.

I Think I have make a mistake with the Yoga Slim 7 14ITL05 & 15ITL05 with 3 speakers ("3 haut-parleurs (3 x 2W), Dolby Atmos").
IdeaPad 5 15ITL05 have the same reference, very strange ... with 2 speakers to like the 15ITL5.

This code 14ITL05 or 15ITL05 don't have any result on Lenovo website, but I have see it in my BIOS dump. So I have suppose that is just another reference for the same computer.

So sorry, visibly is not the same, and this number is for 2 different computers :(

My post is for the Yoga 7i 14ITL5 and 15ITL5, but it seem we have the same, or similar BIOS, so the process to enable the S3 can be the same or really similar.

The problem, for me, is to enable the S3, to have sound in any speaker.
If you don't have sound in all speaker, is more a drivers problem, in my point of view. So this is not a solution for you, sorry.
Or a mixing problem ?

Hi,
Sorry, in step #2 after makdir acpi, go in the directory : cd acpi.
You can do it in another directory.
Yes you have to enter in the acpi directory before the step 3.

No speaker working (but headphone, hdmi... are working).

I did not try kernel 5.11.5 (My Pop Os is in 5.11.0 but I remember trying Ubuntu 21.04 and there was no sound also).

Just tried with kernel 5.11.5... No luck...

How ACL3306 not recognise, can we find some spec or information about it? Seems Realtek codec information is nowhere to be found... :(

My unit is the Yoga 7-14ITL5 laptop (Ideapad) - Machine Type Model: 82BH0006US

It is only a 2 speaker system, right and left.

From a Windows 10 install on my device it is the ALC287. I see no reference in Windows of ALC3306.

Lasty, sadly, none of the suggestions, be it using Arch or Ubuntu, have worked for myself to get sound from the speakers at any point.

Could you recheck, please :
cat /sys/power/mem_sleep

sudo dmesg |grep ACPI|grep supports

Do you have try, to play a long sound with VLC, y choose PulseAudio Server if it is available, on another session I just have sof-hda-dsp Speaker + Headphone (it work on both). If your change the sound output, stop and restart the sound.
Let the sound playing and put in sleep, put the computer on, and the sound work. It lagging for me at the beginning, and after few seconds it is ok.

You have ALC287 or ALC3306 ? You seem to have ALC3306, no ?
Not sure Ubuntu is work well for it.

I think your problem is to enable S3.
It is probably not the same patch for you with you Lenovo Think Book 13s Gen 2. The patch is for Yoga 7i 14" and 15"

The user Wave could you help me more I think, my knowledge is limited.

Sorry :( to don't mention you.
Thanks a lot :), effectively you see the problem firstly and you try to put all of us in the right way.
To be honest my knowledge is to limited to patch me alone. I had need the patch "key in hand", found after (put in my tutorial).
I think other people, need the patch "key in hand", with more simple tutorial.

I think your have lot of skill, and me (and probably other) just want simple solution (and can't do hard modification).

I'm not sure to understand, your are the writer of the tutorial : https://wiki.archlinux.org/title/Lenovo_Yoga_7i ?

I think we are lot of people, to don't have lot of knowledge, and need very simple procedure. And for me I see lot of people very skilled, like you, to be documentation not enough easy for us.
This is why I make this tutorial, with almost all commands.
For example the patch for the Yoga 7i (on Arch Wiki), don't have the beginning of the file :
--- dsdt.dsl~ 2018-04-26 09:35:29.501055509 -0600
+++ dsdt.dsl 2018-04-26 09:36:23.769729028 -0600
So it can't work as is.
I had to take time to understand, and find why it don't work, I never do it before.

Thanks another time :)

Don't worry, I didn't mean to criticize you at all :)
Quite the contrary, I know that my instructions were very terse (in that I did not duplicate instructions that are available elsewhere, which would be the wrong thing to do on the archwiki anyway), and I'm happy that you went through it, figured it out, and published your findings in an accessible way. You even cited my tutorial from archwiki so everything is perfect.

Thanks also for pointing out that the patch does not quite work with the patch command linked in the article; it works if you put the patch into a file like acpi.patch and then run
patch dsdt.dsl acpi.patch
(specifying both the file to be patched as well as the patch file). But I'll change that in the article. Nice that you figured it out though!

Sure thanks, here is my outputs! :)
cat /sys/power/mem_sleep
[s2idle] deep

sudo dmesg |grep ACPI|grep supports
[ 0.242864] ACPI: (supports S0 S3 S4 S5)

VLC -> played long song, plugged headphone (sound on headphone works), changing output to speaker, no sound (note that sound meter show sound in preference, but sounds do not output to the speaker).

Put computer into sleep while playing. After resume, still no sound in speaker...

I have ALC3306. The only "not Ubuntu" I tried was Calculate Linux (Gentoo). I use PopOs, tried Ubuntu 21.04 also.

Only informations I found on the web always point back here.

Some infos: https://afterhourscoding.wordpress.com/tag/backlight/
And the kernel part: https://github.com/torvalds/linux/blob/master/sound/pci/hda/patch_realtek.c

At this point I fear it's becoming little too hard for me, but I can still try to do something.

If I understand well this sentence 'According to Jaroslav Kysela Lenovo is using amplifier chips for the integrated speakers on recent...

Sorry,
I write to quickly.
So you have to found the line : GRUB_CMDLINE_LINUX_DEFAULT=
Replace or complete with :
GRUB_CMDLINE_LINUX_DEFAULT="mem_sleep_default=deep"

Put GRUB_EARLY_INITRD_LINUX_CUSTOM="/boot/acpi_override"
ERROR in my precedent post juste 1x" not acpi_override"" -> acpi_override", sorry.
This line probably don't exist.

After you have to regenerate grub :
10) Regenerate the GRUB configuration :
sudo update-grub

recheck the step 11, it could, it would be erase by Grub :
> 11) Tell GRUB to load the new DSDT table on boot in its configuration file
> usually located in /boot/grub/grub.cfg. Find the relevant GRUB menu entry
> and add the new image /boot/acpi_override to the initrd lines for the
> images
> that you want the s3 sleep to work in :

sudo nano /boot/grub/grub.cfg
or
sudo gedit /boot/grub/grub.cfg
(it could be easier to find initrd part)
replace in the kernel part initrd in the part menuentry (and all submenu) of the file /boot/grub/grub.cfg :

initrd /boot/initrd.img-5.11.5-051105-generic
> BECOME :
initrd /boot/acpi_override /boot/initrd.img-5.11.5-051105-generic

5.11.5-051105 is for the 5.11.5 kernel, you will have other number, you just have to do it for 5.11 kernels.

Ok :)
Thanks for your work, and your wiki page, it's very great to have speakers :)

Your sure your have to hibernate ?
For me in S2 or S3 hibernate (suspend to disk) is the same.
But sleeping : suspend to ram, is not the same in S2 and S3.

For me I boot, and I make a sleep (suspend to ram) to enable speaker and brightness hotkeys.

Your tutorial (Wave) have a script with : rtcwake -m mem -s 1 that it is : suspend to memory.

@Vincent Morel : could you try sleep (suspend to ram) (not to disk) ?

You're right, my bad, sorry. Hibernating takes too much time to wake up, I think that's the reason why it doesn't activate sound (my brightness keys do work after suspend to disk/hibernate). Should do
systemctl suspend
instead, this should trigger S3 sleep.

I tried hibernate and suspend. Hibernate do not allow me to wake the computer, I have to reboot.
Suspend works great but no sound at all.

For the question regarding DSDT, no, I did not have to patch anything to have "deep" activated.
And my Brightness key work out of the box (as all the special keys, volume, mute, mic mute, plane...).

Ok, thanks.
As you say, you have the ACL3306 not ALC287, Is it different ?
Do you have try with Windows ? And shutdown totally Windows, I have read a partial shutdown could lock equipment. But I don't know more.

Okay, well you do have a different sound card after all, so it might be better to open a separate bug report, and maybe also one for the hibernation issue.

I am also going to join the new thread.
Despite the alsa-info showing ALC287, I just realized that the Legion 7i 15IMH05 has the Realtek® ALC3306 codec (https://psref.lenovo.com/syspool/Sys/PDF/Legion/Lenovo_Legion_7_15IMH05/Lenovo_Legion_7_15IMH05_Spec.pdf).
I have not seen any mention at the kernel source about the ALC3306.

Just confirming that I was able to follow the tutorial by @wave to get my speakers working. S3 sleep enabled without a hitch. I have the Lenovo Yoga 7i 14ITL5. The only issue I ran into was with the login script, but I'm personally OK with that for now (appears I have a permissions issue). I'm currently running Manjaro 21.0.5. I simply have to play some audio, suspend, then wake. Audio then plays through the speakers immediately after waking, even before I unlock the session.
Just sharing my experience. Thanks to all who have contributed to the progress being made on this issue!

I tried the Arch wiki tutorial on Fedora, Fedora Rawhide, and at least one Ubuntu based distro, but to no avail. It worked only on an Arch based distro for me. I used the latest Manjaro Gnome with the default LTS kernel.

No luck here with making the sleep working.

Anyone know if someone is in contact with the manufacturer?

Hi, for you and all people without S3, could you try :
cat /sys/power/mem_sleep

sudo dmesg |grep ACPI|grep supports

And find kernel: ACPI: DSDT 0x...(remove by me) ...(remove by me) v02 LENOVO CB-01 00000003 INTL ...)
Do you have 00000002 or 00000003 ?
I think sudo dmesg |grep ACPI|grep DSDT will work
or just sudo dmesg |grep DSDT

Thanks

I contact them, for Lenovo it's not specified it is an Linux laptop, so it is not a problem.
The problem is reported by the person answer me, but we don't have tracking or any-else.

You can check an alternative BIOS, the problem seem to be created by a deactivation of the S3 in the BIOS. We have a limited bios, but people have found in another model, it's just a switch to enable in the dump. www.bios-mods.com can modify your dump to enable this.

Yes. Just on Arch (and I've tried several distro bases). It's workable. I just have to boot, play audio, suspend, then wake to get speakers working.

I can't believe it's been almost a year without this problem being solved. I tried Ubuntu, PopOs, Fedora, Debian, they all had the same audio problem. I guess I'll just have to get used to headphones now.

Hello, what is your computer model ?
The problem is not link to the ALC287, just to enable the S3 in computer.

This method worked pretty well for me (Lenovo Yoga 7i) with kernal 5.8.0-53-generic #60,
After update to 5.8.0-55 the S3 is not visible.

when I'm grepping for ACPI I see that the overwriting of the acpi DST table is done very early in the dmesg log, whereas in 0.55 it's done later, maybe that's an hint.

My model is lenovo legion 7i 15IMHg05. I'm using Pop OS for now so It does not use grub boatloader. I don't know if I can change the kernel init. Can you explain how to "to enable the S3 in computer." ?

Also, your solution seems to work on yoga models, I didn't see anyone with legion model saying it worked for them. Here are my outputs:

Are you sure the Legion is ALC287 ?

Well, that's even more complicated. so even the system is reporting the wrong driver ?

Can you guide me to a good solution for this ? I'm just tired of searching the whole web for ACL287 so it turns out to be ACL3306

[jason349 (jason349-linux-kernel-bugs)]

I believe that Lenovo sells 2 versions of the Legion. We bought a bunch for the company I work at and it is the ALC287. We ended up giving those to Windows users and bought ones that had Ubuntu pre-installed.

The behaviour of the audio suggests that there maybe an i/o line controlling the amp to the speakers, imho.

So maybe that's caused by the same changes incorporated in my 5.8.0.53-#60 to 5.8.0.55-#62 which happened between 1. June 21 and 11. June 21 breaking the fix.
So hopefully that will disappear onecmore with the next update

It works! the script works! on my Samsung Galaxy book pro 360, Unbuntu 21.04

[dantahoua (dantahoua-linux-kernel-bugs)]

I tried the script on PopOs 21.04 on my Lenovo 13s Gen 2 (ALC3306) but sadly it did not work. The script even removed the working input mic and now I just have dummy output in place of the regular output... :( But it seems we are on the good way! :)

[mysubstmp (mysubstmp-linux-kernel-bugs)]

I also tried the script on Ubuntu 20.04 on Legion 7i 15IMH05 and got the same result. It removed the working input mic and just a dummy output showed up.
Niclas, how did you generate that script? It looks like it had a dos format.

[niclas (niclas-linux-kernel-bugs)]

First off, im sorry for the very minimal post with that pastebin. Very bad form and I have no other excuse then being emerged in another project and I had my head up my butt.

So. I have the new Samsung Galaxy Book Pro LTE that just came out and I found this post:

https://forum.manjaro.org/t/howto-set-up-the-audio-card-in-samsung-galaxy-book/37090

I tried that script by chance and it works. Although, it has 361 lines (!) and I havent started to disect it yet. Im not sure all of those is needed, when I run it I can hear that it first starts up the left speaker, then the right. I will take that on later.

But that post also helps out for those that doesnt know how to make the changes permanent. As for you who found that this works for your specific device, you will have noticed that just closing the browser with youtube or killing vlc/aplay or whatever makes the sound disappear again. Running the script once more, will make it work again and so on.

Im still in my other project so im not going to do any work on this one for now for a while yet, but if someone else does, please share here in the thread.

//Niclas

[niclas (niclas-linux-kernel-bugs)]

I forgot, if you do just blindly use that script and decide to also add the systemd services it will actually work and be permanent after a reboot.

How it work ? Anyone have to open a ticket, to signal it ?
It the same for the 5.11.5 work and after 5.11.6 and more stop working

Thanks :)

On Lenovo Yoga 7i ?

Could you try and report :
cat /sys/power/mem_sleep

sudo dmesg |grep ACPI|grep supports

Thanks in advance

Your S3 is already activated : you have [deep] and ACPI : S3 :-)

It is suspend to ram, not to disk, is it that your have test ?

Like Vincent Morel say Are you sure the Legion is ALC287 ?

I have the same dmesg as you, but ehdaudio0D0 not hdaudioC1D0 and 2 line more :

You don't have to patch acpi DST table for this model ?
I'm looking for a permanent solution, now the grub-update erase the solution, and we have to edit the grub.cfg, after each update.

I think it is normal, this patch is for Lenovo Yoga 7i, and it depend on the hardware, so don't have the same :(.

The S3 problem can be resolve by a BIOS option, Lenovo put a locked BIOS so we can't. But if Dell is better on this you could try to find an option S3, or energy, ACPI, it disable for Windows compatibility.

I find this : https://downloads.dell.com/manuals/all-products/esuprt_laptop/esuprt_laptop_latitude/latitude-14-9420-2-in-1-laptop_reference-guide_en-us.pdf
Not sure to understand :(

You have try this 5.11.5 kernel, to be sure, it is not a kernel bug ?
We don't know the 5.13.x working, @Dre, do you have more information of you version ?

Could you try and report :
cat /sys/power/mem_sleep

sudo dmesg |grep ACPI|grep supports

It's easy to port this patch to Dell, but that's not the point: iasl fails even without applying the patch, which should not happen ;-) But I think I have to ask the iasl people why this fails.

It's a similar issue on Dell. S3 in BIOS is enabled, but:

$ cat /sys/power/mem_sleep
[s2idle]
$ sudo dmesg |grep ACPI|grep supports
[ 0.201665] ACPI: (supports S0 S4 S5)

Kernel 5.11 is even worse because it doesn't even recognize the sound card. With 5.13rc5 at least the headphone jack and the microphone is working. But basically I think it's either this problem or the problem reported in #213159...

The fix broke each time I updated the system (which updated the kernel). I simply ran through the steps and it restored the fix. I'm currently on 5.13.0-1-MANJARO and have deep sleep again after applying the fix.

[cam (cam-linux-kernel-bugs)]

It seems someone was able to make progress on a similar issue via PCIE passthrough of their laptop's soundcard:
https://bugzilla.kernel.org/show_bug.cgi?id=207423
https://bbs.archlinux.org/viewtopic.php?id=256009

Yesterday, I tried getting this to work on my 2020 Lenovo Legion 7i. The Windows VM seems to see the device in the device manager (and I see the right numeric PCIE ID under Windows), but beyond that Windows doesn't seem to recognize the device properly (although it does know it's a sound card at least but it isn't able to use it even with the proper drivers installed).

This was my very first experience with the IOMMU stuff. Maybe someone else would have more luck?

Before even attempting this, I set some option in the BIOS (under advanced mode): "Enable VTIO", which I assumed was for VT-d. I haven't confirmed whether or not this was needed, but mentioning it just in case.

Example of soundcard working in win10 VM via passthrough. Comments include steps.

Screenshot of example Windows 10 VM working with RealTek sound card passthrough. The exclamation point for the "Intel(R) Smart Sound Technology" (Intel(R) SST) OED device is a red herring and is fine.

Here are my notes to get this physical device running under a Windows 10 VM:

You need to force the device expanded above to use the RealTek driver. I was able to force it by *extracting* rather than installing the sound driver from the Lenovo site. Selecting update driver on the sound device listed under "Sound, video and game controllers", and from there I did:
"Browse my computer for drivers"
"Let me pick from a list of available drivers on my computer"
"Have Disk"
Browse to: C:\Drivers\Audio\201211706.15485923\Realtek\Codec_8975.1\HDXLVSST.inf
Press Ok
You should see "Realtek High Definition Audio(SST)" as an option. It's the only option for me)
Next
Yes
Restart the VM when prompted

[cam (cam-linux-kernel-bugs)]

As my previous posts/attachments imply, I managed to get the sound card working in a Windows 10 VM with PCIE passthrough and I've been able to trace the events.

I was able to get this process working by following these threads,
As well as reading various wikis:
https://bugzilla.kernel.org/show_bug.cgi?id=207423
https://bbs.archlinux.org/viewtopic.php?id=256009

If anyone is interested in trying this and needs help, I can probably help you get going into the right direction at the very least.

The issue I had previously is that I would say I had to be more "aggressive" in getting Windows to use the correct driver. You'll know it's working when you're able to play audio in your VM and hear it through the laptop's speakers.

Might also be helpful if someone does this on a Yoga Slim. Perhaps there are some differences in the verbs that must be sent out to the sound card.

From here I guess what needs to be done is figure out what from these traces is needed and maybe try to write a script that that calls hda-verb to send the same verbs to the sound card under Linux (don't forget to re-enable the card for use under Linux again if you had PCIE passthrough setup!).

I'll sign up with the ALSA mailing list and give an update on this issue since I suspect there's likely enough here for progress to be made.

Correct, everytime the grub is updated I need to reconfigure the fix, which works in my case for 5.8.0-53 but not for 5.8.0-55. For the 55 kernel I simply can't enable S3.

To be more correct, I tried it oncemore and the result is, that with the 55 kernel after applying the patch you can now see:

/sys/firmware/acpi/tables/DSDT1
/sys/firmware/acpi/tables/DSDT2

the DSDT1 holds the original values whereas the DSDT2 holds the new values.

Might be relevant: https://bugzilla.kernel.org/show_bug.cgi?id=212643. This was a bug introduced by some commit in the ACPI subsystem, but it is fixed in recent versions of the kernel (somewhere around 5.13). Basically it would depend on what kind of distribution you are on, and whether their kernel is recent enough to have incorporated the fix.

Yeah it can happen that the DSDT table is basically broken. If you are willing to invest time and patience, you can dig through the ACPI spec https://uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf and google the error messages to figure out what you need to do to fix it.

That sounds very promising, thank you very much! I don't currently have time but I'm definitely intrigued to look into this and hopefully finally develop a real fix.

HUGE progress!

I reached out to Connor McAdams, the auth of QemuHDADump, about some issues I was having with QemuHDADump, and he directed me to https://github.com/ryanprescott/realtek-verb-tools

This is a pair of scripts meant to work with the JCS fork of Qemu (which is just qemu patched for more output to stdout including CORB info for Intel HDA). That repo for that is here: https://github.com/jcs/qemu

Last night I had found this repo, and I had simply tried to apply a patch from the JCS repo... It didn't work. The fields in the output were all zeros. Don't do that. Just build from the JCS repo directly.

Running qemu binary from the JCS qemu, I was able to extract verbs from the the JCS Qemu output and apply them to the laptop using the realtek-verb-tools scripts.

Applying these verbs initially didn't seem to work... So I tried playing music while applying them and you will get momentary blips of sound (specifically I heard blips of the track I was playing and not random noise)! What's most likely happening is that we need to extract a subset of these verbs for initialization and that some of the other verbs are stopping the sound (perhaps from when I stopped the YouTube video under windows as well as during shutdown).

Don't forget to reboot your machine with pci passthrough otherwise the application of the verbs won't work because your sound card is setup up for well... passthrough. There appears to be a way to disable passthrough for the device without rebooting, but rebooting is faster for at least me.

To provide some more concrete steps as to what I did:
The configure I used for JCS Qemu:
./configure --prefix=/opt/qemu/jcs --enable-kvm --enable-trace-backends=log --target-list=x86_64-softmmu --disable-werror
make -j$(nproc)
make install

How I ran it:
sudo /opt/qemu/jcs/bin/qemu-system-x86_64 -enable-kvm -hda win10.qcow2 -m 8G -smp 4 -vga std -device vfio-pci,host=00:1f.3,multifunction=on,x-no-mmap=true -trace events=events.txt >output.txt

python3 cleanverbs.py output.txt >verbs.txt
# Rebooted without intel_iommu and without vfio-pci.ids
# While playing sound:
sudo python3 applyverbs.py verbs.txt

With the verbs.txt, its likely that anyone on this thread with a Legion (or possibly a Yoga Slim as well) could apply these verbs and figure out what subset is needed. Which would be great because I don't know how much time I'll have now that it's Monday.

It's worth noting that it's entirely possible that the Slim needs some slightly different initialization.

head -562 verbs.txt > verbs-working.txt
sudo python3 applyverbs.py verbs-working.txt

With the first 561 verbs, I only get output from one of the speakers. It's possible we can go even lower though, I just don't have the time.

Putting the laptop to sleep and resuming results in non-working speakers. You will need to re-apply these verbs.

It's also possible that if your laptop stays on but is idle that the speakers will go to sleep and will need to be re-initialized in that case too.

I don't know if switching between headphones/bluetooth works yet, because a ways back I setup a combined audio device in my testing, and I don't think I'll have the time before work to figure out how I did it so I can undo it.

I haven't had time to test the mic yet.

Everyone, please test when you have free time. We're almost there!

[mysubstmp (mysubstmp-linux-kernel-bugs)]

I have very good news!! Thank you very much @Cameron!!!
This file verbs-working.txt worked (apparently) for the two speackers for me on ubuntu 20.04 Legion 7i 15IMH05 kernel 5.8.0-55.
I could even switch back and forth between the bluetooth headphones.
The mic also looks like it is working.

[mysubstmp (mysubstmp-linux-kernel-bugs)]

For those wanting to test it.
- Download the verbs-working.txt provided on https://bugzilla.kernel.org/show_bug.cgi?id=208555#c206 .
- git clone https://github.com/ryanprescott/realtek-verb-tools
- sudo python3 realtek-verb-tools/applyverbs.py verbs-working.txt
- put some audio to play

[mysubstmp (mysubstmp-linux-kernel-bugs)]

I am not sure I have sound on both speakers though.

[andreas (andreas-linux-kernel-bugs)]

Tried that on a Lenovo Yoga 7i with Ubuntu 20.04LTS:
- Started a Video in the browser
- running the patch as described
- and get a clear Sound on the speakers (as with the S3 patch)

GREAT work ...

[andreas (andreas-linux-kernel-bugs)]

It seems similar to the S3 patch that after some seconds of not playing audio the effect disappears. But could be started immedeatly.

Also attaching and deattaching the mic works as expected.

The Audio test in settings shows correct output with left speaker: "Front left" bt no with the right speaker.

As I mentioned above in my last comment, this is fixed by adding a few services to systemd. Follow the link I mention and it will work permanently.

I have the right verbs in a script that just runs the command on each line, instead of a wrapper as mentioned now lately. So keep that in mind when adding the services (what you want to run).

If you just run the script standalone, it will only work (kind of, has a few quirks you can do) "once" and you need to run it everytime before starting an audio source.

This is my last comment with all the info:

[cam (cam-linux-kernel-bugs)]

I should clarify that you only needed to play music while applying the
original verb.txt as those verbs appeared to start and stop the speakers
several times.

With verbs-working.txt, it doesn't matter whether or not if you're
playing any sound during the apply.

[cam (cam-linux-kernel-bugs)]

Thanks for sharing, Niclas!

Interesting that the verbs in your sitation were also 361. So I may have
already found the magic number in just 5 minutes of testing.

Yeah, it hardly can be a coincidence right? Well, I have everything working with this quite messy fix for now. And the new sof firmware was relased today, at least for debian. So now Im just waiting for a more complete and true fix to arrive.

And in my case, with a Samsung Galaxy Book Pro, I still havent found a way to get the keyboard brightness adjusted or even turned off. But thats for anoter thread.

Yes, also the audio/speaker config stays now stable for the last 30 minutes.

[cam (cam-linux-kernel-bugs)]

It stays up for a while... However, after over an hour, it stopped
working for me. I don't know the precise time, I just know it was more
than 1 hour and less than 2. Re-applying brought sound back of course.

Cameron,

the verbs file from Comment 206 has 562 lines. Did you manage to get it down to 361? Is the mic also working?

Thanks

[cam (cam-linux-kernel-bugs)]

Whoops, I remembered the size incorrectly.

It seems the mic is working for others.

Definitely not going to be doing much testing today. In addition to it
being a weekday, I have a Lenovo tech that's expected to be here soon to
fix an unrelated issue on this laptop.

Has anyone tested a 2021 Legion yet? I'm curious to know if this set of
verb works.

I've got it down to 317 lines, but at some point I lost my mic.
Thus, I need to further test it to make sure what screwed up the mic.

Really appreciate it. Of course please attach the verbs to the bug once
you've got it narrowed down.

I assume you've already tried 361. :)

I didn't pay special attention to the 361, but that is likely the one I will try
next.

Thanks, this is _very_ helpful! This looks really straightforward to implement.

Now for some newbie questions:

Going through the kernel code, I see that on resume, alc_resume() is called, which will call codec->patch_ops.init(codec), this covers the resume from sleep cases.

What about when the card itself (or its speakers so effectively the card) goes to sleep due to idle? Will the kernel automatically be made aware of this state? If not, how do we go about making it so the kernel is aware that the card will need to be re-inited?

