[Dell XPS 13 9343] Audio broken with I2S mode

[Jared Dominguez]

Please read this first before considering making a comment:
The root cause of the scope of this bug report was caused by a BIOS error in BIOS A01 that put the sound in an undefined mode that wasn't really I2S and wasn't really HDA. This has been fixed by BIOS A02 ( or later ).

There was an _REV patch that was proposed but not merged upstream. If that (or something similar to it) does get merged upstream, then with BIOS A02+ the audio will operate in I2S mode.

If you have a problem with your computer, please do not make comments here, as this bug report is considered closed. Instead file a new report following https://wiki.ubuntu.com/ReportingBugs . Your issue will not be dealt with by making comments in this report, and will likely be completely ignored.

(This is a public bug report for LP1402828.)

This system has a dual-mode audio with an HDA and an I2S interface. Which shows up depends on the reported _OSI from the last cold boot. Since the kernels in Ubuntu 14.10/15.04 (15.04 uses 3.18 currently) report an _OSI of "Windows 2013", I2S mode is used for audio.

A workaround is to pass acpi_os="!Windows 2013" as a kernel parameter, but this is non-optimal since the mode of the touchpad is affected. It also results in an alternate, less used and tested path in the firmware to be used.

See the attached dmesg log for details on where the failure happens. Notably,

$ dmesg -t | egrep "(audio|snd|INT3438)"

There's also a failure to load the codec firmware after a suspend/resume.

No audio still with kernel that was linked above (3.19rc5). The behavior in dmesg output does change a bit though.

Which codec is used on this platform ? Is it Realtek ALC286S ?

There are some bugs cleanup recently and the latest driver is available here:
https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git/log/?h=for-next

Could you try this kernel ?

[Tom Li (biergaizi2009)]

Hello everyone.

I was hit by a smiliar bug on Thinkpad Helix 2, and I file an upstream bug:
https://bugzilla.kernel.org/show_bug.cgi?id=92061

Here are some progress to share, after of all, you need the a firware
/lib/firmware/intel/IntcSST2.bin

It was added to linux-firmware git repo in Dec, 2014. So most of the distro packages
haven't included it yet. Fetching for yourself.

So all you need to do it:

1. fetching the fireware and putting it to the correct directory
2. poweroff (not reboot to make the audio device reset completely)
3. Booting with latest 3.19 RC kernel

[Liam Girdwoood (lrg-r)]

I see this in the dmesg :-

[ 7.955515] rt286 i2c-INT343A:00: Device with ID register ffffffff is
not rt286

and this comes from :-

regmap_read(rt286->regmap,
                RT286_GET_PARAM(AC_NODE_ROOT, AC_PAR_VENDOR_ID), &ret);
        if (ret != RT286_VENDOR_ID) {
                dev_err(&i2c->dev,
                        "Device with ID register %x is not rt286\n", ret);
                return -ENODEV;
        }

This means we are not reading the RT286 codec ID correctly over I2C. I have no access to this HW so can
someone check the BIOS settings for RT286 and make sure it's enabled in I2S mode.

[David Henningsson (diwic)]

Hi,

Can we also get a confirmation from either Dell or Intel (I don't know which one is the correct to ask) about the firmware - is the firmware to be loaded onto the ADSP the IntcSST2.bin file that was upstreamed into linux-firmware in December 2014, or does this platform require a special firmware for some reason?

(Setting to incomplete while waiting for Dell or Intel to answer)

[Andon Todorov (andon-2)]

According to the Dell website/driver download this is a ALC3263 chipset from Realtek.

[Mario Limonciello (superm1)]

Yes, it's a Realtek ALC3263. The real problem may be that it's trying to
use rt286 codec driver which doesn't actually have support for the ALC3263.

ALC3263 runs in dual mode HDA or I2S similar to rt286 though. When _OSI
test for "Windows 2013" returns TRUE the codec will be put into I2S mode on
the next cold boot. There is not a toggle in the BIOS to change I2S/HDA
modes manually.

[Liam Girdwoood (lrg-r)]

Ok, a missing ALC3263 codec driver would explain no audio probing. I'll contact Realtek and see what the schedule is for ALC3263 support.

[Liam Girdwoood (lrg-r)]

Realtek say ALC3263 should use the same driver as RT286. I've asked Realtek for a patch to fix the probing.

[Andon Todorov (andon-2)]

It looks like probing might be already there:

https://github.com/torvalds/linux/blob/master/sound/pci/hda/patch_realtek.c

static struct alc_codec_rename_pci_table rename_pci_tbl[] = {
{ 0x10ec0280, 0x1028, 0, "ALC3220" },

{ 0x10ec0288, 0x1028, 0, "ALC3263" },

I am unsure if this snippet is relevant here.

[Keyon (yang-jie)]

David Henningsson (diwic) -- we use the unified FW file --IntcSST2.bin that was upstreamed into linux-firmware in December 2014--for different broadwell platform(with different codec).

