no sound driver since 5.3.0.42 kernel

[schmidt]

no sound driver since 5.3.0.42 kernel, 5.3.0.45 kernel doesn't solve the problem. i have only a dummy soundcard. no sound.
5.3.0.42 kernel works fine.
my sound card is intel 100 / c230 hd audio

[Hui Wang (hui.wang)]

some fixing patches are in the 5.3.0-43, but somehow they are not in the 5.3.0-45. I just checked the 5.3.0-46, those patches are in the -46 kernel.

So please use -43 kernel or wait for -46 kernel.

[schmidt (schmidt01)]

(Had an fault in my first post. I meant -42 & -45 have sound problems, -40 works fine)
I installed -43 kernel -> same problem, no driver. Will wait for -46 kernel and post if I have still problems

[Hui Wang (hui.wang)]

@schmidt

-43 kernel doesn't work? Could you please upload the dmesg with the -43 kernel.

[MMason (mmason11)]

I am using kubuntu 19.09 and intel HD sound drivers with nvidia , was working perfectly.

I tried, ubuntu 20.04 live , my sound drivers was not working. So I thought there is driver issues with sound.

today I updated my kubuntu and I have 2 kernels

My sound drivers works, has no problem with kernel:
5.3.0-40 (good)

Dumb Audio (no sound at all) in
5.3.0-45 (problem)

Input : intel smart sound Technology TSS
output : Realtek High Defination audio.

So now in the boot of Grub, I choose advance, then old kernel..
Sound just works fine that way.

[MMason (mmason11)]

Additionally : I tried 5.3.0-42

My sound drivers works, has no problem with kernel:
5.3.0-40 (good)

Dumb Audio (no sound at all) in
5.3.0-42 (problem)
5.3.0-45 (problem)

[schmidt (schmidt01)]

I use ubuntu 18.04, today I installed -46 kernel, unfortunately no sound

[schmidt (schmidt01)]

I've to revise it was to fast, I also updated pulseaudio, now I have also no sound on the -40 kernel, argh!

[schmidt (schmidt01)]

so, now again, I restored my pc: -40 works again, -46 no sound. I put a screenshot of installed packages with pulseaudio, it seems also some problems.

[schmidt (schmidt01)]

installed packages

[Hui Wang (hui.wang)]

@schmidt,

Please upload the log of "lspci -nnvv". And you could temporarily use a workaround "options snd-hda-intel dmic_detect=0" in the /etc/modprobe.d/alsa-base.conf.

thx.

[schmidt (schmidt01)]

here we come

[Hui Wang (hui.wang)]

@schmidt,

Got it, the legacy hda driver found the dmics on your machine,it aborts the probe, but the pciid is not in the sof driver, the sof driver is not loaded.

You could workaround it by adding "options snd-hda-intel dmic_detect=0" in the /etc/modprobe.d/alsa-base.conf temporarily. I will submit the patch to fix it.

[Hui Wang (hui.wang)]

@schmit,

Could you please test this kernel https://people.canonical.com/~hwang4/testdsp/, remove the dmic_detect=0 workaround, and download all deb and sudo apt install *.deb;reboot

thx.

[nukedathlonman (areginato)]

I've just recently run into this on my Acer Swift 5 - works on 5.3.0.40, doesn't work on 5.3.0.42 or 5.3.0.45. The work around works, as does not using the work around with patched kernel 5.3.0.46 provided here.

[schmidt (schmidt01)]

@Hui Wang
great job, it works!

[schmidt (schmidt01)]

now I installed ALSA Packages post #11, now I have sound but the control for sound is gone and hardware keys for sound doesn't work.
Should I open a new Issue request?

[MMason (mmason11)]

@Hui Wang

Hello

for Acer Switch 7, given kernel; " 5.3.0-46 generic #38 testdsp SMP "

worked for me. I have my sound back. thank you.

[nukedathlonman (areginato)]

Notified of update today, and noticed one of the updates was for Kernel Image 5.3.0-46. So I removed the testdsp SMP kernel today and installed 5.3.0-46 proper kernel: Intel HDA driver not loading (so dummy output). So I'm back to workaround from 12.