Once the kernel is aware that the card is in a state where it will need to be re-initialized for use, will it call the init callback or is it some other callback?

Under hda_local.h, I see a number of actions are enumerated. Am I correct to assume we only need to cover the INIT case?
/* fixup action definitions */
enum {
        HDA_FIXUP_ACT_PRE_PROBE,
        HDA_FIXUP_ACT_PROBE,
        HDA_FIXUP_ACT_INIT,
        HDA_FIXUP_ACT_BUILD,
        HDA_FIXUP_ACT_FREE,
};

Thanks, again!

made a test sequence and audio output is between 300 and 400 (in steps of 8) available from 324 ...
also there are some higher numbers >1000 where my left speaker works.

so I assume there are similar blocks inside which lead to the same result

[andreas (andreas-linux-kernel-bugs)]

to be more concrete 91-150 bytes from the beginning and 301-348 make a working sequence after reboot.
These sequences can be found multiple times in the log, i.e. the on sequence on 889

[jmcherbuin (jmcherbuin-linux-kernel-bugs)]

Comment #208 works for me on my Legion C7i 82EHCTO1WW (Creator edition, same a the normal but with a better display) on Ubuntu 20.04.02 default kernel. But if I stop playing music 15-20 sec, I need to run the script again. I could leave with running the script once at boot, but having to do it all the time makes the solution more as a workaround, even so it is a progress, yes.

I don't know if it has to do with the S3 stuff as I have not got it completely. I am like this:

cat /sys/power/mem_sleep
s2idle [deep]

sudo dmesg | grep ACPI | grep support
[ 0.535533] ACPI: (supports S0 S3 S4 S5)

Which I understood means I am not impacted ?

[cam (cam-linux-kernel-bugs)]

Created attachment 297559
linux-5.12.12-legion-sound-0.0.1.patch

And here's a patch. PLEASE TEST! ...At your own risk.

This is against Linux 5.12.2, but will likely work against many others.

It seems to work even after resuming (but from the kernel code I see that sound cards are re-initialized on resume so no surprises there).

I'm unsure if this will resolve the idle sound issue. If your sound still works after 2 hours, we're good to go.

In my experience, it takes less than 2 hours before the speakers power down, but I don't know how long that is. 2 hours is a pretty safe test.

I'm using the 562 verbs until we can get it narrowed down because we know for certain they work.

I'm not sure what, if any, chain_id should be set for the Legion hence it being commented out and the TODO. However, it seems to be working without it for now.

Also not sure if I'm fully following all the proper conventions, but that can be cleaned up with feedback.

Unless the Yoga has the same vendor/dev ID's, this won't work there. I'll need to get those and add them to the patch. Same for newer Legion models.

Enjoy!

[cam (cam-linux-kernel-bugs)]

I've done some testing with the patch. Sound still works after a few hours of activity for me so far.

One big problem I've found is that if I connect head phones and then disconnect, output from the speakers no longer works unless I apply the verbs.

If I connect head phones and never play any sound while they're connected, speaker output will still work. This suggests the hardware turns off the speakers if it detects head phones are the active output, which would make sense.

I spent a long time trying to figure out how to re-initialize the speakers when head phones are unplugged. I couldn't figure out how to do it. Is there anyone who could please provide guidance here?

[andreas (andreas-linux-kernel-bugs)]

Status on the Lenovo Yoga 7i:
- only left speakers work with the patch, but it seems to be stable for hours
- I was in the opinion that I can narrow down to some smaller sequences (speakers off, speakers on), but that was partly not reprodcable after reboots. Additionally it turned out that the smaller sequences affects the left speaker only. But i can only hear that after S3 resume since the patch only initial enables the left side.
- when doing the S3 workaraound both speakers work, but this stops when there's no activity for 10-20 seconds => would be interesting if the driver generates a similar sequence as the patch after resume from S3 ?
- using the patch afterwards, the sound stays on both speakers without audio activity for minutes

[niclas (niclas-linux-kernel-bugs)]

Again, its not a great solution, but what I did was to make a systemd service that has the wants of hibernation and sleep. So when systemd detects that the laptop is woken up from either of those, ie resume, it just runs the script again.

That fixes the problem superficially and I have constant sound and dont have to think about it.

Now this is on my Samsung Galaxy Book, so I have both speakers working fine et al. But for now and until a better fix comes along, it makes it seamless.

Thanks for that. My summary is mainly ment for the results of Cameron which is a significant step in a patch also for the Yoga 7i ...

Thank you so much! This worked somehow on my lenovo legion 7i 15IMHg05.
It's not permanent though as audio needs to be played constantly for it to last longer, otherwise it go back after few seconds. I hope that the fix will be patched to the kernel after some fine-tuning as I noticed that applying the verbs the quality of audio is not quite good compared to how it was on windows. But who I am to complain, I'm just happy there is a workaround to use keep me using linux on my machine.

Also it's weird that the fix worked for my laptop even though I have the issue with mis-detected codecs: the specs of my laptop list ALC3306 while alsa reports ALC287.

[cam (cam-linux-kernel-bugs)]

Applying the original 562 verbs brings up both speakers though? If so,
weird that this patch only brings up one.

Please share your results if you try. I probably won't have the time to
try this for myself for well over a week.

I haven't had a chance to try comparing the audio quality, but I have wondered if that might be the case... How did you compare? Was it with the same application? Ie, maybe FireFox/Chrome and YouTube?

Is anyone else seeing differences?

I've ran firefox with the same youtube video and I also felt the quality is lower on Linux. I don't know how to describe the difference though.
It is not a significant difference for me.
I am good with the current quality, but there is definitelly something to improve there.

[cam (cam-linux-kernel-bugs)]

I just did the same thing, and my reaction is the same. The quality is
lower under Linux, but it's not a massive difference. Maybe it sounds
more tinny under Linux?

Not sure what controls that... Maybe coefficients?

I would say the current quality is still a massive step up over having
had no sound at all.

My current priority is to fix the headphone issues. I want the speakers
to start working again after unplugging from the headphone jack.

I guess you already checked, but just be sure there is no "sound enhancement" activated under Windows... On my Lenovo, there is some sound enhancer activated by default in Windows.
Seems we get near to find a solution, I'll have to test on my 13S Gen2 all of this (and I will report back on the ALC3306 thread).

I didn't know about the enhanced sound. Is that controlled in Lenovo

Yes it's there in Lenovo Vantage (surround stuff, or enhancement, or I can't remember the name).
I always remove those stuff, whatever they call it, because I prefer "natural" sound...

I've tried to follow some ideas in the dump. Don't know if that brings anybody further insights.

# 1. enables output of COEF
echo 1 |sudo tee /sys/module/snd_hda_codec/parameters/dump_coef
# shows the result for the ALC287
cat /proc/asound/card0/codec#0
# thus allowing to dump the different COEF register states after several actions

=> if I'm comparing the output before and after S3 resume, I can't see a significant difference

# 2. enable hda traces
echo 1 | sudo tee /sys/kernel/debug/tracing/events/hda/enable
# read traces
sudo cat /sys/kernel/debug/tracing/trace >/tmp/1
# result in output like:
# alsa-sink-HDA A-1107 [000] .... 9249.632894: hda_send_cmd: [0000:00:1f.3:0] val=0x00170500
hda-decode-verb 0x00170500
raw value = 0x00170500
cid = 0, nid = 0x01, verb = 0x705, parm = 0x00
raw value: verb = 0x705, parm = 0x0
verbname = set_power_state

My main idea is that there must something happen after a S3 resume which leads to a working speaker config, and it must be in the driver code?

I've tried to catch that and will upload the results soon ...

Additionally looking in the kernel code you see:
- HDA_CODEC_ENTRY(0x10ec0287, "ALC287", patch_alc269)
- for alc269 you find
- codec->patch_ops.resume = alc269_resume; => special resume handling
- in alc269_resume:
/* on some machine, the BIOS will clear the codec gpio data when enter
 * suspend, and won't restore the data after resume, so we restore it
 * in the driver.
*/

=> would explain, why S3 resume is working
- maybe some additonal toggle_power_output commands are also helpful

Is that something which can be helpful or a complete misleading path?

How direct can the dumps be translated to verbs? If translating isn't an
issue (I don't know what the dump output looks like yet but I should
really look), that should be a sufficient set of verbs to get both
speakers going in a patch for the Yoga.

Hopefully the dumps are a working alternative to running a Windows VM
with PCIE passthrough... It's quite a bit of work to setup.

I think these traces will very useful. Perhaps I can also use them to
determine what's going on when I plug headphones into the jack and
remove them so we can handle that appropriately.

Well, this is like the other issue with my patch where after unplugging
headphones, speaker output is gone again and can be r...

Hmm. The cut off point in verbs-working.txt is almost arbitrary. I started from an arbitrary point in verbs.txt and found the first place from that original starting point that gave me 2 working speakers on my Legion.

It's possible if we go further down through verbs.txt we get to a point where the audio quality improves I suppose.

I'm keeping my focus on the headphone issue for now before I try anything with the sound quality issue. Hopefully someone else can play with this in the meantime. I don't think there should be any conflict between applying verbs and using the patch. Or at least none that wouldn't exist when not using the patch anyway... :)

[cam (cam-linux-kernel-bugs)]

Created attachment 297569
linux-5.12.12-legion-sound-0.0.2.patch - headphone fix

Headphone issue is fixed.

I believe unmute hooks are called whenever jacks are either plugged or unplugged. We'll probably want only want to send the verbs when we're in the unplugged state. I'll update that at some point before I try for a final patch.

I know I implied I'd work on audio quality next... But how many people would like me to work on getting the Yoga support squared away so it's on par with the Legion support (ie, you get both speakers)? I suspect functionality is more important than what appears to be a smallish loss of quality.

Also, Legion and Yoga owners, please test. Let me know of any issues. In particular, let me know whether or not speaker output still works after plugging in and then unplugging in headphones.

[cam (cam-linux-kernel-bugs)]

Created attachment 297571
linux-5.12.12-legion-sound-0.0.3.patch - actual headphone fix

Whoops, patch 0.0.2 is exactly the same as 0.0.1. Please use this one. Everything else from my previous message still stands.

[cam (cam-linux-kernel-bugs)]

Going through the alsa-info results posted in this bug and looking at the subsystem ID's, none of the models are supported by my patch except for the Legion.

For the non-Legion users who have built their kernels with my patch applied, are you sure you aren't still using the S3 and/or the verb workarounds?

In this bug, I've found the following models:
Yoga Slim 7
Yoga 7 14ITL5
Yoga Duet 7
Legion 7

In sound/pci/hda/patch_realtek.c, my patch adds this line:
SND_PCI_QUIRK(0x17aa, 0x3813, "Lenovo Legion 7", ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS),

The ID's for all the other models are different which means these kernel patches should only affect Legion 7's (and possibly only the 2020 model). Therefore the patch is probably doing nothing for you and you likely have one of the other workarounds in place (S3/verbs). But please look into this and update me one way or the other.

Interestingly, there's a quirk that does match the Yoga Duet in patch_realtek.c:
SND_PCI_QUIRK(0x17aa, 0x3818, "Lenovo C940", ALC298_FIXUP_LENOVO_SPK_VOLUME),

But I presume the "Lenovo C940" fix doesn't work for the Duet.

I have enough info from alsa-info for these other non-Legion models to create a patch that will apply to them. If applying verbs-working.txt works for your model, then a patch would work as well (except your speakers presumably wouldn't stop working after a period of time, etc). Just let me know.

[mysubstmp (mysubstmp-linux-kernel-bugs)]

I've patched kernel 5.8.0-59 for Ubuntu 20.04.2/Legion 7i and everything worked well!
Headphones turn the speakers off when I plug them in and back on when I plug them off.
I had adapt the patch because the kernel version was different than the one in Comment #252 but that was easy.

You sure it is the ALC287 ?
For me it make no sens the driver work for us and not for you.
In case of your computer recognize the sound card but the speaker don't work, it seem to be logic, but don't recognized, with a working kernel for us, I'm surprised.
For me after 5.11.5 it stop working. I write 5.11.5 cause of that point. Do you have try 5.11.5 or older ?

System was updated to 5.8.0-59-generic #66 today and:
- S3 fix is oncemore working as expected (S3 can be enabled in this version onecemore by overwriting tje DSDT table) => both speakers enabled
- also Cameron's workaround (verbs-working.txt) is doing the same job as before => left speaker enable

trying to setup a kernel compilation environment to check also the kernal patch.

No, I'm not, although the problem sounds quote similar. This may be a coincidence, but I'll keep an eye on this issue.

First time this "workaround" enables both speakers (so far only left speaker).

Great ....

[cam (cam-linux-kernel-bugs)]

sycxyc,

Great work!

Is this work from the verbs I attached to the ticket or did you find these verbs on your own?

Can you give me your alsa-info.sh? You can either post the the output here or upload it and share the URL.

With all this and your verbs, I should be able to update the patch to cover your machine.

woody64,

You're on *buntu 20.04, is that right?

Can you please provide your alsa-info to me? Sorry if you've already
shared it. I searched through your posts in this bug and couldn't find
it, but there are a lot of comments so it's possible I missed it.

That's one from the begin of the month:
https://media-cdn.ubuntu-de.org/forum/attachments/23/21/9255949-alsa.txt

[cam (cam-linux-kernel-bugs)]

It definitely is. What's missing a sequence of HDA verbs specific to
your model of laptop to get the speakers going. This probably sets the
speaker amplifier chips.

Can you share your alsa-info? Skimming through the bug, I wasn't able to
find for you.

Have you tried the verb work around (without the S3 workaround)? How
well does that work for you?

These verbs are based on your attachment, but the right speaker does not work.
I tried to fix the right speaker issue by changing the following.
```
 0x20 0x500 0x24
-0x20 0x400 0x42
+0x20 0x400 0x46
```
Here's the Alsa-info for my machine. It may be similar to the yoga 7i.

http://alsa-project.org/db/?f=68337a779c3297142b0afb022125fbf32f1a6c17

[cam (cam-linux-kernel-bugs)]

The Legion verbs I provided don't enable your right speaker. Got it.

But I'm unclear on your set of verbs. Do YOUR verbs enable your right
speaker?

Thank you for the alsa-info. You have the same hardware ID's as woody64
and the same problem with the right speaker. This is progress!

DavidLenovo,

Whoops, I misunderstood who you were responding to. But having your
alsa-info would also help.

Roland,

Can you also share your alsa-info with me? Even if you do have an
ALC287, it's likely that your Dell requires a different sequence for
initialization.

Legion 7 2021 (16achg6) here! (According to specs it's an ALC3306 but according to Alsa it's an ALC287): http://alsa-project.org/db/?f=d3f255a8ac60504ad70c27c5cc36e6e7400eaab3

I'll try and figure out how to apply a kernel patch and see if that helps!

Yes, the small sequence has worked for me on a Lenovo Yoga 7i without and with S3 workaraund.

When using the S3 workaround without firing further outputs to the audio device and audio is then oncemore lost the verb sequence can be used to restart the Audio for both speakers.
Afterwards the sound stays for a longer period, can't say when the sound disappears.
So it has the same effect in this setup as in the setuo without S3 enabled or with S3 enabled and not used.

[cam (cam-linux-kernel-bugs)]

Have you tried the kernel patch (without the verb workaround)? If so, I
assume it didn't work?

Thank you for the info. I'll add support for this model to the patch
likely at some point today.

-Cameron

PS: I didn't know for sure these were even out... Each time I've
checked, the Lenovo site says "coming soon". With the progress I've
made, I'm strongly considering getting one. Therefore even if my patch
doesn't have the right verbs for initialization, I'd likely be able to
add support once I had the hardware.

linux-5.12.12-legion-sound-0.0.4.patch - updated headphone fix, more models supported

I've updated the headphone fix. The automute_hook wasn't the fix. Simply having an automute_hook defined means snd_hda_gen_update_outputs() is not called. The call to snd_hda_gen_update_outputs() results in do_automute() being called, which shuts down the speakers putting them into a state where they need to be re-initialized. Setting automute_speaker to off avoids do_automute() breaking the speakers and it seems we can trust the hardware to do the right thing.

So please test without any of the other work arounds. Make sure speaker output resumes after unplugging headphones while sound is playing.

The good news is that this patch should now affect more than the original 2020 Legion. Here are the models that can test this patch:
Lenovo Legion 7i
Legion 7 16ACHg6 (2021)
Lenovo Yoga 7 14ITL5
Yoga 14cITL 2021

In the case of the last 2 models, you should only see output from one speaker as the same verbs are being applied as in verbs-working.txt (for now).

In the case of the 16ACHg6, I have no idea what to expect. Depends if the speakers require the same (or very similar) initialization sequence or not.

Vincent Morel,

I don't have a natural setting in my Vantage... But I do have a setting to enable/disable Dolby sound. Disabling it causes the sound under Windows to sound like it does in Linux. Being able to switch back and forth on the fly with the Dolby switch in Vantage under Windows instead of waiting for reboots... The difference is more stark

However, I think I can live with it.

Especially since it looks like there's really nothing more to be done from my side at least:

I have a Legion 7 2020 (alsa-info here:http://alsa-project.org/db/?f=c62e1da70c65a4709d137b2a48204cd6ebdeaaa1) and a bit of a Linux newbie. I'm on Pop_OS; would you explain how to apply this patch? My headphone/usb headphones work fine but speakers aren't working.

[cam (cam-linux-kernel-bugs)]

You need to pull the kernel source, know how to apply the patch, how to
configure the kernel, know how to build your kernel, and then to install
it. If you're new to Linux, this may not be for you.

I'm *really* hesitant to provide some random kernel packages. From a
security point of view, I would strongly recommend against installing
packages (especially kernel packages) from some random person's web server.

Hopefully someone following this bug has the time and know-how to setup
a proper PPA for kernel packages with this patch for *buntu. It would
help a lot of people, and it'd be nice to have some more feedback too.

At least I was able to backport and test the patch to 5.8.0-59-lowlatency.
And it works.

So far I was not able to use the small version from sycxyc inside the patch. There it has no effect?
But applying from outside via verb results in running both side speakers.

I tried sycxyc's stuff yesterday, but wasn't able to get it to work. I
haven't tried the updated verbs from this morning yet.

The kernel patch only works for one speaker though, correct?

legion-alc287-0.0.4.patch - snd-hda patch

This is _NOT_ a kernel patch. It's a patch file for snd-hda, and therefore is much easier to try.

*face palm*

I forgot this could be done. This effectively does the same thing as the kernel patch... Except without having to patch, recompile, etc the kernel.

This works for me on the 5.11.0-22-generic vendor kernel for *buntu 21.04 on my 2020 Lenovo Legion. Here's how to utilize it:

1. Download the "legion-alc287-0.0.4.patch" from this bug.

2. Copy it to /lib/firmware/legion-alc287-0.0.4.patch

3. Create/open "/etc/modprobe.d/lenovo-fix.conf" in your favorite text editor. Ie, "sudo nano -w /etc/modprobe.d/lenovo-fix.conf"

4. Set the contents of "/etc/modprobe.d/lenovo-fix.conf" to be following then save and exit:
# Patch file to enable output on speakers.
options snd-hda-intel patch=legion-alc287-0.0.4.patch

5. Reboot

6. Test your sound and report back here with your results.

This patch file should work as well as applying verbs-working.txt or using the kernel patch (provided your model is supported by the patch).

Some more info on snd-hda patch files can be found here for those wanting to experiment:
https://www.kernel.org/doc/html/latest/sound/hd-audio/notes.html

[cam (cam-linux-kernel-bugs)]

Forgot to add... If you need to disable this patch, you can simply delete /etc/modprobe.d/lenovo-fix.conf.

Do you see any hint in dmesg that the patching is applied?
I have tried it for the Yoga but with no effect (exchanged the deviceid). I see in alsa-info that the hda-intel module is started with patch=... but no further info.

[alex (alex-linux-kernel-bugs)]

No success here on a Legion 7 2021 (16ACHg6) with either the patch or full verbs list (although the speakers did make a tiny sound when rebooting the machine this time).

Is there anything I can do to figure out which verbs are needed? Perhaps it's something to do with ALC3306 vs. ALC287?

I really appreciate all the work you're doing here Cameron!

I have a Lenovo legion 7i 2020 and the verbs work for me. The ALC3306 vs. ALC287 should not be an issue: My laptop is listed to have ALC3306 in Lenovo Specs page but Alsa reports it as ALC287. Regardless I have sound now using the fix.

When applying the verbs while playing sound, do you hear anything? Maybe
a very short blip of noise?

So far it sounds like the issue is that the 16ACHg6 requires a different
list of verbs. However, since you said you've heard noise during start
up, there might be some slight initialization overlap).

 From my research, it sounds like the 16ACHg6 is the Thai (or perhaps
South East Asian) version of the 16ACH6. If I end up with a 16ACH6 once
they come out, I'd be able to (hopefully) figure what verbs are needed
there myself.

Hello, just tried to apply the patch to my 13s Gen2 ITL (ALC3306) and no change despite the fact alsa-info tell me the patch is applied... :(
I should probably try to dump the hda-verb from windows with the small utility I cannot find again (have to search a little)...

[cam (cam-linux-kernel-bugs)]

The snd-hda patch just applies the same verbs as the kernel patch. If
the kernel works, but this does not, then the snd-hda patch has problems
with non-Legion machines, and you would be the 2nd non-Legion user the
snd-hda patch does not work for so far.

But then, I don't know if the kernel patch or these verbs work for the
13s Gen2 ITL at all yet so youre problem is that we don't yet know of a
sequence compatible with your model yet.

Regardless of your model, please report back on your experience. Does it work the same as before? Better? Worse?

legion-alc287-0.0.5.patch - snd-hda-intel patch

This is another snd-hda-intel patch. _NOT_ a kernel patch.

This works for the Legion. It may work for the Yoga 7 with output from only one speaker. I'll upload a separate snd-hda-intel patch for the Yoga 7.

I've streamlined the instructions slightly:

1. Download the "legion-alc287-0.0.5.patch" from this bug.

2. Copy it to /lib/firmware/legion-alc287.patch. Ie, "sudo cp legion-alc287-0.0.5.patch /lib/firmware/legion-alc287.patch"

3. Create/open "/etc/modprobe.d/lenovo-fix.conf" in your favorite text editor. Ie, "sudo nano -w /etc/modprobe.d/lenovo-fix.conf"

4. Set the contents of "/etc/modprobe.d/lenovo-fix.conf" to be following then save and exit:
# Patch file to enable output on speakers.
options snd-hda-intel patch=legion-alc287.patch

5. Reboot

6. Test your sound and report back here with your results.

NOTE: To disable the patch, remove /etc/modprobe.d/lenovo-fix.conf and reboot.

This patch file should work as well as applying verbs-legion.txt or using the kernel patch (provided your model is supported by the patch).

I found that enabling auto-mute mode from alsamixer and then disabling it makes the speaker inactive. Using the debug mode of applyverbs.py, I can quickly determine the 5 line sequence that activates the left speaker without restarting or suspending.

verbs-working.txt has two similar sections. The sequence used to activate the left speaker is at the end of the first part. It can be assumed that the later part controls the right speaker. After executing the later part, the first two lines must be executed to activate the left speaker, and it can be determined that the first two lines are used to switch speakers. I tried to modify the right speaker section and successfully activated it.

The sequence of 5 lines to activate the speaker is repeated 2 times in succession and they are probably safe for the separation point.

I modified applyverbs.py so that it skips comments and empty lines, which makes it easier to test and mark up.

This is another snd-hda-intel patch. _NOT_ a kernel patch.

This works for the Yoga 7. AFAIK, it should cover at least both the Yoga 7 14ITL5 and the 14cITL. I think these are likely Yoga 7 models for different regions.

3. Create/open "/etc/modprobe.d/lenovo-fix.conf" in your favorite text editor. Ie, "sudo nano -w /etc/modprobe.d/lenovo-fix.conf"

4. Set the contents of "/etc/modprobe.d/lenovo-fix.conf" to be following then save and exit:
# Patch file to enable output on speakers.
options snd-hda-intel patch=yoga7-alc287.patch

5. Reboot

6. Test your sound (including with plugging and unplugging headphones while sound is playing) and report back here with your results.

NOTE: To disable the patch, remove /etc/modprobe.d/lenovo-fix.conf and reboot.

This patch file should work as well or better than applying verbs-yoga7.txt or as well as using the kernel patch (provided your model is supported by the patch).

Some more info on snd-hda patch files can be found here for those wanting to experiment:

I forgot about the debug mode of applyverbs.py.

I was thinking of making the same modifications to applyverbs.py... Can you attach your version to this bug? It might also be worth sharing your changes with the original author too.

Again, great work!

Very good work!
That does not look so trivial though. The verbs-working.txt has more than 500 lines and finding those 5 lines looks not so easy. The debug mode makes it easier to find when to stop but not when the sequence starts.

I tried to follow the information about installing Qemu (https://github.com/ryanprescott/realtek-verb-tools/wiki/How-to-sniff-verbs-from-a-Windows-sound-driver), but ran into problem and I'm not able to install the driver in windows (I have an error while starting qemu abut my soundcard address

).
So sadly I'm not able to get the hda_verb output here... :( Would love to help but for today I'm done. Maybe will have time sunday to try something else.
Is there a program I can run into a windows partition to sniff the hda? I'm almost sure I saw something but I cannot remember where...

Are you referring to RtHDDump_V236 binary?
Check Comment #236.

Yes, it's a known issue that the sound card is non-resettable. The
really good is is that this generally isn't a problem.

  If through your testing you start having problems, you might need to
stop/start the VM, and in some cases, fully shut down the machine. I did
tons of testing, and very rarely did I need to do anything more than
restart the VM. Only twice did I need to shut off the entire laptop.

Anyway, getting Windows to use the right driver is a bit tricky, but it
can absolutely be done. I don't have the same machine, but looking at
your alsa-info, this should mostly work.

I don't have the URL for your laptop, but here's the Lenovo version as
an example:
https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/legion-series/legion-7-15imhg05/81yu/81yucto1ww/mp1t35d3/downloads/driver-list/

Find the equivalent part of the Lenovo site for your model and then
download your sound driver.

When opening the driver, choose to extract the driver (it won't hurt if
you also install it).

Anyway, here are the instructions I posted earlier in this bug:

You need to force the device expanded above to use the RealTek driver. I was able to force it by *extracting* rather than installing the sound driver from the Lenovo site. Selecting update driver on the sound device listed under "Sound, video and game controllers", and from there I did:
"Browse my computer for drivers"
"Let me pick from a list of available drivers on my computer"
"Have Disk"
Browse to: C:\Drivers\Audio\201211706.15485923\Realtek\Codec_8975.1\HDXLVSST.inf
Press Ok
You should see "Realtek High Definition Audio(SST)" as an option. It's the only option for me)
Next
Yes
Restart the VM when prompted

Hopefully after these steps, you'll see the "Realtek High Definition
Audio(SST)" device in device manager as your sound card and you'll get
sound from windows.

By getting a Win10 VM running with the JCS Qemu means you're a good
chunk of the way done.

-Cameron

PS: I looked into RtHDDump_V236 and I don't think it's anything I needed
for my particular case. It seems it can be used to figure out what pins
should be connected to what. We'll see if you need any of that, but not yet.

Yes!
I'll force the driver install. Thanks for your support. I have to go now
but sure I will try all of this. On a side note, the Qemu I compile from
the Git do not seems to start, just stuck.
The one from the Ubuntu repo starts with no problem.

What were your ./configure arguments?

Here were mine:
./configure --prefix=/opt/qemu/jcs --enable-kvm
--enable-trace-backends=log --target-list=x86_64-softmmu

Then I would run it with this script:
#!/bin/bash

_qemu=/opt/qemu/jcs/bin/qemu-system-x86_64

sudo $_qemu -enable-kvm -hda win10.qcow2 -m 8G -smp 4 -vga std \
-device vfio-pci,host=00:1f.3,multifunction=on,x-no-mmap=true \
-trace events=/path/to/events.txt

The contents of events.txt:
-vfio_region_read
vfio_region_write

I'm not sure if the events.txt is needed for JCS Qemu, but they don't
hurt. :)

Does it always hang? I did notice this version of qemu would often hang
during OS startup (less than 50% of the time though). Glad to know it
wasn't just me. :)

[pablitar (pablitar-linux-kernel-bugs)]

Hey!

I've tested some of these fixes on my Lenovo 16ACHg6 and had no luck.

What I've tested:
- Using the applyverbs.py with verbs-working.txt
- Applying the legion-alc287-0.0.4.patch as per instructions
- Applying the legion-alc287-0.0.5.patch as per instructions

Something that may be important is that this new model is running an AMD processor and the sound controller appears as:

'Audio device: Advanced Micro Devices, Inc. [AMD] Family 17h (Models 10h-1fh) HD Audio Controller'

On Alsa Mixer, it says the "Chip" is ALC287 but the "Card" is HD-Audio Generic.

Is that important? I'm bringing this up because the instructions say:

# Patch file to enable output on speakers.
options snd-hda-intel patch=legion-alc287-0.0.4.patch

And the intel part there may be something to change?

But honestly I'm clueless so this may be waaay off.

Thanks in advance!

[cam (cam-linux-kernel-bugs)]

You're not the first person to report that these fixes don't work for
the 2021 Legion.

Can you post your alsa-info?

I'd like to order one as soon as they become available here in the USA,
but I'm unsure what the availability will be. If I managed to snag one,
I'll work on getting sound working there too.

I performed the above steps on a Yoga 7 14ITL5 (reporting "Realtek ALC287" from alsa-info) running Elementary OS 6 beta (Ubuntu 20.04 LTS) with kernel 5.8.0-55. It did not work. Only speakers do not work. All other audio (headphones, HDMI, bluetooth) works.

[cam (cam-linux-kernel-bugs)]

Woody is reporting the same thing also with 5.8.0. Either The
snd-hda-intel patches are no good for the Yoga 7 and/or 5.8.0 may not be
recent enough for some reason.

Woody did say that the kernel patches do work , fortunately.

Is the yoga7-alc287-0.0.5.patch working on anyone's Yoga 7?

You're welcome. I understand the frustration!

Can you or anyone else with a Legion 7 16ACHg6 check if your CPU has
IOMMU support? I'm not able to find an answer to this one way or
another. If so, likely the same trick can be used to find the codec
initialization verb sequence.

It only takes 5 backtraces to find the starting line, but the line-by-line test is not safe and may result in the need for a forced reboot

As far as I have seen, the snd-hda patch does not work on my Ubuntu (!) system. Neither for 5.11 nor for 5.8.
My understanding is that the firmware patch does not load as expected in Ubuntu 20.04. And it is not due to the laptop model (Yoga).
Maybe Ubuntu has something in between (udev) that needs a different configuration for firmwares to make it work.

What has worked so far (minimum verbs/Cameron - but also very small version from sycxyc) :
- the kernel patch (5.8.0-59) => pretty sure it will also work with 5.11/5.12
- The applyverbs.py (thx to sycxyc for doing the comment modification, I wanted to do that also ..)
- the S3 resume method

[cam (cam-linux-kernel-bugs)]

That is a resounding yes! Unsurprisingly for AMD, PCI passthrough is
available.

Is there anyone with a Legion 7 16ACHg6 who's up to setting up pci
passthrough for their sound card and compiling JCS's Qemu all to run a
Windows 10 VM? Someone can either try to do that for themselves or wait
for me and hope there's sufficient availability.

I'll see if I have the time. And if I can hahaha.

Is there a clear list of instructions in this thread? I'm lost in all the messages.

I can read the thread trying to compile what to do. But if someone could point me where to look, maybe that can save me an hour or two.

[cam (cam-linux-kernel-bugs)]

I posted some instructions, but I've lost them in the thread too. :p

I used this document to setup the PCI passthrough:
https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF

PCIE devices are in groups, and ALL of the devices in a group must be
setup for passthrough together. However, I found I only needed to tell
qemu about the sound card.

On my 2020 Legion 7i, the sound card is in a group with 3 other devices.
Fortunately, it didn't cause me any issues to set them all up for
passthrough as none were vital to running the system. This will probably
be the case for you, but we'll see.

The article provides a script that lists all the PCI groups and their
associated devices that is really helpful:
https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Ensuring_that_the_groups_are_valid

Here's part of the output of the script showing the sound card and the
group that it's in as well as the other devices in that group:
IOMMU Group 14:
         00:1f.0 ISA bridge [0601]: Intel Corporation Comet Lake LPC
Controller [8086:068d]
         00:1f.3 Audio device [0403]: Intel Corporation Comet Lake PCH
cAVS [8086:06c8]
         00:1f.4 SMBus [0c05]: Intel Corporation Comet Lake PCH SMBus
Controller [8086:06a3]
         00:1f.5 Serial bus controller [0c80]: Intel Corporation Comet
Lake PCH SPI Controller [8086:06a4]

Here's JCS's Qemu. JCS just made some changes that added logging to pick
out HDA verbs.
https://github.com/jcs/qemu

You'll need to make sure you have the build dependencies for qemu.

Here's what I used for configure:
./configure --prefix=/opt/qemu/jcs --enable-kvm
--enable-trace-backends=log --target-list=x86_64-softmmu

You can change the prefix to whatever you personally prefer of course.

 From there follow up with the usual "make && make install"

If you get this far, I can provide more guidance on where to go. Vincent
Morel has started working on the same thing, but with an entirely
different model of Lenovo laptop.

If you have trouble, also feel free to reach out for help.

Here's one my last posts to Vincent. It has some instructions on how I
got the correct driver working with the passed through sound card in the
Windows 10 vm:
https://bugzilla.kernel.org/show_bug.cgi?id=208555#c301

Of course those driver instructions are for my Intel based 2020 Legion
7. You may have different paths and you may need to try several
different drivers in the archive before one works. In my case, it was
the very last driver that ended up working for me.

A heads up that I'm going to have poor availability this weekend. I'll
be able to still to respond to emails at least, but my responses will be
slower and less frequent.

Finally I have also a running patch kernel for 5.11.0-22-lowlatency on my Ubuntu 20.04 Lenovo Yoga 7i.

Could not use the diff file directly but copied parts of the diff code directly in the source.

Can you share the output of this script on your system?
https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Ensuring_that_the_groups_are_valid

What is the command line your kernel is starting with?
cat /proc/cmdline

Do you know if you're seeing the sound card show up in device manager
but as the incorrect device?

Ignore the "Cannot reset device" message. It's likely not a problem for
your sound card. I get the same message. The good news is that likely
you are successfully passing the device to qemu, but the above will help
me confirm that.

Where did you download the driver from?

[cam (cam-linux-kernel-bugs)]

Things are not quite right. You do seem to have the right sound device
picked out, but you need to pass all the devices.

Here's  your relevant IO group:
IOMMU Group 11:
         00:1f.0 ISA bridge [0601]: Intel Corporation Tiger Lake-LP LPC
Controller [8086:a082] (rev 20)
         00:1f.3 Multimedia audio controller [0401]: Intel Corporation

         00:1f.5 Serial bus controller [0c80]: Intel Corporation Tiger
Lake-LP SPI Controller [8086:a0a4] (rev 20)

Your kernel command only lists your sound card. It should all of the
devices in this group.

For example, I have:
vfio-pci.ids=8086:068d,8086:06c8,8086:06a3,8086:06a4

Yours needs to be:
vfio-pci.ids=8086:a082,8086:a0c8,8086:a0a3,8086:a0a4

In my experimentation in getting this to work, I also did not set
"iommu=pt". You might try removing that as well.

Hi all,

Just jumping on to say that, like <email address hidden>, I have a Duet 7i. They seem to have gone quiet recently so I thought I'd pipe up after this flurry of activity with the verbs. Unfortunately applying the 'verbs-working.txt' using the python script has not worked for me. I'm now following the qemu guide to try to determine the verbs, so will report back when I have something.

[dantahoua (dantahoua-linux-kernel-bugs)]

Ok,
updated the kernel param, now I have
initrd=\EFI\Pop_OS-b0da9465-3702-45ac-91d3-7ca24016e875\initrd.img root=UUID=b0da9465-3702-45ac-91d3-7ca24016e875 ro quiet loglevel=0 systemd.show_status=false splash pci-stub.ids=8086:a082,8086:a0c8,8086:a0a3,8086:a0a4 intel_iommu=on

Try with or without "iommu=pt"

Still no luck, no hcnag ein the VM.
Note that since I added those 3 more adress from the group to the param, my audio show only "dummy" output in control panel of Linux.

My VM start command is:
#!/bin/bash

<email address hidden> to BCC so we can avoid spamming with
trouble shooting. When we resolve this, we can share our findings.

(also check your spam folder for messages directly from me).

Linux should only have the dummy device as device is no longer available
to the host OS. That's good!

What do you see under system devices?

linux-5.12-legion-sound-0.0.6.patch - Early Gen2 support

No Legion changes.

For the Yoga 7, automute_speaker is no longer disabled. This is needed for the Legion, but not for the Gen2. I want to see if it's needed for the Yoga 7.

Early Gen2 support. Confirmed working for Vince Morel who is also working on getting those verbs trimmed down. :)

Yoga 7 users, PLEASE test and see if you still have speaker output after unplugging headphones while playing sound.

For the 0.0.6 patch, support was specifically added for the 13s Gen2 ITL. I Should have been more clear.

Anyhow, these are the verbs from Vince Morel. Thank you for expending the time and effort to setup PCI passthrough, build/run JCS Qemu, and fight with Windows to get the correct sound drivers working!

Perhaps some other 13s Gen2 users are out there who can take some time to look at these verbs and help narrow them down to what's needed.

On my Yoga the patch works also after headphones in/out.

Are you sure your new module is installed correctly?

Maybe place a

inside the alc287_fixup_legion_yoga7_speakers function and check afterwards via
dmesg.

linux-5.12-legion-sound-0.0.7.patch

Now that it's time to start moving away from just trying to get things working to having something that might actually be accepted into kernel, I'm changing how we're handling the verbs. In order to (hopefully) follow convention, I'm using the HDA_FIXUP_VERBS method to pass the verbs instead of manually calling a function to send them.

2020 Legion, 13s Gen2, and Yoga 7 are still the only supported models. I don't expect any issues, but please report any that come up.

In other news, I'm working on some documentation for the linux-realtek-alc287 GitHub project that I will hopefully have completed by this week so that others can try to reproduce this process and get sound out of their laptops. Thank you, Thiago!

Ganesh,

Thank you for your feedback. Can you share your alsa-info?

When you say post update, do you mean applying the latest patch attached to this bug report or are you referring to the latest kernel update for Fedora Rawhide?

This is a patch to be applied against the source of a 5.12.x kernel. You
would then need to compile, install, and boot to this kernel.

There are likely instructions on the net to help you do this with your
distribution. However, if this is something you're not comfortable with,
I'd suggest waiting these fixes to eventually make it into the kernel.

In the meantime, there is a temporary work around with applying the
verbs (you'd want the vebs for your model of laptop). There are caveats
with the "applying the verbs" method that are discussed in the bug.

I just performed, a regular system update, using dnf update command, and after all the packages were installed, I reboot the system, since then my sound cards are not being detected.

Here is the alsa-info:

Your laptop has an  ALC293 and was originally working. This bug is for
Lenovo laptops with ALC287's whose sound never worked, and therefore
these issues are unrelated.

Sounds like you need to file a bug report with Fedora.

David, it's the ACL711. I didn't find any bug reports regarding this chipset, nevertheless I assume that the problem might be similar to the ACL287 reported here, since the symptoms are the same. Sadly, the verbs from this report don't work for me, so they might be different to the ACL711. I fear I have to patch qemu and try to find working verbs for my system on my own :-(

Thank you for those instructions.
I was able to get the sound working on my 13s gen2 ! I'm using Fedora 34 and applied the patch to kernel 5.12.14.

I'm finding the sound quality to not be as good as it is on windows oem install.
Also the volume controls are overshooting which makes it hard to control.
Are there any improvements that can be made ?

The sound cuts off before reaching the lowest volume on the volume control. Is there a way to adjust the scale ?

[cam (cam-linux-kernel-bugs)]

The 13s verbs aren't in a good state and are in no condition to attempt
any sort of inclusion into the kernel IMO. You're going to have to
experiment with applying the 13s verbs in debug mode. Look for sycxyc's
posts for some potential insights into this.

As far as the quality, this may be due to the verbs needing to be
cleaned up, the more advanced audio features of your laptop not being
supported by Linux, or some combination of both. For example, in the
case of the 2020 Legion, I've found that audio quality between Linux and
Windows is about equal if you disable Dolby audio in Windows. Dolby
isn't supported Linux AFAIK at this time.

I've failed to get the sound card running in the windows guest and created a separate report for the ACL711 in bug #213641

[cam (cam-linux-kernel-bugs)]

It can be a lot of effort figuring out how to force Windows to use the
correct drivers for the device. Unfortunately at this stage, there is no
fixed set of steps since it seems to at least partially vary between
laptop models.

I performed another system update, and later on, reboot my system, now the sound cards are working perfectly fine.

This behaviour I observed was on the below kernel version:
~~~
kernel-core-5.13.0-0.rc5.20210611git929d931f2b40.42.fc35.x86_64
~~~

Now, I have this version, which resolved the issue:
~~~
kernel-core-5.14.0-0.rc0.20210701gitdbe69e433722.6.fc35.x86_64
~~~

linux-5.12-legion-sound-0.0.9.patch - Improved 13s Gen 2 support

Big thanks for Vince Morel for providing cleaned up verbs for initialization on the 13s Gen2. We're down from around 400 to just 14!

13s Gen2 users, please test. Please ensure that audio still works after unplugging headphones and report on quality as well. When comparing audio quality, please disable any advanced audio features (such as Dolby) under Vantage as such features are unlikely to be supported under Linux anyway (Dolby is unsupported for example).

Now for some bad news. Between my job and family, I really don't have time to keep trying to figure out how to get this work into the kernel especially when I don't even get any responses back at all. Probably tonight, I'll re-share this patch as a patchset of 3 in case anyone else wants to give it a shot, but I really just don't have the time anymore.

And for good news, I'll likely have a 2021 Lenovo Legion at some point in August (the order has been placed since early July, but who knows when I'll actually receive it due to all the supply issues). Once I have that, I'll do this one more time and try to get sound working there as well.

Once I can start the process with the 2021 Legion, I'll finish up the documentation work that I have in the pipeline. I'll document the process as I go through it again to make sure all is complete.

[waterproof93 (waterproof93-linux-kernel-bugs)]

Just installed the latest patch for 13SGen2.

Firstly, applying the patch linux-5.12-legion-sound-0.0.9-003.patch leads to some errors :

patch -p1 < linux-5.12-legion-sound-0.0.9-003.patch

patching file sound/pci/hda/patch_realtek.c
Hunk #1 succeeded at 6352 with fuzz 2 (offset -6 lines).
Hunk #2 FAILED at 6573.
Hunk #3 succeeded at 8145 with fuzz 2 (offset -27 lines).

2 out of 4 hunks FAILED -- saving rejects to file sound/pci/hda/patch_realtek.c.rej

So I directly applied linux-5.12-legion-sound-0.0.9.patch and was able to compile and install with no error.

The speaker sound is definitely better, the overshoot on the volume control is manageable.
Its hard to compare to windows because of Dolby, but its close.

The sound works after unplugging headphones (tried it multiple times).
The headphone sound still has some cracking noise and the bug on the volume control reappears (at least from what I tested). The sound on headphone is still pretty good.

I noticed a bug, rebooting the computer with an HDMI cable plugged in removes completely the sound card. This bug was also present in version 0.0.7 of the patch.

[cam (cam-linux-kernel-bugs)]

What is the volume overshoot you're talking about? Probably missing the
verbs to set something up there.

Same goes for the HDMI probably... I hadn't thought to test even my
laptop against HDMI as I never use it and don't really have a convenient
way to test.

Not sure what the problem with the patches is... I tried all 3 in order
last night and they were fine.

I think HDMI should not rely to those verb, probably another bug here. :) I will test it with hdmi, I admit I did not test hdmi connection (but I can with my 27" monitor)...

[cam (cam-linux-kernel-bugs)]

But the HDMI issue wasn't in 0.0.8? Probably some re-initialization is
missing with only these verbs.

Basically the bug is when you try to change volume (increase or decrease) rapidly after about the third tap, the volume goes directly to the max (or min depending on the direction).

Therefore, it's hard to get to the volume that you want.

This seems to only happen using the laptop keyboard.
With my mechanical keyboard plugged in I can change the volume without hiccups.

I don't know also about the patch issue.
I'm patching against the same kernel (5.12.14) every time.

I never tested 0.0.8, so this bug probably applies to it also.

[cam (cam-linux-kernel-bugs)]

What about when you change the volume using a software slider, does it
happen then?

I remember some of the verbs for the Legion/Yoga were related to volume
control. Maybe this is what they were for?

I'm not sure what you mean about a software slider.
There is no issue when sliding the volume using the gnome panel for example.
It's smooth, every increment on the volume works and I can stop anywhere on the slider.

[cam (cam-linux-kernel-bugs)]

Sliding the volume control in the Gnome Panel is exactly what I mean.
Thanks for letting me know.

Some update on de Legion 7 16ACHg6 (AMD Ryzen 5000), I finally got the QEMU VM working, the IOMMU groups were really bad grouped for the sound card. But started and got the HDA verbs. But still no sound, in the VM is also no sound. The Cirrus Logic amplifier needs to be initialized on this board. Got the driver but the VM doesn't pick it up. After some searching in the drivers it seems that this chip is controlled by I2C/GPIO through ACPI.

Decoded the DSDT table in ACPI and found the following:

Is there anyone that can help me from here on? Now I've no idea what to do, how to set the GPIO pins of this device from linux, maybe that works. There are also some init sequences and blobs from the Cirrus Logic drivers. Or can this be debugged from Windows in any way?

[cam (cam-linux-kernel-bugs)]

It seems everyone who's done this so far (including myself) had to
really work at getting Windows to use the correct driver for the device.
Likely, you'll have to do the same.

I had to go into the device manager and figure out how get things
working. I have some notes in this bug in what I had to do, others had
to do similar steps but not exactly the same.

Under my branch, I have notes on the steps I was able to use for the
2020 Legion:
https://github.com/thiagotei/linux-realtek-alc287/tree/cameron/lenovo-legion

Take a look at the "Getting sound working under Windows" section.

I haven't worked on my branch for a while because I'm waiting to repeat
this process again once I have my 2021 Legion. Unfortunately, I am
likely cancelling my 2021 Legion order soon as they've pushed the ship
date out to many months (*after* customer service confirmed I'd have it
in August or September) . I'm just waiting to hear back for confirmation
on the new shipping date from Lenovo's customer service.

Hi Cameron,

I already did that step to make sure that the Lenovo drivers are used. I just reinstalled the drivers but still no sound from the VM. I also really hope that is just a driver issue in Windows so that this can be fixed sort of soon.

I already start JCS QEMU as mentioned on your link. I've only one warning on startup is that the device cannot be reset, I've no idea if that is the culprit at the moment.

[cam (cam-linux-kernel-bugs)]

The device cannot reset isn't a problem. Occasionally, when
experimenting with verbs, you can wedge the sound card hard enough that
even restarting your laptop won't cause it to recover. You'll have to
fully power the laptop off and then power it back on before it will work
again. I suspect this is due to the device not being able to reset, but
even in my tons of testing, this happened only a few times.

Thought i'd reinstall linux to see if there were any changes with this Yoga Duet 7i. Still no sound with the newer kernels but 5.4.88-1-lts with Arch "Arco"linux does works every time. Microphone does not work. Why it works in 5.488-1-lts and not newer is beyond me. Why devs haven't compared the two and fixed it is also puzzling.

[cam (cam-linux-kernel-bugs)]

Updates:
Both of the 2021 Legion's (the AMD based Legion 7 16ACHg6 and the Intel based Legion 7i 16ITHg6) have sound issues under Linux.

Sound doesn't work at all under the AMD based 16ACHg6, and sound partially works under the Intel based 16ITHg6.

In the case of the Intel based 16ITHg6, sound works until you suspend to memory. Plugging in and removing headphones doesn't affect speaker output (so far). Probably the BIOS initializes the amp at book, but not at resume. For now, I'm using hibernate instead of suspending to memory.

Both laptops appear to have Cirrus Logic CS35L51 amplifier chips. There is presently no Linux support for this chip, and no publicly available datasheets as of yet. However, a driver is currently in the works for the CS35L41:
https://www.spinics.net/lists/alsa-devel/msg129286.html

So maybe we'll eventually see support for the CS35L51.

This means the audio output issues with the 2021 Legion lines are unrelated to this bug or at least the ongoing work that has occurred under this bug. I will eventually update the document to reflect the state of audio are the 2021 Legion's and what we present know here:
https://github.com/thiagotei/linux-realtek-alc287

Huge thanks to Marcus Aram who discovered the amplifier chip and its model and has been working towards getting this resolved.

In short, { 0x4XX, 0xYY } is equivalent with { AC_VERB_SET_PROC_COEF, 0xXXYY }
and { 0x5XX, 0xYY } is a combo of { AC_VERB_SET_COEF_INDEX, 0xXXYY }

For what is worth, here eare the verbs. These are from 16ACHg6 Legion 7 2021.
Got them from running a Windows VM with IOMMU PCI passthrough.

These only trigger the RGB lightning on the keyboard if you select the light
modus that responds to sound.

Hope that some can get some stuff working on this machine.

linux-5.13-legion-yoga-14ITL5-sound-0.0.10-001.patch

Adds speaker output for the 2020 Legion and the Yoga 7i. This is based against the Linux 5.13 series and incorporates Takashi's suggestions.

It compiles, but I haven't been able to test this. I might be able to get ahold of the old 2020 Legion for testing later this week (I'm not on the 2021 Legion 7i).

Please test and please test with headphone removal on the 2020 Legion.

Adds speaker output for the 13s gen2. This is based against the Linux 5.13 series and incorporates Takashi's suggestions.

This is still in a separate patch as it seems volume control (using keyboard shortcuts I think..?) are a bit wonky so unsure if this will eventually be included if this remains unchanged.

[accounts (accounts-linux-kernel-bugs)]

I have tested the patch from comment 387 on a humble Yoga 7 14TL5 (not Legion, BIOS version F5CN40WW & F5CN49WW) and I get sound out of the right speaker only (thank you!). I have also tried plugging and unplugging a jack and that switches correctly back and forth between headphones and speaker(s).

linux-max.patch - Based on the 0.0.10 with fixed Yoga 7i support

Max was able to get both speakers working again. Here is his patch.

I was able to test the 0.0.10 patch on the 2020 Legion, and both speakers work. Not sure why 0.0.10 broke right speaker output on the Yoga when sound initialization is so similar between the 2 modals...

When I have some time, I will try some of Max's changes against the Legion.

It looks like this patch will set both speakers to the right channel.

I can assure you that both speakers are working independently with the patch (I tested it on the hardware with `speaker-test -c2`). But I also see why you say that. According to your gist document it should have been 0x1a in line line 8223 of attachment 298363, right?

[cam (cam-linux-kernel-bugs)]

sycxyc,

Did you try patch 0.0.10? I converted the "0x20, 0x4b0, 0x20" lines to "0x20, AC_VERB_SET_PROC_COEF, 0xb020" and this seemed to break right speaker output on the Yoga 7i.

Strangely, this didn't cause problems for the Legion, but I still want to try some of Max's changes to see if there are any differences.

Right. When using the verbs in the patch on my hardware, both speakers only have sound when `speaker-test -c2` tests "Front Right".

I replace "0x20 0x4b0 0x20" with "0x20 0x400 0xb020" and there seems to be no problem. (I only used applyverbs.py to test it.)

On a Yoga 7-14ITL5 Ideapad (82BH) here. The patches in this thread are for this device too?

Installed a clean ubuntu 21.04 and dist-upgrade. I then tried using the 'linux-max.patch' based on comment 282. That is correct in how to use this patch or is this a kernel patch? If it is just a sound patch, I had no change at all as to speakers working. no sound at all from them.

thanks for all the work you all are doing to try and get these devices properly working.

[cam (cam-linux-kernel-bugs)]

No, you need to apply this patch against kernel source and compile your
own kernel. Once the last issues are ironed out, I'll work on getting
the patches merged.

little modification to the `linux-max.patch` to fix sound for Legion 7i, S740, Yoga 9i

Beware of a misunderstanding. With patch 0.0.10 alias `linux-5.13-legion-yoga-14ITL5-sound-0.0.10-001.patch - correct patch` only the right speaker was working for me, the left one did not on the `Yoga 7 14ITL5`, which is how my model is called according to the back plate. It also has stickers on it, calling it a `YOGA 7i`.