[MMason (mmason11)]

not related to kernel but for information; Today I tried Kubuntu 20.04.

workaround of post #12 does the job.

[MAR (mattmax42)]

With kernel -46 sound output is working again, input is still not. The machine also still freezes on wake from sleep and requires alt+sysreq+B to force a reboot. Reverting to -40 again for now...
Dmesg attached for troubleshooting.
Regards,

Matt

[Hui Wang (hui.wang)]

@MAR,

if you add snd_hda_intel.dmic_detect=0 in the bootargs, does the -46 kernel still freeze when waking up?

[Hui Wang (hui.wang)]

@schmidt

"now I have sound but the control for sound is gone", is it a regression from -40 kernel?

"and hardware keys for sound doesn't work", is it a regression from -40 kernel too?

Please upload alsa-info.txt with the testing kernel. (run alsa-info to generate the alsa-info.txt).

thx.

[MAR (mattmax42)]

@Hui Wang
Thanks for the advice, yes with the snd_hda_intel.dmic_detect=0 bootarg, the freezes are resolved. The kernel messages contain a lot fewer errors too... So does this would suggest that the culprit is loading the drivers for the DMIC?

[Hui Wang (hui.wang)]

@Mar,

Probably. Could you upload the version of the linux-firmware? and md5sum /lib/firmware/intel/sof/*
and lib/firmware/intel/sof-tplg/*

[Hui Wang (hui.wang)]

@Mar,

the firmware on your machine is for ubuntu 20.04, with the ubuntu 20.04, you should not install the 19.10's kernel. please install 5.4.0-18 or later kernel.

for sof driver, the ubuntu 19.10's kernel can't work with the 20.04's firmware.

[MAR (mattmax42)]

Ah yes, that was a leftover from an attempt to fix this a few weeks ago and forgot about it. I downgraded to 1.173.17, which seems to be the latest in bionic and tested again, same problems remain. New md5sums below:

[MAR (mattmax42)]

Should have mentioned, I'm on bionic (Linux Mint 19.3) so 5.3.0-46 is the latest kernel available for the distro.

[Hui Wang (hui.wang)]

@MAR,

If sof driver could load the firmware and tplg successfully, it will not have freeze issue on waking up. It is weird that your machine has this issue. Is it 100% reproduced on your machine and what brand and model is your machine?

[MAR (mattmax42)]

@Hui Wang,

Having tested it a couple of times now, it is somewhat intermittent. Without the kernel parameter (#23) set though, more times than not the machine will freeze on wake from sleep. It is a Dell 7591 2in1. I know of others with relatively new machines who have had issues with DMICs not being recognised but their solutions have not resolved the problem on this particular model. I have attached a new dmesg, in case it's helpful.

[schmidt (schmidt01)]

@Hui Wang

here is ALSA Info

http://alsa-project.org/db/?f=1a8674718418d75435a2e95e80eacd235338f835

[Hui Wang (hui.wang)]

@schmidt,

According to the alsa-info.txt of #33, I couldn't find anything wrong, the driver already worked and mixer controls already generated. I have no idea why "the control for sound is gone and hardware keys for sound doesn't work". With this testing kernel, the audio should work as before.

[schmidt (schmidt01)]

@Hui Wang

it looks like kernel isn't a problem, 'cause it isn't relevant wich kernel I load, I've this problem since I install this packages - post #11. So maybe not your code section

[schmidt (schmidt01)]

@Hui Wang
yesterday installed -47 Kernel, also no sound. (Don't know if already patched new Kernel)

[[e-mail] (vijayaavaas)]

same dummy output to laptop speaker problem here as well. manipulated alsa mixer, force reloaded alsa, purged and reinstalled alsa as well. nothing happened. it started after the network upgrade from 19.10. it was working well before upgrade. still working fine in earphones though. i an on Toshiba Satellite L500 machine.

[Hui Wang (hui.wang)]

Please upload the dmesg, alsa-info.txt and the log of 'pacmd list' if you have this problem.

thx.

[schmidt (schmidt01)]

@Hui Wang
upgraded to 20.04 all works fine