I restructured the patch code a little and there was this comment `set right speaker Yoga 7i.`, but that was not sitting in the middle of the code block: The code block for the left speaker was shorter, so that I compared line by line what was missing and finally copied the difference from the right speaker to the left. I compiled the kernel with that and tested it on my hardware and it works - on a Yoga 7i that is.

The gist document from @sycxyc gives me a better understanding of what the code does and by the looks of it: `set the speaker` and `activate speaker` for both channels. But there are twopossibilities to `set the speaker` in the document and one is dedicated to the Yoga 7i only. Both possibilities are implemented in the patch in the same code block, so that changes for one model can influence another and I made a mistake, which could be a problem with other models: The attachment 298363, line 8223 should have been `0x1a` instead of `0x2a` to select the correct speaker before activating a speaker.

Attached is a patch called `linux-max-untested.patch` with the little change I mentioned. It should fix problem with other models and it should still work with the Yoga 7i. However it is untested, because I currently have no time to compile the kernel again.

Have fun and good luck.

Hi

I installed Ubuntu 20.04 on my Lenovo AIO A540 24ICB and my internal speakers doesnt sound.

I get sound using ext speakers connected to the audio jack .

I think that the problem si very similar to the problmes described here on other Lenovo machines but after reading the information here I am not sure which patch can I try.

Please can you help me to find which patch can I try?

I am attaching the alsa-info.txt form my machine.

Best regards and thanks in advance for your help

Are you already patching the kernel? Perhaps the right speaker is
already initialized and that's why it's working

[unmotivatedgenius+kernel (unmotivatedgenius+kernel-linux-kernel-bugs)]

I got the linux-max-untested.patch edited to be valid and then compiled. The speakers work with their correct channels. Wired headphones work as expected and sound switches back to the speakers after unplugging them.

I did the same(i suppose) as You, but I don't have sound on my Yoga 7 (15ITL5).
Could you tell me how did you build your kernel?

[sycxyc+kernel (sycxyc+kernel-linux-kernel-bugs)]

I recompiled snd-hda-codec-realtek.ko using attachment 298363 [details]. When I reboot the Yoga7i both speakers work fine as @Max described. But alfter S3 sleep wake up both speakers become right channel.

I changed `0x2a` to `0x1a` in line 8223 and updated snd-hda-codec-realtek.ko and then both speakers have the correct channel after S3 sleep wakeup.

I assume that the channel will be reset after boot, and the speakers will be conditionally activated after S3 sleep wakeup.

Unfortunately it's still on the low level and will find it's way in the standard kernel hopefully.
I have no insight on that yet, but am using one adapted C level patch suitable for my kernels.

If you want to step in and use the available patching offer you need to get familiar with: installing kernel headers and sources, install toolchain, compile kernel and kernel modules, apply patch to kernel module files, install changes modules and test and verify the result.
And that's mainly on C development level ...

One path of source for that maybe:
https://yoursunny.com/t/2018/one-kernel-module/
(but it depends highly on your linux system)

If you are not familiar with that keep your fingers away .... (it will cost some time and can't be explained in detail here since the guys working on that level spend much of their valueable time in solving the issues).

Alternatively you can try one of the offered hda-verb solutions. Maybe start reading with:
https://bugzilla.kernel.org/show_bug.cgi?id=208555#c241
(but you need to figure out what verb sequence is suitable for your system)

Thank you so much for your detailed response :) that all seems a bit beyond me. Was hoping it would just be a few lines in the terminal to make use of the work here. What's the "standard kernel"? Is that the core that all Linux distros build on top of? If that's the case I suppose it'll be a few years before people like me can use fully-functioning Linux on their computers T_T

As said you can give the applyverbs (1-liner) a try (not checking what hw you are on and which verbs maybe suitable for you):

Mainly yes, and if it's in then we have a goog chance that it will work for a lot of models in the future.
Here we are deep in kernel stuff and I doubt that you ever have done that under windows but you are nevertheless using it:)

[cam (cam-linux-kernel-bugs)]

Are you sure 8,223 is the right line? I don't see 0x2a, I see:
{0x20, AC_VERB_SET_COEF_INDEX, 0x26 },

Maybe you mean 8,221:
{0x20, AC_VERB_SET_PROC_COEF, 0x2a },

Or maybe you're not patching against against 5.13 like I am. :)

So regarding the volume control, I applied the patch 0.0.9 to kernel 5.13.5 and now the control seems to be working just fine !
I think this is a success.

I did had some error while applying the patch and at the end of the compilation but when I rebooted on the kernel everything is working good.

linux-5.13-legion-sound-0.0.11-002.patch - Support for 13s Gen2 and Yoga 7 15ITL5

If folks can confirm there's no volume weirdness with the 13s Gen2 laptops with volume control and if Yoga 7 15ITL5 support is confirmed working, I think we can merge the 2 small patches together to make one slightly less small patch.

IIRC, I think around 2 people complained about weirdness with the volume on the 13s Gen2... But if it's working for someone else, maybe there's a distro specific bug?

I can confirm that, after my little addition, everything works(on Yoga 7i 15ITL5). Both channels are correcly set up, and volume control is ok.
If it concerns, i have tested patches on Ubuntu 21.04, Kernel 5.13.12

This problem seems to affect HP SPECTRE x360 15-eb0675ng, too. This device has a Realtek ALC285 (sof-hda-dsp) sound card. Audio is working via line/headphone output, only. While a headphone is not connected, PulseAudio recognizes that nothing is plugged in, and when it's connected, it says headphone output. Alsamixer also confirms muting and unmuting of the integrated speakers, as well.
Sound is working perfect via line/headphone out, but speakers don't work.

We are sure that an integrated mini amp behind the sound card has to be triggered via special registers, too. We can confirm that it works under Windows, same thing as mentioned above.

You may want to apply your linux-5.13-legion-sound-0.0.11-002.patch for this device, as well. The diff looks like it would only take effect on the special Lenovo laptop, so I thought it would be a good idea to inform you about it. Maybe the patch would work 1:1 on the HP laptop, too.

If you need more information, I would like to support you as best as I can.

It seems that quite a number of models of this generation are affected, see also bug #213641 and the comments on other models in this thread. Perhaps a much more fundamental change is needed here, rather than looking at each variation individually?

Unfortunately, hey do not work and will not ever work. The 16achg6's

If I already have your full name on the above let list, let me know if you don't want to be included.

Hey Cameron,

thanks for your answer! The citation of the method would have been helpful despite the fact that I won't find a direct fix for my device.

Cheers,
Andreas

[cam (cam-linux-kernel-bugs)]

This is a work in progress. I haven't had the time to clean up and
correct the work I have in a branch.
https://github.com/thiagotei/linux-realtek-alc287

You can also search around for how to use JCS' Qemu.

This bug itself has most of the information on this approach.

Getting the hardware to work under the Windows VM may or may not be
difficult. On the 2020 Legion 7i, it took a fair amount of effort. On my
current 2021 Lenovo Legion 7i, Windows immediately recognized the
correct driver for the sound card.

Of course, this method may not work at all on your laptop. For example,
on both the AMD and Intel versions of the 2021 Legion, the method
doesn't work as the amp is a separate device on the i2c bus and
therefore isn't initialized by HDA verbs.

I don't know of any methods to capture communication over the i2c bus,
and I don't really have the time anymore to try even if I did.

Hello! Just want to say that I had to re-install my system.
So I patched kernel 5.14.3 with the latest patch and sadly I have no sound.
Note that if I apply my verb, sound is working, so the verbs still good.
I tried to replace in the 13S Gen2 part of the patch the "0xb020" address back to "0x20" just in case, but no more luck...
Could it be verbs from other soundcard in the patch? Can anyone with a Lenovo 13s Gen2 could try to patch a kernel with this patch?

[cam (cam-linux-kernel-bugs)]

Was the latest patch tested on your previous install?

This is very unfortunate as this patch appears that it just made it into

Aaaarrrg, I was overloaded and cannot make some test... I made some test yesterday, tried to compile 5.14.3 two time (after tweaking the patch file) but did not have any good result. Maybe I could try with another kernel or maybe it's a problem on my side when compiling but I doubt as it worked with my old 5.12.3 kernel (but it was the old patch with just the verb for the 13s). I will download the other patch version just to try and see, just a little time consuming to wait the kernel to be compiled each time! :)

Just an update. I compiled the 5.14.3 kernel with the last patch BUT I replaced all the "verb" in the 13S section with the one in the .009 patch (the one with 0x20,0x4b0,0x20) and it's working!!! So it seems replacing "0x20,ac_verb_set_proc_coef, 0xb020" with "0x20,0x4b0,0x20" made the patch works for the 13s... Weird...
That's the only thing I changed in the patch file...

[cam (cam-linux-kernel-bugs)]

Well, a patch won't be accepted with the verbs like that.

Maybe you can try something else and/or someone else has some insight on
this. I have no way to test this on my end.

Both must be identical from the code perspective.

But, looking at the verb sequence there, I doubt whether the 0xb020 call is really correct. If it follows the similar pattern as others, it should be rather setting the COEF index 0x26 instead, i.e.:

That make sense! I translated this into simple verb to test on a config with no sound and it works.

This is against the latest Torvald's tree, but applies against 5.14.11 with a minor offset.

There are no patches to get sound working on the 2021 AMD Legion 7. On
that laptop (and it's Intel cousin), there's a Cirrus Logic amp chip
that needs to be initialized over the i2c bus, which is very different
from the approach here.

Hopefully we'll eventually see a driver from Cirrus Logic.

Great! You beat me on this one! That's perfect! As I previously compile my kernel with this moded line and it worked, I guess we could now say it's working for sure! Great team work!

Hi,

I sent an RFC about Legion 7 16ACHg6 laptop, which lays out the architecture for how to configure the Cirrus Amplifier.

https://lkml.org/lkml/2021/10/8/344

As soon as we get some direction from Mark Brown and Takashi Iwai we will be providing support for that laptop.

Thanks
Lucas Tanure

[cam (cam-linux-kernel-bugs)]

Hello Lucas,

Ecstatic to see this moving along! I'd love to do what I can to ensure
that the Lenovo Legion 7i 16ITHg6 (the Intel counterpart to the 16ACHg6)
is supported by this as well. I suspect it wouldn't be substantially
different to support the 16ITHg6.

I don't have a lot of time these days, but I'm happy to do what I can there.

Thanks!!!

Hello there,

i have a new Thinkbook S13-IML and expierience the same sound issue under Manjaro. As i am still a beginner with linux, i am not totally sure if i understand the previous posts correctly - has this issue been solved and will this solution be available for Manjaro in the foreseeable future?

I was already going to the return the besides the sound and microphone issue flawlessly working machine. Thanks for your reply.

[cam (cam-linux-kernel-bugs)]

If the S13-IML is a model of 13S, then eventually sound will start
working as the patches make it into your distros kernel.

Can you run "alsa-info" and provide us with a link? That way I can
verify if there's a chance your sound will fixed by these patches.

Googling for "S13-IML" led me to this:
https://www.notebookcheck.net/Lenovo-ThinkBook-13s-IML-20RR0003GE.503100.0.html

Did you make a typo?

Hello,

Cameron Berkenpas can you tell if current fix will work for X1 Nano as well ?
X1 nano runs ALC3306.

full spec: https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_X1_Nano_Gen_1/ThinkPad_X1_Nano_Gen_1_Spec.PDF

Thanks,
Kind Regards, George.

[cam (cam-linux-kernel-bugs)]

I'm guessing probably not. The issue goes beyond supporting the ALC3306
(which is really just an ALC287). Linux already supports this codec (and
probably for quite a while too). The issue is that these newer laptops
also need their amplifier chips initialized to enable speaker output.

All of the laptops whose support were added with these patches had
different initialization sequences.

Then there are the 2021 Lenovo Legion 7 laptops (both the AMD and Intel
models). These have amp chips that must be initialized through an
entirely different process.

If the X1 Nano can have its speaker output enable through an hda verb
initialization sequence like the laptops supported in these patches,
then the same technical process could be used to reverse engineer support.

The PDF linked says the X1 Nano has Dolby Atmos just like the 2020
Legion 7 which makes me hopeful that the same process could be used.

However, there's no way to know with any certainty if this would work
without having the laptop in hand and trying it.

I still haven't been able to complete the documentation on how to
perform this process  due to a pretty severe lack of time for the past
few months, but I'll get to it eventually.

Do you already have an X1 Nano or you're just considering getting one?

I really like Lenovo's hardware... I just really wish they'd be more
helpful. I get that they don't want to provide technical support for
Linux across their entire lineup, but I think all that most/all of us
want is working hardware and not any sort of software support.

I made a typo, i was talking about the Thinkbook 13s - and could resolve the issue. Installing sof-firmware and switching to the kernel 5.15rc3 made the sound working.

Are you sure it's rc3? It seems even rc5 doesn't have any of the patches
I submitted. "uname -r" should provide the exact version (if you didn't
already know).

5.14.12 has my first patch, but does not yet have the 2nd patch to
correctly enable speaker output on the 13s gen2. I only submitted the
patch patch a week ago so it takes a bit of time to trickle down.

I'm not familiar with sof-firmware, but it seems to include firmware
needed to get audio working on some Intel systems. Maybe someone else
with a 13s Gen2 can confirm if that firmware alone is enough to get
audio working once we confirm the kernel version. Now I'm really curious!

[erazerhead99 (erazerhead99-linux-kernel-bugs)]

I am sure. Kernel 5.15rc3 on Manjaro. I am not sure if the installation of sof-firmware or the Kernel made the difference, will report back after testing.

Hi,

I've done my best to read through this thread, so I apologize if I've misunderstood. But as far as I understand the 2021 AMD Legion 7 has amplifier chips that are currently not supported and no current information exists as to how they operate?

I have an AMD 2021 Legion 7 and can help out if anyone is allocating time to this issue. Unfortunately I'm not a driver/kernel developer, but I can run scripts, retrieve information and test potential fixes.

I do appreciate the work that has been put into the other models!

[cam (cam-linux-kernel-bugs)]

I have great news for you. Lucas Tanure (who has posted on this bug
about this recently) is working on this right now:
https://www.spinics.net/lists/alsa-devel/msg132632.html

His work is still in the very early stages as there's back and forth to
determine the best way to implement support for these chips. I think
we're still a ways out from working support, but at least things are
moving in the right direction.

This bug has gotten very long, and I also feel like this is really a
separate issue. Would it make more sense to start a new bug for tracking
the support of the Cirrus Logic cs35l41 for laptops?

And this isn't technically a bug. Can we file kernel bugs that are
actually driver (feature) requests?

Cameron,

I already have x1 nano, running fedora 34 with sway.

modifying modprobe with:

options snd-intel-dspcfg dsp_driver=1
options snd-hda-intel model=thinkpad

enables audio out, but mic is not working and audio out is horrible with constant static in background.

I will gladly contribute in reverse engineering, but do not really have any prior knowledge in that regrade.

Currently holding RHCE and done lot of tinkering with swaywm/i3wm hope it helps.

Thanks,
Kind Regards, George.

Hi,

It will take a few weeks for sure. Because this is not my top priority laptop to support.
I hope that by the next start of the year will be done, but that depends on how the maintainers review my code.
The last comments from Takashi are complex and require changes that I don't know yet how to do, but we will get there.

I can also confirm that sound is working on the thinkbook 13s gen2 on 5.14.2 on arch with sof-firmware installed and no other patches applied.

[waterproof93 (waterproof93-linux-kernel-bugs)]

I'm just reporting, sound is working on newest kernel from Fedora, on ThinkBook 13S Gen2:
5.14.12-200.fc34.x86_64

No patch applied, no other firmware or tweaks.

Was the newest patch merged on the kernel?

[cam (cam-linux-kernel-bugs)]

The 13s fix went out recently and made it into the latest round of
kernel updates (ie, 5.14.14).

It's probable that this made it out into Fedora's kernel, especially if
updated relatively recently.

George,

I haven't forgotten about you and so finally I've made updates to the
documentation:
https://github.com/thiagotei/linux-realtek-alc287/tree/cameron

If you're up to it, hopefully that will get you on your way to debugging
this issue.

It's also possible this won't work for the X1 Nano... From your
alsa-info, we might be able to see if you have any Cirrus Logic amp
chips to worry about it. But the fact that it has the ALC3306 makes me
hopeful.

To everyone,

I've been really busy the last few months so it's been really hard for
me to find the time to work on this. These updates are still in my
branch as I'm sure there's more to cleanup. If you come across typos,
grammatical errors, things that need to be clarified, etc feel free to
let me know (either on through GitHub or you can even email me.

Would it be possible to add the IdeaPad/Yoga Slim 9i (0x17aa, 0x3834) to the list where the ALC287_FIXUP_YOGA7_14ITL_SPEAKERS quirk is applied? I tested this with a kernel based on 5.15.1 and it works perfectly.

[cam (cam-linux-kernel-bugs)]

I really don't have a lot of time right now...

But if you share your alsa-info, I could grab the more complete model
name of your laptop.

Or if you're up to it, you could submit a patch yourself:
https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html

You would need to subscribe and submit your patch to the alsa-devel
mailing list.

i've followed this thread since january 2021 and also here to confirm recent ubuntu kernel update solved this

i'm glad we held out, boys!!!!!

Lenovo Legion 7i 15 w/ Realtek ALC287

[brian (brian-linux-kernel-bugs)]

I can confirm that this change must have been delivered as part of Ubuntu 5.13.0-21. It fixed it for me. Lenovo Yoga 7 14ITL5 and ALC287 chip.

[mba380 (mba380-linux-kernel-bugs)]

I see that people with the ALC287 are reporting their sound issues to be fixed..
Can anyone with a legion 7 16achg6 confirm this? Unless you're already mentioned it, I couldn't find it..

I believe it has the same chipset, alc287.

Thank you.

[cam (cam-linux-kernel-bugs)]

The 16ITHg6 and 16achg6 are specifically not supported by any of these
patches as they require a very different approach. Lucas Tanure is
working on support and hopes to have something preliminary out early
next year.

Okay, great! Thank you!

Do you know how I can keep upto date with the progress (when he posts progress updates)? Is there like a list I can subscribe to or anything?

[cam (cam-linux-kernel-bugs)]

More or less.

He's posted on this bug 2-3 times IIRC.

He's also had some discussion on the alsa-devel mailing list to
determine the best approach to this driver. Not sure it's worth signing
up for alsa-devel just for that... It's a bit like drinking from a fire
hose. I'm only subscribed as I've submitted 2 patches so far snf may
submit some more.

Unfortunately I can't state that for newer versions since my boot stucks for higher versions (but that's not connected to this problem).

Not sure how exactly the patch is rolling out, but on my Lenovo-Legion-S7-15IMH5, I'm running Mint 20.2, switched to kernel 5.13.0-21-generic, and it's not working. I assume I should go through Cameron's guide on Github, unless I'm missing something and should just wait.

[cam (cam-linux-kernel-bugs)]

Not sure how Mint handles patching its kernels, but mainline 5.13
doesn't have my patch. I think 5.13 in Ubuntu does though.

My guide is useful for (theoretically) creating patches, however, that's
really not necessary in your case since the support is already there in
newer kernels. The latest 5.14.x and 5.15.x kernels do have the patches
so if you have some familiarity with building and running your own
kernel, building your own v5.14 or v5.15 would likely be the easiest route.

Hmm. Now that I'm thinking about it... Maybe there's a repo for Mint
with newer kernels available, which would certainly save you some
time/effort.

Or maybe you could ask the Mint devs to pull these fixes in.

Lucas, confirm that this patch is working on the Legion 7 16ACHg7. Feels little awkward that there is finally sound from the speakers :-) Thanks for your (and David) great work.

[cam (cam-linux-kernel-bugs)]

Looking at the patches, it seems that some adjustments will be needed to
make this work on the Intel model.

Marcus,

What tree or branch did you apply this against?

Did you need firmware as suggested in the patch notes?

I did checkout 5.16-rc2 and first patched with the patches from David https://patchwork.kernel<email address hidden>/ and after that the patches by Lucas mentioned here.

No, did not used any additional firmware. Sound is just working with these patches. Sound could be tuned by the firmwares from Lenovo probably.

Lucas,

Is this what you're looking for?

Here's my alsa-info as well:
http://alsa-project.org/db/?f=8200e38c38b74e3291b7f2e30b33e162a45b488e

You can see in both that instead of CLSA0100 like the 16ACHg6, the 16ITHg6 has CLSA0101. I think it's likely the same amp chip or very nearly the same.

Marcus brings up a good point. There are audio profiles available for different models of laptops. Is there any intention of supporting these? While it would be nice, I suspect it's unlikely and probably the audio quality is good enough without them.

[cam (cam-linux-kernel-bugs)]

There are only 2 patches in that linked series and it seems more are
needed. The 2 patches do get me to a state where some of the first
patches in Lucas' apply, but there are rejects for the last couple of
patches.

I'm patching against 5.16-rc2.

I suppose I'll try them against sound.git.

[cam (cam-linux-kernel-bugs)]

Turns out one of my patches was wrong. Now it all applies.

I've been busy today (and just generally) so all I've tried so far is replacing all instances of CLSA0100 with CLSA0101 and adding a quirk with my laptop's subsystem ID. Unsurprisingly it didn't work. I suspect I'll have a bit of time to look into it more thoroughly tomorrow though.

[pig.priv (pig.priv-linux-kernel-bugs)]

Just a heads up of my results so far:
Okay, so I compiled the latest Ubuntu unstable branch of 5.16-rc2 with a pull from Boonie: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound plus patches from Lucas: https://patchwork.kernel.org/project/alsa-devel/list/?series=585017.
(My fork over here: https://github.com/PIPIPIG233666/linux/commits/cs35l51)
I am using the Intel model as well and speakers do work out of the box but even with the amplifier fixes, I don't think the amplifier is working by any chance.

Correct, on the Legion 7i 16ITHG6 "works" out of the box, but you only
get the left channel (sounds like from both speakers too) as it seems
the 16ITHG6's firmware incorrectly initializes the amp chips during
bootup and only during bootup. Resuming from sleep results in speaker
output no longer working as there's no code to re-init the amps on the
16ITHG6 yet.

My work around from this has been to instead suspend to disk, which has
a lot of problems with the Nvidia GPU... so I run Linux in Intel
iGPUU-only mode. But with only a single audio channel, gaming isn't very
viable under Linux right now.

Additionally, in the ACPI dsdt, the amp shows up as CLSA0101 rather than
CLSA0100. Therefore applying the ALC287_FIXUP_LEGION_16ACHG6 quirk alone
to the 16ITHG6 is not enough to get it working.

I did try replacing all instances of CLSA0100 with CLSA0101 in the
patch, but that doesn't seem to work.

In my limited testing, find_comp_by_dev_name() in patch_realtek.c isn't
able to find any amp chips, which suggests to me that they're not being
detected before we even get to the realtek code. It seems all the values
in "spec->comps[i].name" are empty strings (and certainly don't match
anything like "i2c-CLSA010*:00-cs35l41-hda.*"

I'm not really sure how Linux detects devices via ACPI (or in general).
I do know there's some differences in regards to i2c on Intel Vs. AMD
(something like one has 2 i2c controllers where as the other has just
1), but I strongly suspect the kernel abstracts much of that away.

I have a NULL pointer dereference at alc287_legion_16achg6_playback_hook+0xec/0x1c0 after adding CLSA0101 to where CLSA0100 is, I don't know if you are having the same issue.

I don't have any NULL pointer dereferences.

Also, it seems there's been a new BIOS release since early September. I
doubt it, but I wonder if would make any difference. I'm hesitant to try
it in case if makes a permanent upgrade related to the amp chips that
would completely break my sound. Here's the BIOS info I have (from lshw):

I'm on the latest 39 BIOS and nothing has really changed. Speaker still partially works.

[cam (cam-linux-kernel-bugs)]

The cs35l41 modules aren't built in. Only snd_pcm is. Not that it makes
any real difference.

Originally I thought I was only getting left channel audio out of the
right speaker, but it seems I'm getting left channel audio speakers out
of both speakers. It's possible this is a pinctrl issue that's separate
from the cs35l41 amp support. If that's the case, it's likely fixable by
making pinctl changes.

We'd still have no audio resuming from sleep, but it would be an
improvement.

Can you confirm what your audio situation is, Weikai Kong? Are you
getting left channel audio from both speakers like I am?

It's typically an amplifier issue for sure, my android phone once had the same issue with the stereo speaker (right channel) broken and I had to write an amplifier HAL to enable the amplifier feedback.

Yeah, I have exactly the same issue as yours. https://www.youtube.com/watch?v=6TWJaFD6R2s this is the video that I used to test audio, btw.

[pig.priv (pig.priv-linux-kernel-bugs)]

Another thing I have to point out is that when I uninstalled Cirrus Logic Amplifiers from Windows the same thing happened as well.

I don't see 2 I2Cs controllers for the amplifier or things like that while at it.
The amplifier is connected to Intel(R) Serial IO I2C Host Controller - 43EA (\_SB.PC00.I2C2) on Windows. The other 43E9 (\_SB.PC00.I2C1) controller is for HID. Nothing is connected to 43E8(\_SB.PC00.I2C0) for me.

[cam (cam-linux-kernel-bugs)]

Well, I did make a tiny bit of progress.

Seems the option to enable CS35L41 amp support needs to define some
dependencies... But for now, we can enable them in the kernel manually.

You may already have it enabled, but the "i2c-multi-instantiate" module
is also needed. For convenience, the kernel option is simply
I2C_MULTI_INSTANTIATE.

Unfortunately, it doesn't quite work:
[ 1364.629567] acpi CLSA0101:00: GPIO: looking up 0 in _CRS
[ 1364.629582] acpi CLSA0101:00: GPIO: looking up 1 in _CRS

[ 1364.629732] I2C multi instantiate pseudo device driver: probe of
CLSA0101:00 failed with error -22

under drivers/platform/x86/i2c-multi-instantiate.c, we have:
static const struct i2c_inst_data clsa0100_data[]  = {
         { "cs35l41-hda", IRQ_RESOURCE_GPIO, 0 },
         { "cs35l41-hda", IRQ_RESOURCE_GPIO, 0 },
         {}
};

Maybe something about this doesn't quite work on Intel or at least this
model of laptop?

On another note:
When I first got this laptop some months back, the touchpad initially
didn't work due to some some mapping issues with GPIO on TigerLake. It
was quickly fixed:
https://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel.git/commit/?h=fixes&id=2f658f7a3953f6d70bab90e117aff8d0ad44e200

Maybe there's some more Tigerlake/GPIO issues to be sorted out? Probably
not; this is just a shot in the dark.

I did not do anything and I also have the following in dmesg:
[ 3.258973] I2C multi instantiate pseudo device driver CLSA0101:00: Error requesting irq at index 0: -22
[ 3.260295] I2C multi instantiate pseudo device driver: probe of CLSA0101:00 failed with error -22
However, I have nothing else. And you are right, the touchpad was fixed by that patch or that series of patches.

FYI, internal speakers are working on the Yoga 7i (14ITL5) in Elementary OS 6 (Odin, daily build) with kernel 5.11.0-40 (fresh install, no post-install patching).

[jenefer.marker (jenefer.marker-linux-kernel-bugs)]

Hello,
thank you for implementing the fix for the lenovo legion 7i. I just wanted to point out that when the audio volume is higher that a certain threshold (around 60%), the sound cracks or get distorted for some notes (maybe ones with high frequencies). I don't know if I'm the only one having this issue.
I am running Manjaro KDE on kernel version 5.15.7-1-MANJARO.
Thank you

[oreo639 (oreo639-linux-kernel-bugs)]

Thank you for the patch, Cameron Berkenpas.
However, my Yoga 7 15ITL5's subsystem device ID number is different from the one checked for in the patch.

For me `cat /sys/bus/hdaudio/devices/ehdaudio0D0/subsystem_id` returns 0x17aa384a

Editing the code to check for that causes the speakers to work.
The patch I used can be seen here:
https://github.com/oreo639/void-packages/commit/d59710b8b266200d6936e95fd1d9307e8e17132d

I'm not sure where this difference comes from or if this is normal, I'm not familiar with this so I was hoping you (or anyone else ofc) could help. Sorry for any trouble.

[cam (cam-linux-kernel-bugs)]

Seems you have a different revision of the laptop. Once thing I've
noticed is that different countries tend to have different subsystem
Ids, but it could also be a different reason.

That is correct. I have no experience with submitting patches to any of the kernel projects, but I have submitted a patch to a different project using patchwork in the past.

Can you please verify, that you have:

cat /sys/bus/hdaudio/devices/ehdaudio0D0/subsystem_id

- according to your ALSA it should be
Subsystem Id: 0x17aa3822
(the same as for Andrei Miculita ?)

to my understanding there's currently no patch for this device in the code.

I don't have that exact directory but I have the following:

Is there any way I can help with that?
I know almost nothing about kernel but I can extract whatever you need or maybe if you can point me to some documentation I can try to do something myself.

Maybe the available patch work also for your ID, since it's an ALC287 with at least similar settings:
But now it becomes difficult, you can try (but need a certain knowledge) about it:

1) Quick test: install hda-verbs, python3 and applyverbs.py. Load verbs.txt (see attaches above and maybe try different) and give it a try,
You find the necessary documentations in this thread.
sudo python3 applyverbs.py verbs.txt

2) If you are able to build a kernel then find in patch_realtek.c (makes only sense if 1) works)
SND_PCI_QUIRK(0x17aa, 0x3852, "Lenovo Yoga 7 14ITL5", ALC287_FIXUP_YOGA7_14ITL_SPEAKERS),
and add a line for your id: (0x17aa, 0x3822 ....)
hopefully adding the line is correct and need nothing more.

3) if 1) is not working you may try S3 mode (see comment #120 ....).
sudo dmesg |grep ACPI| grep supports
# may give you an indication if S3 is enabked on your device

4) There are maybe a handful of experts which are able to debug the correct hda_verbs (I do assume it can be solved with that on your device) out of the setup Cameron has described, but ....

But non of these options is an easy way and you need to do it yourself or find something with the same device helping you.
Option 1) can be done with some Linux experiences ....

I saw that oreo639 reported a similar case and was successfull with adding:

For compiling a kernel module that's a good doc. Start with:
Obtain the kernel headers and the compiler, and download the kernel sources ...

Hello all, I apologize if this comment is irrelevant but I think this would be a good place to ask for help as I'm quite new to kernel compilation.

I have been watching this thread for a little while and I'm not quite sure how I can make sound work on my Legion 7 16ACHg6. I tried applying the following two patches against kernel 5.16-rc8:

https://patchwork.kernel<email address hidden>/
https://patchwork.kernel<email address hidden>/

However, I got rejects for the second series and after I tried manually fixing them, I got errors during compilation.

I also tried applying Lucas' patches against sound.git (https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound) and that compiled fine but PulseAudio refuses to work.

Am I missing something? Thanks!

I have the same issue.
I have a Legion 7 16ACHg6 (82N6007CPB) which I'm testing under Ubuntu 20.04.3 LTS and 21.10 LiveUSB, and in both of them there is no sound out of the built-in speakers. Headphones are working fine though.

Hello again,

I've tried compiling kernel 5.17-rc2 (and rc1) now that the patches have been merged and I still can't get any audio on my Legion 7 16achg6.

The modules snd_hda_scodec_cs35l41_i2c and snd_hda_scodec_cs35l41 seem to have loaded properly so I'm not sure what the problem is. I have tried both PipeWire (my current choice) and PulseAudio, and neither worked.

A patch also exists for my device's subsystem id:

cat /sys/bus/hdaudio/devices/hdaudioC1D0/subsystem_id
0x17aa3847

patch_realtek.c:9131:
SND_PCI_QUIRK(0x17aa, 0x3847, "Legion 7 16ACHG6", ALC287_FIXUP_LEGION_16ACHG6),

I can confirm that this isn't an isolated case since someone left a comment on a blog post I made confirming that he's also having trouble.

Any support would be appreciated!

Hi Nikolaos, I am new to compiling the kernel and was attempting the same rc2 compiles/testing/fail (sans the lkml patches). Could you please share your kernel .config as I want to validate against mine. Thanks!

Hi,

No patches needed, only enable configs:

Hi Lucas, great!!

I build the kernel like this: (Arch Linux)

make olddefconfig
./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_I2C
./scripts/config --enable CONFIG_SERIAL_MULTI_INSTANTIATE

And install that kernel.

[i (i-linux-kernel-bugs)]

Hello all,

I recently bought a new IdeaPad (Yoga) Slim 7 Carbon and still can't get the sound fully working after trying different things in this bug.

My laptop has ALC287/ALC3306 + 2 CS35L53 (denoted as CLSA0102 in the DSDT) and 0x17aa3856 as subsystem id. There are 4 speakers on this laptop, 2 tweeters and 2 subwoofers. The tweeters can create sound but subwoofer is muted. Disable EAPD through HDA verbs will cause tweeter be muted (re-enable EAPD also only re-enables tweeters)

I applied the original "v6 8/10" i2c multi-instantiate patch (modified id to CLSA0102) and similarly modified and enabled quirk ALC287_FIXUP_CS35L41_I2C_2 on my device. From dmesg everything loaded correctly. I also tried to set the CS35L41_AMP_GAIN_CTRL to 17.5db according to the inf file I found in windows configuring speakers for this laptop.

[ 3.607141] cs35l41-hda i2c-CLSA0102:00-cs35l41-hda.0: Cirrus Logic CS35L41 (35a40), Revision: B2

However, I still can't get my subwoofer working. One thing I wonder is for both ALC287_FIXUP_CS35L41_I2C_2 and ALC287_FIXUP_LEGION_16ACHG6 there're no coefficient fix and only amp fixes. I wonder if it's possible coefficient fixes are also required in my case. I tried multiple coefficients (in this thread and in kernel) too but none of them made my subwoofer working. ALC287_FIXUP_LEGION_16ACHG6 with modification to support CLSA0102 also don't work.

I don't think it's firmware related as the hda config in cs35l41 bypassed dsp firmware.

Great thanks for the help!

Just curious, how do you know it's a CS35L53?

My laptop has a CLSA0101 and these patches don't work for me either. Lucas has informed me that this will be supported at some point. I've no idea what current the status is. I assume the CLSA0102 is likely in the same situation.

Perhaps the codec for the cs35l41/2 doesn't quite work our AMP chips.

(Digging through the Windows drivers, it seems I might have the CS35L51.)

To make your life a bit easier, linux-next seems to have all the up to date code:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

You'd still have to muck around the code to get your CSLA0102 in there, but it's probably a bit more convenient than dealing with the patches.

[tanure (tanure-linux-kernel-bugs)]

Hi,

Please do not change CS35L41_AMP_GAIN_CTRL from 4.5 db.
Without the firmware for the device, the laptop speaker has no protection, and a higher gain can damage the speaker.

Thanks
Lucas

[cam (cam-linux-kernel-bugs)]

Lucas,

Do the CS35L5* chips require firmware to operate? It seems the
CS35L41/2's do not.

And out of curiosity, does the CLSA0101 have the CS35L51?

Hi all,

New Lenovo Yoga Duet 7 13IML05 (2020) user here. The Duet 7 is a really nice, light and compact 13-inch tablet, ideal for triple-booting Windows, Linux and macOS. The only issue currently with this device is getting the ALC287 sound chip to work in Linux and macOS.

I confirm darnellkeithj's findings that the sound output (speakers and headphones) works out of the box with the Arch kernel up to and including 5.4.88-1-lts. I'm actually using Manjaro Linux for testing, which allows installing several kernels and switching easily between them. Older Arch kernels may be downloaded from the Arch Linux Archive at https://archive.archlinux.org/packages/l/linux-lts/ and https://archive.archlinux.org/packages/l/linux/.

Kernel 5.4.89 breaks sound output on the Yoga Duet 7 because of the following commit:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/diff/releases/5.4.89/alsa-hda-realtek-fix-speaker-volume-control-on-lenovo-c940.patch?id=1889f9ac9f9eb7f91ffc22e607a2e3db3db2e72e
For some odd reason, the Lenovo Yoga C940 seems to be using the same audio subsystem ID 0x17aa, 0x3818 as the Yoga Duet 7, so any quirk applied to the C940 will apply to the Duet 7 as well, even if it is not required. Reverting this commit fixes the sound output for kernels up to and including 5.4.98-1-lts. Kernels 5.x break sound output again, even with this commit reverted... So this is not an optimal approach.

However, I found an easy way for fixing the sound output (speakers and headphones) on the Yoga Duet 7. The cool thing is that it doesn't require compiling a custom kernel. Sadly, the fix works only for kernels up to and including 5.10.1.
Simply disable the snd-sof-pci driver and force the use of the legacy snd-hda-intel driver by adding the following two lines to /etc/modprobe.d/alsa-base.conf
"blacklist snd-sof-pci"
"options snd-intel-dspcfg dsp_driver=1"

With both solutions, the digital microphone won't work at all, as it requires the SOF firmware.
The mic is detected and works perfectly on newer kernels (> 5.9.x) when using the SOF firmware. The headphones work as well, only the speakers won't emit any sound.

Basically, you have to choose between having a mic or having a speaker.
No microphone is fine for me and kernel 5.10.1 is quite modern, so I could live with the situation for the time being.

I'll play around with the Realtek verbs in the next few days to find a real solution, as the above fixes are dead ends.

I'd be very glad to receive some input from the other Yoga Duet 7 owners.

Cheers for now!

Hi all,

Good news for Lenovo Yoga Duet 7 13IML05 owners!

The HDA verbs (and therefore the quirks) for the Yoga 7 work perfectly on the Yoga Duet 7 13IML05 after the following patch is reverted:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/diff/releases/5.4.89/alsa-hda-realtek-fix-speaker-volume-control-on-lenovo-c940.patch?id=1889f9ac9f9eb7f91ffc22e607a2e3db3db2e72e

Thus, writing a kernel patch for the Yoga Duet 7 becomes trivial:

With this patch, the internal speakers, headphones, headset mic and internal microphone all work on the Duet 7.

Now, I'm not sure how to get this patch to be merged, as reverting the patch for the C940 would obviously break sound on the C940. Why Lenovo decided to use the same subsystem ID (0x17aa, 0x3818) on both laptops is beyond me. I haven't been able to find another example of identical subsystem IDs for two different machines anywhere else in the "patch_realtek.c" file. At first, I thought that simply adding the quirk for the Yoga Duet 7 with the same subsystem ID might work, as the different DMI info allows to distinguish between both laptops. Well, that doesn't do the trick, so the only working fix right now is to revert the c940 patch.

Perhaps someone from the ALSA team would know how to deal with this odd issue.

By the way, no need to compile the whole kernel, compiling the 'snd-hda-codec-realtek.ko' module is enough. Backup and replace the module in /lib/modules/5.x.x/kernel/sound/pci/hda/ with the new module you just compiled and reboot to have working sound.

[cam (cam-linux-kernel-bugs)]

Probably the models of laptop each need their own set of verbs.

Hi, just wanted to confirm, adding these patches on top of 5.17-rc4 works for me on my 2021 Legion 7 (AMD). This is running Ubuntu 21.04. I grabbed the kernel source from the Ubuntu tree, as linked here

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17-rc4/

And built following the instructions here

https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel

In the editconfigs step you have to navigate in menuconfig to Device Drivers /
X86 Platform Specific Device Drivers /
I2C and SPI multi instantiate pseudo device driver

and select that module. Then Exit/Save the config and build. It takes a few minutes to build, but the process goes smoothly.

Thanks for getting this working!

I've tried with that kernel direct from kernel.org but couldn't find the SPI multi..., is there any previous step I'm missing?, I read something about a patch, but I don't know which one is ( I have the same laptop than you )

The patch in the comment I replied to, comment #539.

That's why I replied to that specific comment.

that's where I got lost, I can't find any .patch in that thread, how do I apply the patch?

I'm using this kernel:

And I can compile with no issues, but the patch is what I'm missing

[henry.hormaza (henry.hormaza-linux-kernel-bugs)]

well finally found the way to make it work in the legion 7 2021 AMD (16achg6)...

this is a short tutorial to build the kernel with the patch (I've done it on fedora 35):

1) make sure you have all the tools to build the kernel (https://fedoraproject.org/wiki/Building_a_custom_kernel):

* sudo dnf install fedpkg fedora-packager rpmdevtools ncurses-devel pesign grubby git

2) clone the kernel from github and checkout to v5.17 branch:

* git clone https://github.com/torvalds/linux.git
* cd linux
* git checkout v5.17-rc4
* git pull

3) get the patch and install it:

get the patch form this site: (top rigth corner "series" button):
https://patchwork.kernel<email address hidden>/

* git am Support-Spi-in-i2c-multi-instantiate-driver.patch

4) load your old kernel config

* make olddefconfig

5) change configuration at menuconfig as Howard Chu explained in his previous post

* menuconfig -> Device Drivers / X86 Platform Specific Device Drivers / I2C and SPI multi instantiate pseudo device driver ------> Enable this

6) build the kernel

* make -j 16

7) install the kernel

* sudo make module_install
* sudo make install

8) reboot and enjoy internal speakers

(if anyone sees a mistake or something that I did wrong please feel free to correct these steps)

Thank you to everyone who worked on this patch

[tanure (tanure-linux-kernel-bugs)]

Hi,

Yes, you are right. You don't need to get that series patch if you use the linux-next tree or just wait for the next linux kernel release.
Also, you could just:

$ make olddefconfig
$ ./scripts/config --enable CONFIG_SERIAL_MULTI_INSTANTIATE
$ ./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_I2C
$ ./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_SPI

Instead of using menuconfig step.

Thanks

hi Darin!,
First of all, thanks for sharing
I tried in ubuntu 21.10 your guide, steps 1 to 6 perfect, no problem at all, in the 7), when run: sudo make module_install, i have:
No rule to make target 'modules_install'. Stop.

Later when i reboot the laptop (a lot of times), i have a missing modules error and the boot stay crashed on a initframs prompt.

im missing to do something?.

Regards!

[darinsmiller (darinsmiller-linux-kernel-bugs)]

Hmmm, I too now cannot get past the "sudo make module_install" message:

   No rule to make target 'modules_install'. Stop.

I tried re-installing headers and relinking build & src directories as follows:

sudo ln -s /usr/src/linux-headers-`uname -r` /lib/modules/`uname -r`/build
sudo ln -s /usr/src/linux-headers-`uname -r` /lib/modules/`uname -r`/src

but no progress.

I confirm this guide works flawless on ubuntu 21.10 with this considerations:
 * The steps 3) and above, i run as root user (sudo su or su)
 * In the 7) step, as have been comented, the correct command is:
sudo make modules_install

With this tweaks no more freezes at the boot.

I have the same, just got it two days ago. Unforntunately even with installing the release candidate rc4 and rc5 of kernel5.17, the sound does not work. When going to sound settings it does not list anything as output devices.

I am using ubuntu 21.0 actually.

Any idea?

I also had plenty of issues setting the bluetooth connections to my keyboard, gnome-shell is consuming CPU like crazy etc - so seems like some kind of outside force is trying to keep this PC and ubuntu as far as possible :D

[ferkorol (ferkorol-linux-kernel-bugs)]

Here is another variant, now with RC6, works the sound and the nvidia drivers at the same time! (with some tricks):

A) FIRST TIME
1) install kernel build tools:
(https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel):

* sudo apt install libncurses-dev gawk flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf git p7zip-full

2) clone the kernel from github and checkout to v5.17 branch (Rather large, multiple GB's):

* git clone https://github.com/torvalds/linux.git

3)Make a 7z of the linux folder in a clear state
7z a linux-clean.7z linux

3) get the patch and let it in one superior level of the linux folder:

https://patchwork.kernel<email address hidden>/

A) FOR EACH RC RELEASE:
7z x linux-clean.7z
cp Support-Spi-in-i2c-multi-instantiate-driver.patch linux/
cd linux
git pull
git checkout v5.17-rc6
git am Support-Spi-in-i2c-multi-instantiate-driver.patch
make olddefconfig
./scripts/config --enable CONFIG_SERIAL_MULTI_INSTANTIATE
./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_I2C
./scripts/config --enable CONFIG_SND_HDA_SCODEC_CS35L41_SPI
./scripts/config --disable CONFIG_DEBUG_INFO
./scripts/config --set-str CONFIG_SYSTEM_TRUSTED_KEYS ""
./scripts/config --set-str CONFIG_SYSTEM_REVOCATION_KEYS ""
make -j 16
make modules_install
make install

The patch is mandatory to enable the sound in ubuntu, im tried without the path and the sound don't work. With this steps will do.
In order to make work the nvidia drivers in the 17-rc6 im just change in "more drivers" option of ubuntu, the current versión of the nvidia driver for another (511 to 470 for example).
Im using hybrid graphics mode in the bios.

Great discovery on enabling the NVidia drivers under Ubuntu. A side note for Kubuntu users, run:

  sudo software-properties-qt

Then toggle the driver version on the Additional Drivers tab.

A second note. In order to boot into discrete graphics mode, change the profile to "nvidia" either in NVidia settings or command line:

 sudo prime-select nvidia

Reboot into BIOS and select the dedicated graphics option. I assigned the following command to a shortcut key to boot reboot directly to BIOS:

  systemctl reboot --firmware-setup

Probably yes, but not sure you should trust and install a kernel hosted by just anyone ;-) I'm hoping that this patch will just soon find it's way to the official distributed kernels...

Thanks! I just tried this rc6 version on my machine, and sound plus nvidia drivers work fine with this. In addition to the described steps, I also did run a "make headers_install", to make sure that nvidia could compile it's module.

My machine: Lenovo Legion 7 16ACHg6 82N6 - Laptop 16" IPS 2560 x 1600 (WQXGA) 165 Hz - AMD Ryzen - with 3 external monitors connected and working (2560x1440).

I hope the patch gets propagated soon to a real release.

Hi guys,

This is my first time compiling a kernel (Legion 7 16ACHg6/Ubuntu 20.04). I followed these steps (checked out the v5.17-rc8 branch on git) but at the end I am getting this error at the last step, just before running sudo make install:

arch/x86/Makefile:154: CONFIG_X86_X32 enabled but no binutils support
sh ./arch/x86/boot/install.sh 5.17.0-rc8+ \
 arch/x86/boot/bzImage System.map "/boot"

 *** Missing file: arch/x86/boot/bzImage
 *** You need to run "make" before "make install".

make: *** [arch/x86/Makefile:278: install] Error 1

Any help would be appreciated

Hello @vpi

Before running "make install" you need to compile the kernel with "make". "make install" will install the compiled kernel, so you need to compile it first.

Hi Mark,

I should've been clearer in my last comment. I followed the instructions stepwise, which means I ran "make -j 16" before running "make install". And yet I was getting this error.

Hi vpi,

I would recommend to start fresh. What I would do is:
 1. Get into the kernel config with "make menuconfig", load the .config file from the "Load" button at the bottom.
 2. Exit the men...

Hi, I'm trying the new fedora 36, right now it has the 5.17.0 RC8, what should I do to enable the configuration without building the kernel? or is just that the RC8 don't have the patch yet?

I using Fedora 35 right now, I have the Galaxy Book Pro 360, but it has the ALC298 realtek chip. I tried this patch for the kernel within this bug report but still didn't work for me. Also, the kernel 5.16.15 still doesn't seem to have a fix or even 5.17.

However, this guide works: https://forum.manjaro.org/t/howto-set-up-the-audio-card-in-samsung-galaxy-book/37090

All I needed to do was install alsa-tools then run the script with the hda-verbs and after running the script (need to run it a few times) my audio works from my speakers and headphone. Without this, just audio works from headphone jack but not from speakers.

Additionally, after some time maybe 1 hr or so, or, if I exit a page with audio running, I need to re run the script again to apply the hda-verbs for my speakers to work.

Anyways, that worked for me and it might work for you. No need to mess with any kernel patches.

I already have my laptop with sound on fedora 35 (comment 560), I was talking about the kernel 5.17 that will be set in fedora 36. I don't understand how is merged every patch in a new kernel release.

Can somebody confirm what Kernel this is actually submitted to as a working solution without patches etc? I have been following for a long time and I was under the impression that the official 5.17 release had it incorporated?

I am currently using Manjaro Linux with the 5.17.1-3 kernel, and I still have no sound from the speakers.

I have not tried that mentioned ubuntu kernel.

With the source of 5.17.0-rc8+ and patches as described in this thread I do have audio but no brightness control. It does show a brightness bar on screen when hitting the keys, but no effect on screen itself.

Running linux mint 20.3, XFCE version, on Lenovo Legion 7 16ACHg6 82N6.

Note: before running this patched kernel, also my laptop screen sometimes stayed black after then screensaver/screen-lock was active. With the patched rc8 I have not seen that happening anymore. Running nvidia 510.54-* drivers.

Thijs.

[darinsmiller (darinsmiller-linux-kernel-bugs)]

Currently the 5.18-rc1 kernel throws an error when attempting install 510 drivers:

   dpkg: error processing package nvidia-driver-510 (--configure):
     dependency problems - leaving unconfigured

Subsequently, laptop refuses to boot discrete graphics when prime-select = nvidia. However, on-demand "works" (but no perf tests to support).

Regardless, brightness control have always worked in on-demand or "intel" (built-in vega) graphics mode.

As soon as I can fully install the 510 driver, I will check brightness controls and report back. (We need another thread for this discussion other this bug report... any suggestions?)

[cam (cam-linux-kernel-bugs)]

The issue appears to be that the Nvidia kernel module is failing to build and therefore you do not have working Nvidia support with this kernel. I'm not sure how you configured your kernel so I suspect you have one OR both of the following issues:

1. Nvidia's drivers do not yet support 5.18-rc1. Either Nvidia hasn't added support yet or your distribution's drivers are a little behind. Given that this is an rc1, it could be Nvidia that's behind.

2. Something in your kernel config is incompatible with the Nvidia drivers.

I strongly suspect it's #1 as others are having the same problem.

try:
lsmod | grep nvidia

You likely won't see anything.

At this point, it depends what's more important to you... Gaming or sound. You can revert to an older kernel or remove the Nvidia drivers for now. Eventually, newer kernels will be supported. In my experience, Nvidia usually isn't too far behind the curve on newer kernel support.

On a related note, brightness control with Nvidia in discrete mode has never worked for me on my Lenovo Legion 7i 16ITHg6.

Use aslamixer to increase max volume (command line tool). Some recent versions of pipewire tends to reset devices to very low levels and pavucontrol is not able to override the volume limiters. A couple of my systems required this method to fix sound volumes.

Looking at the model number, there's a chance it's compatible with the

attachment-14829-0.html

 From your alsa-info (thanks!), I see that your subsystem id is 0x3822
compared to the 0x1813 of the 15IMHG05.

In the root of the linux source folder/directory, open the file:
sound/pci/hda/patch_realtek.c

Find this line:
SND_PCI_QUIRK(0x17aa, 0x3813, "Legion 7i 15IMHG05",
ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS),

Next to that line (before or after doesn't matter), add your own line:
SND_PCI_QUIRK(0x17aa, 0x3822, "Legion 7i 15IMH5",
ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS),

If the ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS fix doesn't work for your
laptop, try theALC287_FIXUP_YOGA7_14ITL_SPEAKERS fix as well. Ie,
SND_PCI_QUIRK(0x17aa, 0x3822, "Legion 7i 15IMH5",
ALC287_FIXUP_YOGA7_14ITL_SPEAKERS),

But given the similarities between our laptop models, I strongly suspect
the 15IMHG05 fix will work for your laptop as well.

Looks like you're running linux Mint, which, IIRC, is based on Debian or
Ubuntu. For deb based distributions, you can build packages for your
kernel like this:
make bindeb-pkg

You only really need the linux-image and linux-headers (for Nvidia)
packages. To speed up the compile, you can pass in the -j option to
parallelize the build:
make -j$(nproc) bindeb-pkg

Seems you haven't installed the kernel source tree.

Obtain the kernel headers and the compiler, and download the kernel sources ...
sudo apt-get source linux-image-$(uname -r)
sudo apt-get build-dep linux-image-$(uname -r)

For compiling a kernel module that's a good doc. Start with:
https://yoursunny.com/t/2018/one-kernel-module/

... at the end there's only the need to replace one kernel module

Seems that your ALC287 has the id
0x17aa3847

Unfortunately having never done that before will need some learning time ...

The 2nd method would be to use the applyverbs method used also in one of our early trials (see comment 403).
Please make sure that the underlying "hda-verb" is installed, which may need some searching.
It simple fires the needed sequence to the devices as done in the kernel patch.

Good luck ...

[andreas (andreas-linux-kernel-bugs)]

So maybe for all not used to build kernel modules you may give that a try:
(sorry a comment describing that was 409)

# install hda-verb
# hopefully I have found the correct one
sudo apt-get install alsa-tools
# get applyverb.py
https://github.com/ryanprescott/realtek-verb-tools
# get the verbs txt file which does the miracle, i.e.
https://bugzilla.kernel.org/attachment.cgi?id=297545
# patch the chip:
sudo python3 applyverbs.py verbs.txt

then run a youtube video or any other sound stuff ...

[cam (cam-linux-kernel-bugs)]

According to your alsa-info, you have the already supported 16ACHg6
which is supported in the latest versions of the kernel.

There should be a repo you can add on your system to be able to pull the
latest mainline kernels. I don't have it handy at the moment as I've
been building/installing kernels myself since the 90's, but I'll try
find it and post it in a little bit.

The steps Woody shared are not necessary (no offense Woody), because:

1) Your hardware is already officially supported in newer kernel versions.

2) Our models of laptop have amp chips that are on the i2c bus and
therefore cannot be enabled via HDA verbs.

Hello everyone,

I really appreciate this thread and all of the solutions that have been produced for this issue. Thanks to everyone contributing, especially Cameron Berkenpas who has been very helpful to a number of users and the main driving force for fixes:)

Now to my issue: I own a Lenovo Yoga 7i 15ITL05 82AC with the ALC287. Currently it runs Ubuntu 22.04. LTS with the included 5.15 Kernel. Before I have run Pop_OS 21.04. and 22.04. With all these distros, the sound worked partially but never fully. The experience is the same as many other users here, where there would only be sound coming out the from the downward firing speakers, but not from the soundbar above the keyboard, which are the bass speakers judging by the tinny sound I get now. The sound works beautifully in Windows, since the lower end frequencies can be replayed.

Quite honestly, I've lost the overview over this thread and am not so sure which patch I should apply. I've tried manually update my Ubuntu 22.04. to the mainline 5.17 Kernel, which worked OS-wise but didn't change sound. My hope was that the sound patches have been included in that Kernel, but it seems they're only working for the Legion 7.

Could someone point me to the right patch or verbs that have to be applied for my Lenovo model in order for the bass speakers to work? Maybe someone has figured it out for this particular case?

Much thanks in advance.

I would try try 5.17. 5.18 only came out yesterday, and therefore doesn't even have any point releases so chances are reasonably high you'll run into bugs.

Additionally, I don't have the ACHg6. It's possible you'll need to specify which modules to load. In the likely event that 5.17 doesn't work, perhaps someone can provide information on what's needed there.

Possibly these steps will work:
sudo modprobe snd-hda-codec-cs35l41-i2c
sudo modeprobe snd_soc_cs35l41_i2c
sudo modeprobe i2c-multi-instantiate

[cam (cam-linux-kernel-bugs)]

There's no patch for your laptop yet.

Assuming your sound bar is initialized through verbs (I suspect it is),
you'll need to find the verb sequence yourself:
https://github.com/thiagotei/linux-realtek-alc287/tree/cameron

Once there's a working verb sequence, a patch can be created.

Your error message shows you're 5.13, which definitely doesn't have support.

Oh, sorry I was in the wrong one version cuz I tried reverting to the older one when nvidia didn't work anymore.

In kernel 5.17.0 the first command gives
$ sudo modprobe snd-hda-codec-cs35l41-i2c
modprobe: FATAL: Module snd-hda-codec-cs35l41-i2c not found in directory /lib/modules/5.17.0-051700-generic

while the other two give nothing.

Thanks for the quick reply and the pointer to the github tutorial. I've tried going down this rabbit hole but face numerous error messages when following the guide. Unfortunately I failed at building the js qemu fork. Maybe it fails because I'm on Ubuntu 22.04.? Anyways, I can't build it and thus can't even continue with the actual hard part.

Here's the output for the failed configuration of qemu: https://pastebin.com/Lfq5vPz6

Maybe it has to do with the dependencies? When executing sudo apt install build-essential && apt build-dep qemu-system-x86 it will says something along the lines of "choosing qemu instead of quemu-system-x86".

It seems the path to endian.h may have changed from
/usr/include/sys/endian.h to /usr/include/endian.h.

In the failing file(s), try changing it from:
#include <sys/endian.h>

To:
#include <endian.h>

Appears that these kernels are including these drivers. You might have
to figure out how to build your own kernel while enabling the necessary
kernel options yourself after all.

Hi everyone, with a thanks of your support!
I recently bought a new model of Yoga 7i 16" alsa-info is here:
https://pastebin.com/cPPAp0vq
 I so i do have 4 speakers with amp on which is not working in Linux (as everybody mentioned here on windows sound it is strong), the rest of the sound in headphones, bluetooth mic are loading fine . I've read carefully most of you posts, and I tested some commands in my Arcolinux system (Archlinux)

So with kernel 5.17 it is support for following modules...

[cristina223 (cristina223-linux-kernel-bugs)]

Thank you soo much!

[cam (cam-linux-kernel-bugs)]

Looking at your alsa-info, you don't have the CLS0100 amplifier chips, which is what those modules would enable support for. Your laptop is not supported by those modules and likely aren't supported at all.

Yes, tested, and I am enjoging my speaker now.�[U+1F603]�

[cam (cam-linux-kernel-bugs)]

Great!

Some probably silly questions:
1) Do both speakers work? Do you get left channel sound out of the left
speaker and right channel sound out of the right speaker?

2) After resuming from suspend/hibernate, does your sound still work?

3) What if you insert headphones and remove them? Does sound still work?
Try removing the headphones both while sound is not playing and while
it's not.

Given that this old quirk works for your laptop, I think all of the
above will be fine and I can work toward getting  this submitted.

Yeah, both the speaker and headphones work fine with correct channel.

And still work after resuming from suspend/hibernate.

Also fine after hotplug events, whatever it is playing or not.

Thanks for your patch a lot!

[Simon Barthel (zwackelmann100)]

Speakers are working for me now after installing the BIOS update from 2022-06-02.

https://pcsupport.lenovo.com/de/en/products/laptops-and-netbooks/legion-series/legion-7-16achg6/downloads/driver-list/component?name=BIOS%2FUEFI

I booted on windows, installed the update and after switching to Linux the speakers instantly worked without any problems.

Not sure if installing the update alone did the trick since I tried a lot before without success...

[cam (cam-linux-kernel-bugs)]

Songine,

Can you provide more info about your specific model? You should be able
to get that from running "lshw".

For the top of my output, I get:
version: Legion 7 16ITHg6

[andreimiculita+kern (andreimiculita+kern-linux-kernel-bugs)]

Quick update: it works! sort of...

I applied the first fixup (LEGION_15IMHG05), but it didn't work, and the second (YOGA7_14ITL) didn't either. But while booted from the kernel with the 2nd fixup, I decided to give it a quick suspend/wakeup cycle. After the wakeup, there is sound! But only from the left speaker. The sound is coming only from the left channel.

I will report back after retrying the 1st fixup, this time with a suspend/wakeup cycle.

I installed one of the newer kernel (5.18.3-1) on my 16ACHg6 with Manjaro and the sound now works beautifully. However, I also noticed that the speaker would stop working if I were to restore the machine from hibernation. So far the only workaround would be to restart the laptop to resolve the issue.

[cam (cam-linux-kernel-bugs)]

When you say hibernation, do you specifically mean suspend to disk? Or
do you mean suspend to RAM? Or both?

Great question and sorry I should have been more specific. In my repo experience, I meant to say it is the hibernation to disk, specifically to a swapfile, and not a swap partition (not sure if that matters but I figured might as well disclose in full).

I haven't tried to hibernate to RAM yet. I can give it a shot if you like.

[p.jungkamp (p.jungkamp-linux-kernel-bugs)]

I have news on the Lenovo Yoga 9 14IAP7.

The bass speakers are not working, but the soundbar works out of the box.

Here's the alsa-info on a default Arch Linux 5.18.3-arch1 kernel.
http://alsa-project.org/db/?f=88c18fe2a7e900cc9a1aef2b62d5a963460b7d74

Since my bass speakers weren't even recognized by the kernel (node 0x17 was 'not connected') I used hdajackretask to map the node as a Speaker.

This did not work either.

I tried to enable the 'ALC287_FIXUP_BASS_SPK_AMP' quirk in 'sound/pci/hda/patch_realtek' for my device.

This, especially the chained 'ALC285_FIXUP_THINKPAD_X1_GEN7' quirk, made the left bass speaker work. The right one remains mute.

Here's the new alsa-info after the patch and forceing snd-hda-intel instead of SOF.
http://alsa-project.org/db/?f=85bad6aac1448e944c730e4971ebd24672a67d86

Some fiddeling with alsamixer produced:

Without headphones plugged in:
- headphone jack mute switch does nothing (as expected).
- speaker mute switch mutes both soundbar and bass.
- bass mute switch mutes both soundbar and bass.
- adjusting DAC1 changes bass volume.
- adjusting DAC2 changes soundbar volume.

With headphone plugged in:
- headphone mute switch mutes headphones, soundbar and bass.
- speaker mute switch mutes bass.
- bass mute switch mutes soundbar.
- DAC1 changes bass and headphone volume.
- DAC2 changes soundbar volume.

I am not familiar with the signal path through HDA devices. Could someone explain or help me deduce the internal connections?

I can patch a kernel and probably write a fixup myself once I understand whats going wrong.

[cam (cam-linux-kernel-bugs)]

Please give that a shot. It's possible there's a new bug, or that it
wasn't tested against hibernate (just suspend).

I just tried all 3 options (running Xfce on Manjaro) and here are the results:
Hibernate (saves to HDD/SSD): FAIL - sound stops working upon resume
Suspend (saves to RAM): PASS - sound continues to work upon resume
Hybrid Sleep (saves to HDD/SSD and RAM): PASS - sound continues to work upon resume

My hypothesis is that Hybrid Sleep works because I didn't shut down the laptop long enough to drain the battery power in full, thus the resume works via RAM instead of HDD/SSD.

My conclusion is that there is a new bug where the sound stops working upon resume from HDD/SSD.

When did the 16ACHg6 first get support? 5.18? Possibly it was never
tested with hibernate.

I think that I found the relevant HDA verbs by sniffing on a Windows 10 VM.

Would someone else like to test the patch I wrote before can I try to submit it?

[andreimiculita+kern (andreimiculita+kern-linux-kernel-bugs)]

Can confirm it works! The ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS makes both speakers work on the 15IMH5, stereo sound. It does require a suspend/wakeup cycle first though.

On another note, the screen brightness controls on this device also have the same issue: they only work after a suspend/wakeup cycle.

It's usable though, better than nothing. Would this be good enough to be added to the main kernel? If that's ok I can also do it, more for the educational value than anything :) With appropriate credit to Cameron Berkenpas of course.

I'm in the same exact situation as Philipp (quoted below).

Lenovo Yoga 9 14IAP7, Arch Linux 5.18.7, no sound from woofers.

My alsa-info is here https://pastebin.com/UFneLZh7

I have a simple question: is there a way to fix this with the HDA verbs patch?
How do I find them?

Is this a kernel patch that fixes the yoga 9i gen7 issue? That would be amazing! Thank you Philipp!

One last request, I am not sure how to patch the kernel, would it be possible to have that patch in the form of a sh script that simply rewires the hda-verbs so I can test it (and implement it on each boot while the kernel gets patched)?

I was experimenting with a script like this:

hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x10
hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x0320
hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x24
hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x0041
hda-verb /dev/snd/hwC0D0 0x20 SET_COEF_INDEX 0x24
hda-verb /dev/snd/hwC0D0 0x20 SET_PROC_COEF 0x0041
{ ... and so on ...}

But I didn't get anywhere.

Hello Philipp.
I have the same Yoga 14IAP7 with no subwoofers sound.
I'm using Ubuntu 22.04.

I downloaded the vanilla 5.18 kernel ando could apply your patch, compile and install the kernel.

I still have no sound in my subwoofers, but the alsa-info output changed.

Do I have to blacklist any module or anything?
I haven't made any change in that regard.
My system is still loading the default intel sof drivers.

Could you provide a short list of steps?

Regards,

Gervasio

Hi all,

After several unsuccessful tries applying Philipp patch for Yoga 9 14IAP7, I realised I have a different lenovo sound device ID (0x381c instead of 0x3801).
I added to the patch the following line:

+ SND_PCI_QUIRK(0x17aa, 0x381c, "Yoga 9 14IAP7", ALC287_FIXUP_YOGA9_IAP7_BASS_SPK_PIN),

and the patch worked flawlessly.

I have a Lenovo Yoga 7i 14ial7 (some kind of exclusive german / swiss / austrian model) with Realtek ALC3306 which is also recognized as an ALC287 by ALSA. Bass speakers do not work so I just have a very weak sound from the bottom speakers.

I'm using Fedora 36 with the latest stable kernel (and parallel latest vanilla kernel hoping it will get fixed).

I have seen there are some patches in this thread and also in the latest Kernel-Versions, but I have a different audio codec ID so they don't apply.

My codec ID is 0x17aa3869.

I'm actually not a noob to linux but also not advanced enough to compile my own kernel and apply any kind of patch to it.

Is there anybody who can help me to get my speakers to work properly?

What kind of output is needed?

Thanks in advance and kind regards

Pascal

Hi Pascal,

You should try what I did: patch the kernel with your device ID.

I don't use Fedore but they have a tutorial for building custom kernels:

https://fedoraproject.org/wiki/Building_a_custom_kernel

You should follow those instructions up to the line which says "You can now make whatever changes / customizations you need before generating the rpms and installing them"

At that point you have to apply the patch.
In your case, you should edit in the patch file provided by Philipp the following line:

+ SND_PCI_QUIRK(0x17aa, 0x3801, "Yoga 9 14IAP7", ALC287_FIXUP_YOGA9_IAP7_BASS_SPK_PIN),

And edit your device id:

+ SND_PCI_QUIRK(0x17aa, 0x3869, "Yoga 9 14IAP7", ALC287_FIXUP_YOGA9_IAP7_BASS_SPK_PIN),

To apply the patch, you should get into the kernel source directory (the one containing the "sound/" directory) and execute the following command:

patch -p1 < your_edited_patch_file.patch

The patch application might fail, and you may end up with these three files in your sound/pci/hda/ folder:
patch_realtek.c (the partial patch)
patch_realtek.c.orig (the original file)
patch_realtek.c.rej (the rejected part of the patch)

In my own experience, the rejected part for this patch is the SND_PCI_QUIRK line mentioned above. In that case, you can edit manually the patch_realtek.c file and add that new line (there is a loooong list of SND_PCI_QUIRK entries near the end of the file, and the order doesn't matter, so you can just add it anywhere in the middle).
Keep in mind that the trailing "+" symbol should not be written when manually editing the source file (it's part of the patch tool syntax).

After doing that, you can go ahead and compile/install/try the new kernel (following the rest of the Fedora tutorial).

I can help if you get stuck. Send me an email.

Regards,
Gervasio

Hi Gervasio,

Thank you very much for your advice and that great manual.
I will try it as soon as possible.

Will that patch "stay" in my Kernel when I update to a new Kernel Version or do I have to apply that patch every time there is a Kernel update?

Thanks and regards

Pascal

No. If you want to update to a new kernel version you'll have to repeat the process.

[baipush (baipush-linux-kernel-bugs)]

Hello everybody

I can confirm it works for me too (thx Gervasio for pushing forward on me :) ).

How do we get the patches for all these different Lenovo models that have been touched in this thread into the original Kernel so that everybody can have them by default when installing their favorite distro?

[p.jungkamp (p.jungkamp-linux-kernel-bugs)]

I'd prefer to submit my patch as soon as possible myself to have the fixup/quirk mainlined. Other people can then just use a module parameter to enable the patch and check if it works properly for their devices. You can then submit the 'PCI_QUIRK' line for your hardware yourself. The module parameter should be an acceptable tradeoff until other devices' quirk lines are mainlined.

[gerva_98 (gerva98-linux-kernel-bugs)]

That sounds good. I hadn't thought of the possibility of a module option.
I haven't submitted any patches myself and suggested sending several PCI_QUIRKs together (at least the ones identified in this thread for Yoga 9i 14IAP7) because I don't know the delays involved in the submission process..

[baipush (baipush-linux-kernel-bugs)]

@Philipp

Why not submit all the patches from this thread? So it's easier for the maintainers of the kernel and there will be more devices supported by default in the future if somebody installs Linux on his Lenovo device.

To be honest I wouldn't even know how to submit a patch, I just learned compiling a kernel...I would really appreciate your help with this.

I would vote for it 100%! For sure this patch becoming a module in the next
kernel release would help not only Lenovo machines with this kind of audio
hardware.

I tested this on the Lenovo Carbon 14ACN6 and it did not appear to work. Card0 is a digital and card has subsystem ID 0x17aa3856, which is what I updated in the patch file.

[p.jungkamp (p.jungkamp-linux-kernel-bugs)]

A note on the 'model' and 'patch' options of of the 'snd_hda_intel' module.

The 'model' option can be used to apply a fixup written for another device.
You can check the fixups available for the ALC287 in the docs or in the
'alc269_fixup_models' array at sound/pci/hda/pathch_realtek.c:9551.
See https://www.kernel.org/doc/html/latest/sound/hd-audio/notes.html#model-option

The 'patch' option is similar, but way more powerful.
I used it to try a lot of configurations before I got the sound working.
See https://www.kernel.org/doc/html/latest/sound/hd-audio/notes.html#early-patching

I'd like to see the patch merged so people with devices for which the fixup might work can try the module option instead of compiling a patched kernel.

Something along the lines of
---
# /etc/modprobe.d/snd.conf

# use snd_hda_intel instead of snd_sof
options snd_intel_dspcfg dsp_driver=1

# enable the fixup
options snd_hda_intel model=alc287-yoga9-bass-spk-pin
---
should then work to apply the fixup until a PCI_QUIRK is added.
I'll give an update when I know when it's going mainline.

There were actually three problems with the bass speakers on the Lenovo Yoga9 14IAP7:
1. The Pin Complex node of the codec with NID 0x17 on which the bass speakers are connected reported itself as unconnected.
2. The bass speakers have amplifiers which need to be enabled via NID 0x20 of the codec. (similar to the Lenovo Yoga 7 14ITL5 fixup)
3. The driver connected the bass speaker Pin Complex to the DAC on NID 0x06 of the codec which has no volume control. (bass speakers always on max volume)

You can check whether your device is affected by problem 1 by checking the 'Pin Default' on 'Node 0x17' in the 'HDA-Intel Codec information' in your alsa-info.txt.
e.g. $ grep -A6 'Node 0x17' < alsa-info.txt
A 'Pin Default' that starts with 0x4, 0x5, 0x6 or 0x7 indicates and unconnected pin and thus problem 1 assuming the bass speakers are really on NID 0x17 on your device.

If your device is not affected by problem 1, the mainline fixes for the 'Yoga 7 ITL5' or 'Legion 7i' might already work.

[p.jungkamp (p.jungkamp-linux-kernel-bugs)]

https://mailman.alsa-project.org/pipermail/alsa-devel/2022-July/204315.html

The patch has been applied by a 'SOUND' subsystem maintainer.
It will probably be merged in the next merge window (Linux 5.20).

You can see the entry for the 'model' parameter in the patch.

[cam (cam-linux-kernel-bugs)]

The Lenovo Legion 7i Gen 7 (2022) model is now available in the USA:
https://www.lenovo.com/us/en/p/laptops/legion-laptops/legion-7-series/legion-7i-gen-7-(16-inch-intel)/len101g0018

If you have one of these laptops, please share your alsa-info here. I strongly suspect it has Cirrus Logic cs35l41 amplifier chips in it. Hopefully the more generic approaches will work here (such as cs35l41_fixup_i2c_two()).

Philipp Jungkamp's patch is already module in the new kernel release candidate linux-6.0-rc1.
For those who want to try it just compile the new kernel without patch and add in
/etc/modprobe.d/snd.conf

# use snd_hda_intel instead of snd_sof
options snd_intel_dspcfg dsp_driver=1

# enable the fixup

I have Yoga 9 14IAP7, running 5.19.2 kernel w the patch and modprobe;
$ cat /etc/modprobe.d/snd.conf
options snd_intel_dspcfg dsp_driver=1

This does fix the speaker out (volume/amp & bass) however the microphone input is no longer available.

Remove 'options snd_intel_dspcfg dsp_driver=1' and replace the second options line as 'options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin' to get the full (including microphone) support.

For people with exact Yoga 9 14IAP7 machine is not necessary to include
/etc/modprobe.d/snd.conf. The module is in the new kernel.
For those with different machine that want to try it, can use the snd.conf
at first then if you want to have the mic working you might have to patch
the kernel with your machine model.
I have an example of patch in my github

I don't see that result for Yoga 9 14IAP7. Speakers don't work properly without both modprobe lines. Microphone input ceased to work whenever "options snd_intel_dspcfg dsp_driver=1" modprobe is applied:

The TAS2563 works without the firmware (tuning file).
Documentation:
https://www.ti.com/product/TAS2553

However there is an android driver with firmware loading support.
https://git.ti.com/cgit/tas256xsw-android/tas2563-android-driver/
Or a mainline RFC:
https://lkml.org/lkml/2020/6/9/800

The bass speakers can be enabled with:
i2cset 3 0x4c 0x2 0
i2cset 3 0x4d 0x2 0

they are listening on 0x48 too, so in one turn:
i2cset 3 0x48 0x2 0

I don't know how safe it is to use it this way.

They have to be enabled after suspend, and if you plug in-out the headphone (only if auto mute is enabled).

I fall to my knees!
This helps: i2cset 3 0x48 0x2 0

In normal stereo 2.0 it sounds good now.
No bass in 2.1
In 4.0 bass, but sounds strangely delayed.

OK, that works! But what can I do to make this register (3 0x38 0x02 0) set automatically?
Does that have something to do with the power settings under /sys/bus/i2c/devices/i2c-3/device/power/*?

[fishsemxpinha (fishsemxpinha-linux-kernel-bugs)]

I've managed to get my Lenovo Legion 7 16ACHg6 speakers working on kernel 5.18.x by setting the following kernel configuration

CONFIG_SND_SOC_CS35L41_I2C=m
CONFIG_SERIAL_MULTI_INSTANTIATE=m

However, kernel 5.19.x seems to break it as with the same kernel config, the modules are loaded by do not work. Apart from the speaker, I'm having the same issue with the touchpad (works on 5.18, but not on 5.19).

Any ideas why it would work on 5.18, but not on 5.19?

I think you can run it with systemd after resume/hibernate/boot while I write a driver for it.

[dr.tikkel (dr.tikkel-linux-kernel-bugs)]

I disable the sound power management with the tlp.service and set the i2c-register with a own customboot.service after the tlp.service is started.

One thing to protect your speakers. It's a 6W amplifier so the default gain may be too much. I didn't dump the registers in windows yet, but in the limited sound on c940 issue ( https://bugzilla.kernel.org/show_bug.cgi?id=205755 ) they write about 11 dB for a 2W bass speaker.
I think that's a different amplifier, so the register values may not match.
Please add
i2cset -y 3 0x48 0x3 0x00
to your script until the windows dump is done.

Almost certainly your laptop doesn't have the _DSD entries needed to
properly get sound working.

Check dmesg for either of these messages:
dmesg | grep -i "Platform not supported -EINVAL"
or
dmesg | grep -i "Error: ACPI _DSD Properties are missing for HID"

For reference, see:
https://www.spinics.net/lists/alsa-devel/msg146157.html
https://bugzilla.kernel.org/show_bug.cgi?id=216194

I have the same problem with the Lenovo Legion 2022 Gen 7 (16IAX7). I
filed a support ticket with Lenovo a few weeks back, but when support
followed back they wanted to text during work hours, and I was too busy
to deal with that then and too busy to deal with it since. I think I may
actually have some time today.

If you have either message in your dmesg, I'd suggest filing a support
ticket. If enough people complain about these issues, it may compel them
to add the proper _DSD entries into a BIOS update.

There's no reason that Lenovo can't include this information in a BIOS
update. It does seem that going forward that the intention of Cirrus
Logic is for the vendors to include this information in the BIOS. For
vendors where this is not the case, likely what's happening is that
these values are hard coded in the vendor provided drivers or firmware.

It doesn't require them to touch Linux at all.

It should be relatively simple for them to add this information as
there's already an incomplete entry in the ACPI table as it is.

In the kernel bug linked above, I attached a hacky patch that gets sound
working on the 16IAX7... But it's a hack where I guessed and hard-coded
the values and these could physically damage your speakers if the
settings are too inappropriate for your model of laptop (including the
16IAX7). This is very much a USE AT YOUR OWN RISK scenario, and I
sincerely recommend against using my patches to avoid any possibility of
damage to your laptop. Furthermore, sound doesn't work after resume anyway.

Although it could be argued that if people start trying to use hacks
like these to enable sound under Linux for their laptop, vendors such as
Lenovo may need to issue BIOS updates to address this to avoid costly
laptop repairs.

Thanks for the info, appreciate it.
using grep i didn't find any of those messages though. so might not be the same issue after all then.

[cam (cam-linux-kernel-bugs)]

You could share your dmesg.

The other possibility is that the kernel doesn't include the
configuration (arch IIRC?).

My suggestion for both of you is to follow up with Lenovo support as I mentioned and see where that gets us. If enough of us take issue, they might be inclined to fix it.

Failing that, if enough of us are affected, maybe we can start a petition?

I bought the Legion 7 AMD Advantage (16IAX7) and I am unable to get the audio to work in archlinux. I also tried PopOS! and PCLinuxOS which was on 5.18. It only works in Windows

Enabling the CONFIG_SERIAL_MULTI_INSTANTIATE does not help in 6.0.3.
I also tried adding this quirk and compiling:
SND_PCI_QUIRK(0x17aa, 0x387, "Legion 7 16IAX7", ALC287_FIXUP_LEGION_15IMHG05_SPEAKERS),
I have not had the chance to go back and check in 5.18.

I also tried the 0.0.5 patch and that did not work either.

Here are the dmesg errors:

As referenced here:
https://bugzilla.kernel.org/show_bug.cgi?id=208555#c702

(Newer kernels had a patch that fortunately clarifies that it's a matter of missing _DSD properties)

Your laptop is missing the _DSD entries to setup this device. I suggest opening a support ticket. Hopefully with enough pressure, they'll add the entries. Especially since it doesn't require Lenovo to touch Linux or anything else other than to update their own BIOS images for the affected models.

Because the windows drivers from Lenovo have those values hardcoded into them.

Seems that Cirrus Logic generally expects these properties to be in the ACPI tables even for Windows. Sounds like missing properties is an issue in "older" laptop models. I don't think my model is very old, but could be that the work on it started earlier.

The properties are specific to a given laptop model and having the wrong values could physically damage your speakers. Before I knew this, I hard coded the values into a kernel patch and managed to get my own sound working. Fortunately, my speakers are fine.

I certainly don't know how, but perhaps the drivers could be reverse engineered to discover the values of the properties for a given model, and then you could override the DSDT like this to get your sound working:
https://wiki.debian.org/OverridingDSDT

IIRC, you could then use the Intel HDA early patching to set your laptop to use the quirk of another laptop that uses the cs35l41 quirk so you could get sound working without any changes at all to the kernel to get your sound working.

Hi, I might've missed this but - do we know for certain that the 7th gen Legion 7 (2022 model) uses the same amplifier chip as the 6th gen (2021 model)?

[cam (cam-linux-kernel-bugs)]

It does not, which is unfortunate, as the 6th gen model recently finally
got support.

The gen 7 uses the CSC3551 and the gen 7 is missing the properties in
the _DSD tables.

Do you already have the Gen 7? Try submitting a Lenovo support ticket
asking them to add the properties. I have a ticket they haven't follow
up on yet so I added a comment to the ticket I think less than an hour ago.

Does anyone know if both the intel and amd versions of legion gen 7 have the same problem with the DSD tables or just the amd version?

[cam (cam-linux-kernel-bugs)]

The Intel based Legion 7i Gen 7 definitely has this problem as I have one.

Any news from Lenovo support ?

[cam (cam-linux-kernel-bugs)]

None. Whenever I picked up their calls, it would hang up, so the ticket
would close. I'm going to try their support chat when I have time...
Whenever that will be.

No luck from my side, support stated that they don't support non Microsoft platforms for this model.

Same problem (so sound from internal speakers) here, with Legion Y740S.
Fixed it with adding to ALC285 quirks list to call alc285_fixup_ideapad_s740_coef.

sudo dmidecode | grep Family | grep Legion
        Family: Legion Y740S-15IMH

lspci | grep Audio

00:1f.3 0403: 8086:06c8 (prog-if 80)
        Subsystem: 17aa:3825

Patched against ubuntu tag: jammy-stable-v5.15.76, but should merge with vanilla 5.17+, too. Will attach patch for reference, hopefully this will be merged to vanilla upstream.

Hi Cameron,

I got my Legion Slim 7 Gen 7 AMD version yesterday and when I excitedly installed Fedora, I found the audio did not work. I would like to throw my weight behind this to get it fixed, but I don't know what to say to support exactly in my ticket. What do I need to ask them for?

I would really prefer not to have to send this laptop back. Is there anything else I can do to help?

I wish I knew. My understanding is that they have to add DSD entries in the next BIOS update. Maybe someone could elaborate further. When I put a ticket in they just sent me a generic sound troubleshooting guide for Windows. I am currently dualbooting hoping for an eventual solution (other than headphones or a bluetooth speaker).

[cam (cam-linux-kernel-bugs)]

Hello,

I'll follow up with you guys probably tomorrow (but possibly as soon as
later today). I've just been having an eventful holiday weekend.

As tomorrow is a normal weekday that I have off, I'll finally reach out
to Lenovo again tomorrow myself.

Doing a quick search, I don't think anyone has shared their Legion Slim
7 Gen 7 AMD alsa-info. Can someone do that? It's likely still the
CSC3551, but it would be good to confirm.

As for those ACPI messages... Looks like you have ACPI some stuff that
isn't supported under Linux yet. It's a fairly new laptop, so that's to
be expected. I don't really see that on my current laptop, but I do see
it with my current desktop which I've had for under a month (Asus
Crosshair x670 Extreme).

The CCP messages means Linux can't utilize the AMD Crypto Co-Processor
on your CPU. I've had this message for my current desktop as well as my
previous  (AMD 7950 and 5950 CPU's respectively). From my research, the
motherboard vendor (both Asus in my case) need to fix the BIOS. Maybe
it's a similar issue to what we're seeing with our laptops. While
unfortunately, it hasn't really impacted me.

I don't really have a plan of attack on this as I'm pretty busy generally. I haven't had time to follow up with Lenovo support yet. I'm just hoping if they get enough feedback, they'll do something. Otherwise, maybe we can try a petition?

But you might try explaining that all you need is for Lenovo to add the requisite info to the DSD table in a BIOS update. Linux doesn't need to be touched at all. Just a BIOS update. Here's a working example (that I got from https://bugzilla.kernel.org/show_bug.cgi?id=216194):

No, I just have a Gen 6 and it's still working fine on a patched 5.17 kernel.

I wish the kernel guys weren't so dead set against loadable DSDTs. There's still so many reasons why we need to be able to patch these ourselves and there's no good reason to have to rebuild an entire kernel just to add missing table entries.

https://wiki.archlinux.org/title/DSDT#Using_modified_code:

We should be able to override it. From here, using early patching should
allow you to specify using a quirk to support CSC3551.

 From there's a question of using safe values in your override.

Also, you won't have suspend/resume for the support for the amp chips
with the Gen 6 unless you're using a 6.1 kernel.

Found this thread after hours of trying to fix the audio on my Legion 7 Slim, Gen 7 as well most other things work OOTB, but audio isn't working.

[cam (cam-linux-kernel-bugs)]

I think none of the Gen 7 Legions have support.

Basically, all Lenovo needs to do is add some info to the ACPI _DSD
tables which will allow the cs35l41 drivers to know how to configure the
amp chips in our laptops. Lenovo so far has been unwilling to do this.

Maybe the AMD based Gen 7 does, but I don't remember on that one.

Hi Cameron, is that patch also good for the AMD version of the Slim 7 Gen 7?

[cam (cam-linux-kernel-bugs)]

No, only the 16IAX7 is covered.

You could a quirk for your laptop model... But I have to wonder how
different the speakers are for a slim model, which would concern me.

[aaronranderson (aaronranderson-linux-kernel-bugs)]

I wanted to report a similar issue on Lenovo Legion 7 Slim AMD. Onboard speakers do not seem to produce sound but in settings menu sound appears to be getting produced on the speakers. Headphones work fine. Thankfully I primarily use headphones but wanted to report the issue.

[pierrox (pierrox-linux-kernel-bugs)]

I own a Lenovo Legion Slim 7 Intel 16IAH7 with the same issue (no speaker sound but headphones ok).

Alsa-info for this particular machine can be found here: http://www.alsa-project.org/db/?f=9f1deb511b2604f1b52a7905889deb4463ca9211.

Would these alsa-info be enough for someone to create a patch for this model? If not, I'm ok to spend some time on the issue. I have no particular knowledge on how fixups are implemented but patching and compiling the kernel is not an issue. Probably I can take example on existing fixups to implement a new one. If so, some pointer on documentation or resource on where to start would be much appreciated.

[cam (cam-linux-kernel-bugs)]

For details around why this doesn't work as well as a use at your own
risk patch (which SO FAR has proven safe), look here:
https://bugzilla.kernel.org/show_bug.cgi?id=216194

The short short version is that Lenovo has zero interest in adding
entries in a BIOS update that would allow sound to work out of the box.

Thank you very much for the link! I missed this other discussion.
It doesn't work yet with my current 6.1.12 kernel (although the patch applies quite nicely) but I'll give it a try soon.

[pierrox (pierrox-linux-kernel-bugs)]

(In reply to Cameron Berkenpas from comment #737)

With Linux 6.2.1, I get the same error "Serial bus multi instantiate pseudo device driver CSC3551:00: error -ENOENT: Error requesting irq at index 0". I guess your patch is not reached at all then.

If I understand correctly, this is somewhat unrelated to this original bug, maybe I should look further around CS35L41 and/or serial multi-instantiate driver?

[cam (cam-linux-kernel-bugs)]

As the 6.1.x kernel worked, likely something else isn't quite right.

Are you sure you're running your patched kernel? Which patch did you apply?

I'm not too sure that this worked for the slim variant of the legion 7 gen 7, or at least jmaximusix, who uses a slim 7 too, doesn't seem to have it working neither (https://bugzilla.kernel.org/show_bug.cgi?id=216194#c49).
Also I get the very same error message regarding CSC3551 (where the serial multi-instanciate driver fails to get an irq in smi_i2c_probe).

I applied lenovo-7i-gen7-sound-6.2.0-rc3-0.0.4.patch and I have no doubt that the path is active in the currently running kernel. Unfortunately this is the only thing I know for sure, I'm sorry to be quite ignorant in most other areas regarding sound and amplifiers in Linux :-/

against 6.2.1

I put a disclaimer that this is a use-at-your-own-risk as the missing
settings were guessed for the full-sized Legion 7i, and it appears the
the Legion 7i has been working without issue since August or so without
any serious issues developing.

The previous patch includes 7i Slim support and it seems this has been
working for some people... If you've been using my patches for the 7i
Slim, I would like to hear if things are still working for you without
issue. With that feedback other 7i Slim users will be able to make an
informed decision on the use of these patches.

This updated patch adds support for the Slim 7 (AMD version). Same thing
stands. If there are serious issues such as perhaps loudness, distorted
sound, "amp short" messages in dmesg (when this happens the affected
speaker will no longer output sound), etc, I suggest to stop using the
patch to avoid the possibility of permanent damage (as well as following
up with your issues).

Since the 1-2 reports I saw that it seemed to work okay for the Slim 7i,
I suspect it will for the AMD based Slim 7 as well, but I can't make any
guarantees.

And finally... I did work on overriding the ACPI DSD table to get sound
working months back... While I did have some initial success, I was
running into "AMP short" issues. My patch was originally based on an
older version of the cs35l41 support and so it actually ends up
bypassing some of the code paths used in the current CS35l41 driver. If
I change the driver to go through that newer path, it has approximately
the same problems that using a DSD override does. So it seems my patch
works because it's "cheating" somehow due to historical reasons...

Probably the info I use in the DSD override is very slightly off from
what's needed, but if the issues could be ironed out... We'd have a
solution that didn't require patching the kernel. However, we'd still be
left with the problem of determining safe values and the values are
(more or less) going to be specific to your model of laptop.

This is why it's so frustrating that Lenovo won't add this info in a
BIOS update where as my understanding is that Asus has, in at least a
few cases, added these DSD entires in BIOS updates to get sound working
under Linux. As I no longer require my laptop to specifically have a
more professional Lenovo look, my next laptop will likely be Asus.

Like many of you, Linux is my daily driver (and has been since the late
90's in my case). But being able to boot to Windows to play games with
advanced optimus, some mild HDR support, etc... has been really great.

Anyway, looking forward to the feedback.

[pierrox (pierrox-linux-kernel-bugs)]

Yes, I confirm that the patch includes the slim 7 in the list of fixups, with the right "16IAH7" model number and right numeric id: 0x17aa:0x3803 (same as my alsa-info), so I thought there was some success for this computer. But rewinding the discussion to the top in this thread and the other one (https://bugzilla.kernel.org/show_bug.cgi?id=216194) doesn't show any evidence of success for the "slim" variant. Or maybe I missed it?
I noticed that the clear text name for the entry in the patch is named "Legion 7" not "Legion S7". Maybe there's some mismatch here? I mean: could the slim references have been used in place of another model, maybe another 7 variant? Lenovo's naming scheme is confusing: there's the 7, the 7i, the 7 Pro and the S7 which is either named S7 (without "i" no matter Intel or AMD) or Slim 7 (only AMD) or Slim 7i (only Intel).

I understand the issue with DSD and why it's frustrating. This isn't by far the first frustration I get with this kind of issue... But fortunately these little issues are more than balanced by the benefits of running Linux :-)

Using 6.2.1 on my slim 7i (16IAH7), the cs35l41 driver fails to load. If my understanding is correct, this will prevent code in the patch to be executed, even if some code paths in cs35l41 are bypassed by the patch, right? Please correct me if I'm wrong, as really I'm a newbie in this area.

I'm 100% sure that the patch is applied though, but I don't see the related printk in the kernel log (in particular there is no "CSC3551: probing"). What I am trying to understand is whether this is because of the cs35l41 error, and in which case I should look into this issue first, or whether this is due to another problem.

While unloading and reloading cs35l41 modules (snd_hda_scodec_cs35l41_i2c snd_hda_scodec_cs35l41_spi snd_hda_scodec_cs35l41 snd_soc_cs35l41_lib snd_hda_cs_dsp_ctls cs_dsp), there's no indication of the driver being initialized again in kernel logs, so my guess is that this is triggered by another sound module. Would you have any hint on a what should be done to unload/reload the sound subsystem and avoid reboot between each code modification/build?

Thank you so far for the help and the patches. Even if I cannot ever hear sound from the speakers (and I can perfectly live with this), your work is really appreciated!

[cam (cam-linux-kernel-bugs)]

The name doesn't matter, just the numeric ID. If I had a patch worth
submitting, I would fix the names but otherwise they don't matter.

Please share the following outputs with me:
uname -a

And mostly I need this:
dmesg | egrep -i '(csc3551|cs35l41|reset_gpio|short|adev|speaker)'

Hello Cameron.
Do you think this patch for Slim 7 AMD versions be viable for Yoga Slim 7 Carbon 14ACN6 as well?

Yes exactly, I have the same laptop and the same issue. If you find any solution, be sure to let me know, and so will I! :D
I think I might be able to clear up some confusion around a patch existing or not. Cameron Berkenpas did try to add support for the Slim 7i using some logs I provided, but that didn't turn out fixing the csc3551 error. So thats why, I think, in his patch, the Slim 7i model (16IAH7) is listed, but it's not working, at least I am unaware of any success anybody had with it.

I have more or less given up on this for now, because at least with my (nonexistent) knowledge of this stuff, I don't see anything in my power I can do. But if anybody has ideas what to try or where to look, I'll happily try it out.

[cam (cam-linux-kernel-bugs)]

See https://bugzilla.kernel.org/show_bug.cgi?id=216194 for a new patch. Currently the latest is lenovo-7i-gen7-sound-6.2.0-rc3-0.0.5b-002.patch

This latest patch theoretically has support for Blake Lee's machine.

A new revision of the 16IAX7.

Pierre Hébert,

I missed that you were getting this error previous: "Serial bus multi instantiate pseudo device driver CSC3551:00: error -ENOENT: Error requesting irq at index 0"

That is indeed occurring before any of my code. Some hopefully good news is that this is a Cirrus Logic issue that they might fix if you can report it to them. Once fixed, you'd probably still need a patch such as mine to get you over the finish line.

PLEASE READ MY COMMENT HERE AS THIS PATCH IS USE AT-YOUR-OWN-RISK:
https://bugzilla.kernel.org/show_bug.cgi?id=216194#c66

From here on out, I will direct people to bug https://bugzilla.kernel.org/show_bug.cgi?id=216194 as there's far too many posts in this thread and it's made things difficult to keep track of.

Hey Cameron, I did apply the patch against kernel 6.2.2 for the 14ACN6.
There was sound from the 2 tweeters as before the patch was applied but still I don't know if the 2 woofers are actually active?
Not sure what the best way to find out if woofers are working.
Is there anything I can do with speaker-test?
But I'll try to compare before and after patch.

I was going to try to sniff the verbs for this laptop but the problem is that the audio controllers are on the same IOMMU groups as radeon gpu, pci, usb and psp.
So I cannot not passthrough the audio devices without ACL override.

Looking more closely at your alsa-info... You have:
/sys/bus/acpi/devices/CLSA0102:00/status

I didn't even know the CLSA0102 existed! Just the CLSA0100 and the
CLSA0101. I don't think that's supported at all at this point. You might
try reaching out to Cirrus Logic. I think that's your best bet. There's
certainly nothing I can do. Sounds like the CLSA0102 's are strictly for
your the woofers?

CLSA0102 is almost certainly going to fall under cs35l41 and like the
CLSA010/1, it would likely need a custom code path.

Really wish Lenovo would play more nice with us. Yes, they have Linux
specific offerings, but like most of you, I'm not interested in those.
And in case anyone from Lenovo is listening... I'm not personally
interested in getting ANY Lenovo support for Linux. I just want my
hardware to work.

Hey again, sorry I just now noticed this: on my 2021 Legion 7 16ACHg6, the sound from the left speaker is much quieter than from the right speaker. Is there anything I can tweak to adjust this?

One last note - playing a particular video clip (Star Trek Strange New Worlds S01E10), the opening splash sequence, the maximum loudness in Linux was only 65dB, and 78dB in Windows. Volume control set to 100% in both cases, identical video file.

I have the same laptop model (Legion Slim 7 Gen 7 16ARHA7) and I have the same issue and audio info dump, posting a reply to let the world know I have the same issue.

It's a really great laptop that works amazing with the newer kernels, except for this one thing! Sound even works when connected to 3.5mm or a USB sound device. It's just the built-in speakers.

My Yoga 9 14IAP7 was working well since post #733 above. However I recently booted from kernel kernel-6.2.8-200.fc37.x86_64 to 6.2.14-200.fc37.x86_64 and I get no sound.

Hi, I have a thinkbook 16p Gen4 using archlinux with 6.3.1 kernel. The sound only works on 2 out of the 4 speakers (No bass, low volume). Accoding to https://psref.lenovo.com/Product/ThinkBook/ThinkBook_16p_G4_IRH, the audio chip is ACL3306-CG. I wonder if this is the same chip as the ACL3306, or it will require another driver? Also, I wonder if my problem is caused by the audio chip or the smart amplifier?

I have the same issue on a 83BU Yoga Pro 9 14IRP8. I can see some lines that look suspicious in the logs:

skl_hda_dsp_generic skl_hda_dsp_generic: ASoC: Parent card not yet available, widget card binding deferred

I'm running Fedora 38 with 6.2.15-300.fc38.x86_64.

[Alexis CUGLIETTA (acuglietta)]

I have the same problem with a ThinkBook 13x Gen 2 with Ubuntu 23.04. The sound works properly when connecting external speakers or headset, but I couldn't get the internal speakers to work :( This laptop also has an ALC287/3306 chip with a CS35L41/CSC3551 amplifier. This seems very similar what is mentioned here:

https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff?permalink_comment_id=4526397

journalctl displays the following message: "Error: ACPI _DSD Properties are missing for HID CSC3551".

I tried it with the base kernel (6.2.0) as well as the latest one (6.3.3). The issue occurs regarless of the BIOS version (factory version: HXCN49WW and 20230517 version: HXCN52WW).

I used the ACPICA tools to extract the ACPI tables and noticed the entries relative to the CSC3551 did not contain the required "cirrus" and "dev-index" parameters.

This is quite disapointing and I will juste return the laptop to Lenovo.

[alexis.cuglietta (alexis.cuglietta-linux-kernel-bugs)]

I do have exactly the same issue on a ThinkBook 13x Gen 2 running Ubuntu 23.04 (kernels 6.2.0 and 6.3.3): no sound from the internal speakers, although sound works when using the external 3.5mm jack. The laptop has the same chips: ALC287/3306 codec and CS35L41/CSC3551 amplifier.

journalctl displays the following message:
"Error: ACPI _DSD Properties are missing for HID CSC3551"

I have extracted the DST tables using ACPICA and did not see any reference to the 2 parameters required by the CS35L41 driver: "cirrus" and "dev-index".

My conclusion is there is probably some work required from the Lenovo BIOS team :(

Alas, you are correct. The good news is that this is being worked on for
the Legion... But it seems to be for the latest model of the Legion
(which does haven't Cirrus Logic, it has TI smart amps IIRC). I have the
2nd to latest (which I think came out less than a year ago).

Hopefully from there they can work on my model... And perhaps Lenovo can
begin to branch out from there.

It's really too early to guess where things will go, but I'm hopeful.

I just found https://superuser.com/questions/1719920/no-sound-from-internal-speakers-on-laptop-but-headphone-jack-and-hdmi-works with the link https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff

It sounds very much like this problem right here. Can we build a workaround for our machines? Extracting the respective data from Windows and injecting it into our Linux istallations?

[cam (cam-linux-kernel-bugs)]

I haven't been able to get this working properly. I was able to get
sound with this approach a few months ago, but I was getting "AMP short"
errors, which I'm sure can't be good.

I have the Legion S7 16ARHA7 w/ Cirrus amp. I've been patching the kernel using lenovo-7i-gen7-sound-6.2.0-rc3-0.0.5b-002.patch with working sound. However, I'm not able to hibernate my laptop successfully. It will hang after saving to disk but it won't shut off on it's own - just stays on with a black screen with the fan going. Then it drains the battery until it dies. If I turn it on again, it will successfully resume from hibernation. I'm not sure what is causing it. It works find if nothing is open (just gnome-shell), but as soon as I open firefox or chrome the problem recurs if it goes to hibernate. Did anyone else have the same issue?

[cam (cam-linux-kernel-bugs)]

This is probably the same as an Nvidia driver issue that I've had... Or
similar... I had the same issue with the Gen 6, and gave up hibernating
completely with the gen7/8.

I could hibernate & resume 1-2 times, and then when resuming... the
laptop would hang, eventually my desktop session would crash and I'd get
the login screen. When not using the Nvidia GPU at all, it worked
consistently.

This is the error I'd see in dmesg:
[   14.045062] nvidia 0000:01:00.0: PM: failed to quiesce async: error -

Seems you can't even shutdown... I don't remember if I encountered that
problem.

Try uninstalling the Nvidia drivers or blacklisting the nvidia module
and see if it still occurs.

Thank you for the info. I have AMD graphics, but might still be the same issue.

When I look at the dmesg I only see mt7921e errors. I tried unloading the wifi driver but it didn't make a difference.

So, this patch can solve the sound problem, right? Enlighten me pls, I would sacrifice everything to hear my laptop.

[cam (cam-linux-kernel-bugs)]

Depends on which laptop you have. It will work if you have the Legion 7i Gen 7, but not for the Gen 8 (but there is work to get the Gen 8 working that will be mainlined).

Share a link to your alsa-info.

Here is the URL:

[cam (cam-linux-kernel-bugs)]

Then sounds like your laptop is supported by my patch:
https://bugzilla.kernel.org/show_bug.cgi?id=216194

This patch will never make it into the kernel. But if you are able to apply the patch and build your own kernel... This will get you sound.

Amps are working on Yoga Pro 9i 2023

I got my amps working. If your device has a TIAS2781 component inside (http://alsa-project.org/db/?f=45447739750ff897cdc20fd0e98d4f2055beebdf <- note line 71), you can try the following:

Install i2ctools first and then run ./2pa-byps.sh with the i2c-bus number where your TIAS2781 is connected. E.g:

sudo ./2pa-byps.sh 0

In my case this enabled my subwoofers and the sound was working properly.

This change will be included in the kernel in the next couple of weeks / months so no workaround will be necessary anymore.

Looking at the patch this looks like a microphone quirk patch. It does not look like it patches the audio output side of things.

Do you know of a patch or patch submission that is for audio out on the Legion 7 Slim AMD edition (16ARHA7)?

I was wondering how do I apply any patches? I'm on a legion 7i gen 7 and was wondering how to add patches because I wanted to try out if any patch works for my system, thank you.

What about Lenovo Legion Slim 7 Gen 8 2023 ? does sound works ? i've seen that work will be mainlined as said in the comment 774 but when ?

[andrewdubya (andrewdubya-linux-kernel-bugs)]

Is there some way I can help to get Realtek/tas working for the Lenovo Slim Pro 9i (named Yoga Slim 9i outside of the US)?

On my Manjaro install, the top speakers work (although I don't think they're amplified?) and the bottom subwoofers are off.

I've managed to get qemu working for sniffing following this guide:
https://github.com/ryanprescott/realtek-verb-tools/wiki/How-to-sniff-verbs-from-a-Windows-sound-driver

At one point, Win10 in qemu had sound working similar to Linux (only top-firing, maybe unamplified), and I saw event logs, but I don't remember the driver. I might need to do a clean install at this point.

When I try to install the driver in qemu in win10 or win11, I get a bluescreen. Windows is using Realtek Semi Corp ver 6.0.9553.1.

[cam (cam-linux-kernel-bugs)]

Andrew, the verb approach doesn't work here as smart amps are being used.

The tas2781 smart amp is generally supported as of kernel 6.6... but now it's a question of if firmware for your laptop is available.

Without your alsa-info, I can't tell if your laptop is supported...

But you can just try the firmware for yourself from here:
https://neo-zeon.de/~hiryu/tas/firmware-6.6.tar.bz2

Just copy the files into /lib/firmware/ and reboot. Hopefully you have sound.

A number of Lenovo laptops with tas2781 are supported, but I don't think the list is anywhere near comprehensive so we'll see..?

Good luck!

I'm not sure if these firmware files are yet in the pipeline to be commonly redistributed at this time... I'll see if there's something I can do to get that process started.

Thanks Cameron! Adding those files to /lib/firmware didn't work (I copied
the files directly), so I'm probably out of luck for now. I've attached my

It seems the sound no longer works for the legion 7 16achg6 on kernel 6.6. It's been working great for the last year on all kernels, but 6.6 just doesn't work.

I'm not sure if anyone else is having similar issues? Manjaro Linux here.

I had no luck with sound on Ubuntu's 6.2 either. I dropped back to 5.19 to get sound working again.

The C940 also has alc298 and tas2770.
Please try this:
sudo nano /etc/modprobe.d/alsa-base.conf

The file didn't exist and therefore was empty. I added the line and saved the file. There was no change after rebooting. I still get sound, but the same as before, only high-pitched with no base. Does there need to be something additional in the file or some other configuration? Is there some configuration to enable the speakers that give the base?

Hey it looks like Lenovo has released a new BIOS version for the Legion S7 16ARHA7 Slim model (the one I have that still has no sound). I'm curious if anyone has updated to this BIOS yet and if that's resolved any issues or if this would allow further development on the audio issue.

i got the sound working on my 16APH8 (Slim 7 AMD Gen 8 2023). I mainly followed this guide https://gist.github.com/masselstine/8fe9634b4c31cef07b8dfab089e4eb38 .
Just check if the Cirrus chip is connected in I2C. You can know that by putting kernel in log level 7 and seeing logs in dmesg.

Just make sure to shutdown and unplug power, wait about 10s and boot up again to test the sound everytime

Weirdly simple, but wow, this cannot be it. Hallelujah!!!! After a few days reading and testing many things, I finally have audio! Apparently, it was missing (some?) library required for pipewire. I have a Legion 7i Pro running popOS on kernel 6.6.6-76060606-generic. Try running this command:

sudo apt install libpipewire*

Two library files were installed:

libpipewire-0.3-dev:amd64 (1.0.0~1701092078~22.04~594e8f5)

libspa-0.2-dev:amd64 (1.0.0~1701092078~22.04~594e8f5, automatic)

Then, I rebooted, tested audio, and voila!

Hey! Looks like this acp6x-mach/yc_acp_quirk_table workaround would also be needed for Yoga Slim 7 Pro 14ARH7 (LENOVO/82UU). I have one, and the microphone does not works.

ALSA info:
https://alsa-project.org/db/?f=77e94edfeb14c5e3bf3ffb9524fb5d8390e1b722

From the kernel logs looks like snd_pci_acp6x detects and enables a device:
```
[ 7.120140] snd_pci_acp6x 0000:32:00.5: enabling device (0000 -> 0002)
```
but then there is nothing acp_yc_mach related in the logs.

I would appreciate if you could make a patch. Thanks!

I have been lurking on this thread for a while. This thread has been up and still active since 2020, I don't even know where / which suggestions I need to start following.

I have 16ACHg6 too, (Alsa says that) it's running Realtek ALC287. I have a fresh install of Ubuntu 22.04 with kernel 6.5.0-14-generic, I have updated my BIOS and internal speakers hasn't been working at all since the first day. External speakers (headphone, Bluetooth speakers) work just fine though. Still no luck with 16ACHg6 then ?

[cam (cam-linux-kernel-bugs)]

I believe support for the 16ACHg6 was added quite a ways back.

Yes, it was added in 5.18. It is broken in 6.x. That's why I still only run 5.19 on my machine. The comment below says it actually stopped working in 6.6. I can't confirm that it worked in any earlier 6.x kernels, I had no luck with it.

Canonical occasionally breaks sound compatibility between kernel release (but I yet to figure out why). However, the XanMod kernel quite rarely breaks Lenovo sound compatibility, thus I suggest you give that kernel a whirl: https://xanmod.org/ (It's quite easy to install and remove if needed).

Yes, I tried a few patches including the last one : linux-legion-sound-0.0.13. I can confirm it is not working on my 16ACHg6 with kernel 6.5.0-14.
Thank you so much by the way for all of your help with so many patches !

Hey, I have a Lenovo Yoga 7 16IAP7 with Fedora Workstation 39 installed.

Kernel Verion: Linux 6.6.11-200.fc39.x86_64
alsa-lib version: alsa-lib-1.2.10-3.fc39.x86_64

I installed alsa-tools and went into hdajackretask to see what is going on. Then I noticed that my System is telling me that I have an ALC287 installed but actually it is a ALC3306. Sound is horrible and several fixes with ALC 287 for Legion Models did nit work. In the Settings I can see as well, that only 2 of the 4 integrated speakers are getting noticed.

I have had this Problem for a while now.

Comment #806 said that this should have worked till 6.6 and then it broke again. I had a fresh install of Fedora 38 back then with the Kernel 6.4.6-200.fc38.x86_64. It did not work form me with this Kernel either.

Are there any news or is there hope of fixes?

[dlinuigh (dlinuigh-linux-kernel-bugs)]

Don't mention it, I've already given up. At first, I thought maybe some patches would "heal" this problem, then I believed the new kernel would work, now I solved this problem by ignoring it and wearing my earphone.

I use a Lenovo Slim 7 Carbon with a ALC287 as well.

We have an issue page open for this device/issue as well, and I think we nailed it down to the pin configurations.

I have a "Lenovo Legion Slim 7i 16", and several days ago, out of nowhere, the speaker started working. I have no idea how -- I did not change anything manually. I suspect it's a new kernel version that did it.

Anyway, good news!

Amazing

I would like to reproduce this. You can find out your current kernel version with the command "uname -r". The installed sound packages/libs would also be interesting. What I know of would be to look at the alsa version.
Someone else surely has more information on what to specificly look for and how.

Yep! I'll post this kind of info before the end of today, check back in a few hours.

I can tell you now that the speakers first started working when using pulseaudio as my sound server, but soon after (in order to get bluetooth working nicer) I switched to pipewire.

Okay, so my kernel version is 6.7.2-arch1-1

These are some (maybe all) of the audio related packages I have installed:
kpipewire 5.27.10-1
libpipewire 1:1.0.1-2
pipewire 1:1.0.1-2
pipewire-alsa 1:1.0.1-2
pipewire-audio 1:1.0.1-2
pipewire-jack 1:1.0.1-2
pipewire-pulse 1:1.0.1-2
libpulse 17.0-3
pipewire-pulse 1:1.0.1-2
projectm-pulseaudio 3.1.12-4

But I can verify that my speaker did also work _before_ I switched from Pulseaudio to Pipewire, seems both should work.

The result of running alsa-info is here: http://alsa-project.org/db/?f=07a1fdaf34a424adc27dbb6be3f417995df6994f

Good luck!

atm i did not get it to work. i habe all the same packages or newer installed. hoping newer verions did not brick it again this means it would have to be the kernel. fedora 39 stabe only gets access to 6.6.13. tests for 6.7 are beeing done.

i even tired to switch to pulse and back. no changes.

will provide mor info when new kernel is here. maybe someone can provide info on weather fedora and arch kernel are vastly different as yours specificly says arch in the version. mine does not

I am running an 14IRP8 (Yoga Pro/Slim 9i), specifically this model (https://psref.lenovo.com/Detail/Yoga/Yoga_Pro_9_14IRP8?M=83BU0024AU).

I have the laptop running Ubuntu 23.10 and I run mainline kernels from Ubuntu. I have tried almost every recent kernel build up until 6.8-rc5 today (I had read that 6.8 was supposed to fix this issue). Audio is still running only the tweaters, zero bass.

I've tried many things, notably the snd.conf (options snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin) to no avail. Also tried noble's firmware-sof-signed package, manually tweaking the amixer configuration.

Not sure what the cause of this is, but there is no specific mention of "14IRP8" in any of the kernel code, so I guess there is still no specific support for your issue, unfortunately.

Possibly the fix would be as simple as the commit which fixed it for the 16IRH8 (just several lines of code https://github.com/torvalds/linux/commit/99af5b11c57d33c32d761797f6308b40936c22ed), but I don't know enough about any of this to say for sure.

[soyer (soyer-linux-kernel-bugs)]

Based on alsa-info, its subsystem ID is: 0x17aa38be

It's here in the patch_realtek.c:

SND_PCI_QUIRK(0x17aa, 0x38be, "Yoga S980-14.5 proX YC Dual", ALC287_FIXUP_TAS2781_I2C),

snd_hda_scodec_tas2781_i2c loaded.

Could you run this as well?

dmesg|grep 2781

[thornley.david (thornley.david-linux-kernel-bugs)]

I noticed that patch is present in the kernel I am running...

"dmesg | grep 2781" yields nothing.

"lsmod" indicates snd_hda_scodec_tas2781_i2c is loaded.

I'm quite green with the audio subsystem in linux, so pretty overwhelmed and suprised how complicated it is :) I'm not 100% sure, but it sounds like there is firmware and associated tuning values present in the EFI system that are also required.

One other thing I noticed, running "i2cdetect -r 3" doesn't report any probed addresses. -r 1 has one at 0x14, -r 2 has at 0x2c, less that I think expected based on other similar posts.

Do you have full volume sound? I have a similar model (https://psref.lenovo.com/Detail/Lenovo/Lenovo_Slim_Pro_9_14IRP8?M=83BV0002US) and had to do a few things to make the amplifier work in the first place, but I still don't have any bass.

To get sound on linux 6.7 I had to update the firmware files and use `options snd-sof-intel-hda-common hda_model=17aa:38be`, which had a different effect to alc287-yoga9-bass-spk-pin (not sure why). I described with more details at https://github.com/PJungkamp/yoga9-linux/issues/11#issuecomment-1899400594

I didn't try a lot on 6.8 but my current config doesn't fix the bass there too.

[thornley.david (thornley.david-linux-kernel-bugs)]

I do now :) You're right the hda_model=17aa:38be definitely forces the tas driver to load properly (it is in dmesg) and the firmware link seemed to fix a NULL error when I first tried it.

[ 5.770034] snd_hda_codec_realtek ehdaudio0D0: bound i2c-TIAS2781:00 (ops tas2781_hda_comp_ops [snd_hda_scodec_tas2781_i2c])

I tried both 6.8.0-rc5 and then fell back to 6.7.5 because in both of these the volume control didn't work at all (seems to be at full volume), even in "alsamixer -c 1". Note that originally, the sound was low/quiet but volume control did work.

[soyer (soyer-linux-kernel-bugs)]

Could someone please test if changing this fixup in the sound/pci/hda/patch_realtek.c fixes the volume control?

Just tried it and it indeed works, nice! Do you know if this will be merged soon (hopefully before 6.8 release)?

It still requires `options snd-sof-intel-hda-common hda_model=17aa:38be` (doing nothing or using `hda_model=alc287-yoga9-bass-spk-pin` doesn't work). But now I can control the volume using the default "Play HiFi quality Music" without janky work around.

Great to hear!
I can create a patch, and it can be included in 6.6 and 6.7.

Can you test whether the headset jack works also?

And could you run alsa-info.sh? I think your model needs to be added to the patch_realtek.c to make it work without the module parameters.

I can confirm that headset jack works perfectly with this patch. With 6.7 it didn't even detect the headset plugged (didn't test it on 6.8 without the patch).

I don't know how but the bass on Windows is still much better and I always hear a strong beep from both speakers when I get past the sddm lock screen when I turn on the laptop.

[cam (cam-linux-kernel-bugs)]

The strong beep suggests you might have the older firmware.

If you have the old firmware, you might also notice your sound for your
left and right speakers are swapped.

The speakers are not swapped but how can I check the current version and update these firmwares?

I moved the firmwares from https://neo-zeon.de/~hiryu/tas/firmware-6.6.tar.bz2 to /usr/lib/firmware, so not sure if this affected something.

[cam (cam-linux-kernel-bugs)]

Then that's the latest firmware as far as I know (that's my server lol).

Not sure why you're getting the beep then.

The latest firmware is probably in the linux-firmware package.
Do you still hear a difference when you disable Dolby in Windows?
Do you hear the beep after hibernation also?

Oh, didn't know the server was yours, thank you lol. Unfortunately, the firmwares are not up to date compared to kernel-firmwares. Specifically the files TAS2XXX3881.bin, TAS2XXX38CB.bin, TAS2XXX38CD.bin, TIAS2781RCA2.bin.

Updating the firmwares fixed the loud beep (which also sounds like something really broken) and my bass is much better than before. As a very subject comparison, the working bass at low volume makes my table shake a little, the old firmware sounds flat and doesn't move anything even at the highest volume. Windows is still a little better but probably because of the tuning than anything else.

I tested the new firmware without the module parameter just in case it also fixes that, but it still doesn't work without it.

There is an ID collision.

Your audio controller's PCI SSID (17aa:3802) is the same as the "Lenovo Yoga DuetITL 2021" Codec SSID. The snd_hda_pick_fixup() function searches the PCI SSID before the Codec SSID in the same table. So it picks the ALC287_FIXUP_YOGA7_14ITL_SPEAKERS fixup not the ALC287_FIXUP_TAS2781_I2C.

!!PCI Soundcards installed in the system
!!--------------------------------------

00:1f.3 Multimedia audio controller [0401]: Intel Corporation Device [8086:51cf] (rev 01)
 Subsystem: Lenovo Device [17aa:3802]

I think a common fixup can be figured out, or a better solution from someone who knows this subsystem well.

Hm I see, not sure if this is the right place to talk about the code, but is there a reason for the fixup table to be the same for PCI and Codec SSIDs? (I know it's not like it could be separated at this point). Also, is there a reason to match by PCI before Codec? A few ideas I thought:

1. Just check if the PCI and Codec SSID match the exact SSIDs of this device (not elegant)
2. For every lookup, check with both

Depending on how hard this problem is I may want to help with the code if possible.

I don't know the reasons, but this code has been working in this way for 10+ years, so this type of collision can not be common.

I also tried the two changes above to 6.7.6, it took a bit for me to work out how to compile a custom kernel in ubuntu (easy once you know). Mine is a slightly different 14IRP8 device Yoga Pro rather than Slim Pro (same underlying hardware).

Alsa-info -> https://alsa-project.org/db/?f=3adac42b53db18376ea17cd5ab008c247a4039a5

Applied the latest firmware to /lib/firmware from https://gitlab.com/kernel-firmware/linux-firmware.git (branch main).

Confirmed no options are now required, overall sound is considerably better, volume works, headphones also work.

Subjectively audio doesn't seem quite as good as in Windows, where the bass seems to get dynamically adjusted depending on the volume (maybe some fancy DSP effects, not sure - I am only guessing). Either way, it is now light-years better than what it was before the changes.

Many thanks Gergo K. :)

Confirm. Lenovo Legion 7 slim (R9000X) 16ARHA7. Speakers start working since upgrading to 6.8.5 kernel.

But internal microphone doesn't. But maybe it's some local problem, I have never checked it before.

Does internal microphone work in your OS ?

[dreamsyntax (dreamsyntax-linux-kernel-bugs)]

Hi, just confirming that on:
Lenovo Legion Pro 7i (Gen 8 / 2023) the no sound issue has regressed again on 6.8.5.

Last working version without any issues is 6.7.9 - which is odd considering the original post lists this as not a regression?

alsamixer shows ALC287 under system info.

6.8.2-6.8.4 have no audio for me.
6.8.5 has audio on reboot, but after a seemingly random amount of time the audio will no longer function until next reboot.

6.7.9 works at all times for me.

I also have the Legion Pro 7i Gen 8 16IRX8H, sound worked through all those kernel versions for me... But I do have another problem I wonder if it's related... Occasionally, my sound will just stop working. I can't get it working until I reboot... This tends to happen at a rate of less than once per day.

Last time it happened was yesterday. This time I decided to enable hibernate to see if resume from that would restore my sound (resuming from sleep doesn't work).

Anyway, the issue didn't happen to me for about a month... and then happened to me twice recently. Maybe it started around 6.8.4 or 6.8.5? When it happened yesterday, I was on 6.8.6.

The problem is so intermittent it's hard to pin it down to it starting with a specific kernel version...

But it makes me think maybe our problems are symptoms of the same issue.

How are you getting recent kernels? Are you self compiling? Are you using the Ubuntu mainline repo? Something else and/or some other distro entirely?

I'm compiling my own.

When this happens, audacious gives me some ALSA input/output error. I suspect some hook to tell the amps to wake up and play audio through the speakers hangs, but that's all I've got so far.

But sound issues related to TI's smart amps are definitely unrelated to this bug we're posting in. Someone should start a new bug for these issues if we hope to get more support.

> ...it makes me think maybe our problems are symptoms of the same issue

I agree. I am using endeavour os, but I've also verified my scenario on
nobara (fedora based).

I found I can somewhat reliably get the audio to fail on 6.8.5 by leaving
the system muted for a few minutes. Additionally something I noticed on
6.8.0 is running a video in a Firefox based browser (I used Librewolf),
pausing and unpausing could lead to the sound being permanently disabled
for the whole system until reboot.

I am not self compiling, just using the arch linux and linux-headers
packages. If this bug tracker is for debian/ubu based distros only, my bad.
The issue is reproducible regardless.
I can only confirm that I experience no issue on 6.7.9 on fedora based
distros and arch. I think I had no luck using 6.7.9 on linux mint (using
mainline kernel), but I assume it is because of an outdated linux-firmware
package.

If it isn't a pain for you to test, could you try 6.7.9 and see if you
experience no issues as well?

[cam (cam-linux-kernel-bugs)]

I can try 6.7.9 and 6.7.12.

What you described vaguely sounds like the stuff I'm doing when it
breaks on me so I'll try that too!

I might have some time to do this tomorrow night.

The firmware files have not changed.

I think it's possible that this commit is the culprit:
https://github.com/torvalds/linux/commit/bec7760a6c5fa59593dac264fa0c628e46815986

Sorry about that, it works fine with tas2563, but I couldn't test it with tas2781.
Something related to power management can cause this also.

Please try the following and report if it fixes the issue:

amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1

It is possible that the -c 1 and the numid parameters are not exactly these, they can be obtained from `amixer -c 1 contents` or `amixer -c 0 contents`.

Thanks,
Gergo

[cam (cam-linux-kernel-bugs)]

I had some time this morning to try and repeat the issue.. I couldn't do it. So until I can find a way to repeat it, it's not worth testing other kernel releases.

I will try Gergo's command once it happens again and report back.

[soyer (soyer-linux-kernel-bugs)]

What else came to mind, the driver currently writes the calibration data to one of the wrong registers of tas2781, which can also cause problems. If anyone wants to know what fixes the problem, please try this patch as well:

Pretty good find/catch! I checked the source of my current kernel

We'll see how this goes...

I can reproduce in < 5 mins on average.

I played a video and paused / resumed after a while, until the issue kicked in.
Ran: `amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1`
No effect, sound still broken. The output looked ok.
Checked both `amixer -c 1 contents` or `amixer -c 0 contents`. - there
are a lot of entries, what exactly am I looking for?

Here's the interesting part though:
In that same session, I made the laptop close lid action + sleep
On wake, audio was working again.

Hi, I had this issue for some time but thought it was because of bad setup in my part. This command seems to fix the issue without having to rewake the laptop. I'm testing your patch and will report back soon.

[soyer (soyer-linux-kernel-bugs)]

Hi,

> there are a lot of entries, what exactly am I looking for?

Find the card with 'Speaker Force Firmware Load' control, then change the -c and numid parameters accordingly.

> What is the expected result of the above?

It reloads the program of the amplifiers before powering up the amplifiers. (amplifiers (software) shutdown occurs after 3 idle seconds)
If you set it to 0, the program will only be reloaded after module init and after wakeup/rewake.

you can check the value of the control with:
amixer -c 1 cget numid=3,name='Speaker Force Firmware Load'

Before bec7760a6c5fa59593dac264fa0c628e46815986 ("ALSA: hda/tas2781: do not reset cur_* values in runtime_suspend"), the driver reloaded the program and configuration every time, and this control wasn't effective.
Reloading the program and config takes 0.3 second or more, that's why I wanted to remove that behavior. It's annoying to wait every time you start anything.

I can only guess what could be wrong with tas2781 setups. Probably the amps will go into failure state or reset state after a while.

It would help if someone dumps the registers as root, when the amplifiers are not working:

rmmod snd_hda_scodec_tas2781_i2c
i2cset -y 3 0x70 0x00 0x00
i2cset -y 3 0x70 0x7f 0x00
i2cdump -y 3 0x70
modprobe snd_hda_scodec_tas2781_i2c

first line unloads the module
second line changes the page to 0x00
third line changes the book to 0x00
fourth line dumps the page
fifth line loads the module

The bus number (3) may be different.
The address of the second amplifier is 0x72.

Here is the data sheet, if anyone wants to dig :)
https://www.ti.com/lit/ds/symlink/tas2781.pdf

[dreamsyntax (dreamsyntax-linux-kernel-bugs)]

A few things since I last posted:

After having done the below command...
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1`
Every subsequent reboot the audio never broke. I had multiple 2+ hour
sessions with no issue.
I never re-ran the above command.
Adjusting the volume would have a noticeable 'delay' (around 0.5
seconds to 3 seconds) before the audio mixer related GUI would
respond.

As a test I did a fresh install of endeavour-os (on kernel 6.8.7) and
sure enough, the issue is back and I can break the audio in less than
5 minutes of use.

> It would help if someone dumps the registers as root, when the amplifiers are

works, so if I'm doing something wrong please let me know.

For testing purposes, if I want to enable/disable your workaround
solution, would changing the 1 at the end to 0 be sufficient?
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 1` ->
`amixer -c 1 cset numid=3,name='Speaker Force Firmware Load' 0`

The alsactl restores all audo controls after boot, including this one.

Yes, setting it to 0 disables always reloading.

Unfortunately, my sound finally did fail again... But the symptoms seem different. Audacious just hangs for a while before ultimately giving up (and it stops hanging and stops trying to play).

But this is a new type of failure so perhaps this patch did make a bit of a difference?
https://bugzilla.kernel.org/show_bug.cgi?id=208555#c863

But this happened immediately after resuming from suspend. My laptop went to sleep with mute enabled, I started playing sound after resuming, noticed I was muted, and resumed... And sound was no longer working.

Could bec7760a6c5fa59593dac264fa0c628e46815986 be the issue?

This did not fixed my count:
amixer -c 0 cset numid=3,name='Speaker Force Firmware Load' 1

(-c 1 is incorrect for my laptop.)

Forgot to get the dmesg even though I did look at the dmesg output (*facepalm*). There are no messages related to this in dmesg when this occurs. But next time it happens, I'll get this to you to be thorough and Just In Case.

Sorry if this is a bit long, but trying to include info to help debug the issue.

Well, it has finally happened again... It seems like the script hasn't really helped... But I'll have to try it again next time this happens to determine what, if any, role it had. So far it looks like it hasn't helped.

I was able to get my sound working by running this: "killall pipewire-pulse" and quitting/killing audacious (audacious usually but not always hangs when this starts happening), and quitting firefox, thought not necessarily in that order?

But even that isn't enough to completely fix it. Likely, it would come back as soon as I start playing audio from more than one application at a time.

When playing audio from another application, it would work for a few seconds, and then one of the applications would stop working. Almost like the audio device had become usable by one application at a time (like in the early ALSA days prior to pulseaudio becoming common). And probably if I stopped the other application, it usually wouldn't stop working again until repeating the above steps.

But playing with it some more (with both quitting applications, killing pipewire-pulse over and over), I was eventually able to get audio to consistently work again (ie, normally) for about the last 30 minutes or so.

I tried logging out and back at one point... That didn't seem to fix it either. It wasn't until several (or a bunch more) killing pipewire-pulse, restarting firefox and audacious a few times (I could try other software too!) that it started working again.

I'm leaning toward this being a pipewire-pulse issue at this point... but it's possible that there's a driver issue that causes pipewise-pulse becoming wedged, and that running tas2781-2dev-on.sh and killing pipewise-pulse I'm eventually able to get things into a good state.

If this happens again, I will conduct more testing... And I say if, because I think Ubuntu 24.04 is out today, and if it is... I will likely upgrade. If this is a software issue, good chance 24.04 won't have this problem. I'll report back with my results either way.

Anyone else tried killing pipewire-pulse when having issues?

I didn't see any sort of run away processes, I simply did "ps paux | grep pulse" and that was the only process that showed up so I tried killing it. It was just a guess from remembering all the early pulseaudio issues from over a decade ago. :D

Here's my info for convenience:
Kernel 6.8.7
Kubuntu 23.10
Running with KDE+Wayland

My pipewire-pulse info:

apt policy pipewire-pulse
pipewire-pulse:
  Installed: 0.3.79-2
  Candidate: 0.3.79-2
  Version table:
 *** 0.3.79-2 500
        500 http://us.archive.ubuntu.com/ubuntu mantic/main amd64 Packages
        100 /var/lib/dpkg/status

I didn't have this problem with the older kernel 6.7.x series, but maybe there was a pipewire-pulse update that happened? Or and update to a package it depends on?

Finally, I've attached the requested dmesg output. My audio problems started after 10:30 (maybe around 10:40-ish?) and my audio had been completely working for around...

[dreamsyntax (dreamsyntax-linux-kernel-bugs)]

> Kindly follow Comment 872 to force tas2781 to work

I had been using 6.7.9 for the last week with no issues.
I upgrade to 6.8.7, and within 3 minutes audio broken.

I save your script and run it
-- su root
-- ./tas2781-2dev-on.sh

Sound works again, however:
- sound is notably louder compared to 6.7.9
- right inside / right speaker? (not sure if there's 1 or 2) is louder than on 6.8.7 with your script.

After a few minutes, once again audio will break again, until I re-run your script.
Interestingly, after second run of script the audio balance is fixed. Both left/right speakers sound correct instead of being right-side balanced.

Unfortunately, breaks soon after.

For me audio never lasts more than ~3min.

I also notice that the audio levels will oscillate occasionally on 6.8.x kernels, where this does not occur on 6.7.9.

If there is anything more I can do to help, please advise. I can try any combination of kernel/patches if needed. I just want to resolve this issue without beings stuck on 6.7.9 kernel.

Again for my posts, model is:
Lenovo Legion Pro 7i (Gen 8, 2023) - and alsamixer shows ALC287 under system info.

I was able to get my sound working by logging out and back in.

After I got it working, I ran this:
lsof -p3468 | wc -l
1013

I wonder if it was around 1024 before I logged out..?

The open file limit for the process is: 1024

This explains why "killall pipewire-pulse" would get my sound working again for a single application... It was freeing up one file descriptor.

Is this a pipewire bug, a tas2781 driver bug, or a bit of both? I think if this were a general pipewire issue, we'd be hearing a lot more complaints...

After logging in, I tried this:
systemctl restart --user pipewire

This resulted in a new pipewire process and only 25 open file descriptors. Wonder if this would have fixed the issue without logging out? Something else to try next time.

Next time this happens, I'll see if I can figure what all the file descriptors are for.

For others having this or similar trouble, see if you're having similar issues with pipewire (or perhaps even pulse) and file descriptors.

/var/log/syslog is another valid place to check for these messages (at least on Ubuntu).

Hey all, I'm on the Lenovo Legion Slim 7 Gen 7 AMD version from 2022, and all of a sudden, after upgrading my Fedora install to 6.8.6-200.fc39.x86_64 my audio works! Not sure what happened on that front, but figured I'd stop back in and update.