[Andon Todorov (andon-2)]

Tom Li (biergaizi2009) :

I tried your method of downloading IntcSST2.bin from : http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/intel/IntcSST2.bin

I still have the same issue after cold reboot of my XPS13 2015 9343

An update to the symptoms with acpi_osi="!Windows 2013" boot param:

-Microphone does not work , but there is output sound

[Jared Dominguez (jared-dominguez)]

Building with the ASoC for-next branch[1], I get what's possibly slightly improved results:

[Jared Dominguez (jared-dominguez)]

Andon: Nope, same thing with those commits.

[Samuel (samuelspeer)]

I'm having the same issue. When I install 14.04.1, sound works (3.13 kernel). When I manually update to 3.16 kernel to fix touchpad issues, it breaks the sound. When I do a vanilla install of 14.10 (3.16), no sound at all. I guess I should try 3.15 and see if I can get both working!

[Shih-Yuan Lee (fourdollars)]

I just tested the mainline Linux kernel 3.19~rc7-vivid in Ubuntu 15.04 and the followings are the result.

[Shih-Yuan Lee (fourdollars)]

I also found the similar error message in the kern.log of comment #17.

rt286 i2c-INT343A:00: Device with ID register ffffffff is not rt286

[Shih-Yuan Lee (fourdollars)]

After checking linux/sound/soc/codecs/rt286.c, the ID register must be 0x10ec0286.

[Shih-Yuan Lee (fourdollars)]

I made a patch to skip checking ID register for v3.19-rc7.

[Shih-Yuan Lee (fourdollars)]

However it becomes worse.

[Sam Gaus (gausie)]

fourdollars: your kernel param

> acpi_osi=! "acpi_osi=Windows 2013"

Doesn't look right, unless I've misunderstood!

[Shih-Yuan Lee (fourdollars)]

@Sam,

I want to force the Linux kernel only to accept "Windows 8.1" probing.
https://www.kernel.org/doc/Documentation/kernel-parameters.txt

It seems the BIOS will probe "Windows 7" first and then "Windows 8.1" no matter if "Windows 7" is probed or not.
And Linux kernel will accept any OS probing if it is in the following table.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/acpi/acpica/utosi.c#n87

[Shih-Yuan Lee (fourdollars)]

I can see the following message when I installed "Windows 8.1" in the system storage, and then booted Ubuntu vivid live system by the USB stick.

rt286 i2c-INT343A:00: Device with ID register 10ec2088 is not rt286

[Shih-Yuan Lee (fourdollars)]

However 0x10ec2088 is not supported by the Linux kernel v3.19-rc7.

https://github.com/torvalds/linux/blob/v3.19-rc7/sound/soc/codecs/rt286.c

[David Henningsson (diwic)]

There is a lot of activity going on in the rt286 driver at the moment. This one looks particularly interesting:

[Shih-Yuan Lee (fourdollars)]

Yes, I hope it can be merged into v3.19.

[Andon Todorov (andon-2)]

Has anyone tried a combination of https://bugzilla.redhat.com/show_bug.cgi?id=1188439#c25 trackpad fix and the alsa patch mentioned above? Any luck?

[Niccolò Belli (niccolo-belli)]

As far as I know the audio patch doesn't work.

[Major Hayden (rackerhacker)]

I tested David's rt288.patch above on 3.19-rc7 and it had no effect on the audio problem. I tried it with and without reverting the i2c IRQ patch that fixed the touchpad.

[matze (matthias-ruegge)]

I found a workaround which reduces the problem. The microphone is still not working. I installed the mixer pavucontrol. In the configuration tab I switched off the HDMI profile. See attached screenshot. Now the speaker is working fine for me.

[Shih-Yuan Lee (fourdollars)]

There is a patch for 0x10ec2088 but it is not included in https://github.com/torvalds/linux/blob/v3.19/sound/soc/codecs/rt286.c.

[Niccolò Belli (niccolo-belli)]

Does latest patch work?

[Shih-Yuan Lee (fourdollars)]

No, there is some obscure BIOS/EC implementation that refuses to enable I2S audio mode for Linux kernel.

[Shih-Yuan Lee (fourdollars)]

I saw 0x10ec2088 in the latest kernel tree of https://github.com/torvalds/linux/blob/master/sound/soc/codecs/rt286.c.
It should be included in the next v3.20 release.

[Major Hayden (rackerhacker)]

I'm building with those new SoC patches now. My first couple of builds didn't work out and I discovered that my .config didn't have modules enabled for some of those SoC audio codecs. I'll hopefully know something more soon.

[Andon Todorov (andon-2)]

@rackerhacker : Any success?

[Major Hayden (rackerhacker)]

@Andon-2 -- I wish I had better news. :/

Long story short, I was able to build a 3.19-ish kernel with some additional ASoC patches earlier this week and the card showed up on the I2S bus with full input/output capabilities. However, whenever I played sounds, I never heard anything. PulseAudio showed data going into the card (signal levels were moving), but nothing was heard via speakers or headphones. I dug into amixer to figure out if something needed to be unmuted or an amplifier switched on and found nothing.

I tried with a newer kernel last night but there are some serious hard lockup bugs in the pre-3.20 patches. I'm now kicking myself for not saving the kernel branch that I had the other night. :/

The contact at Realtek feels that there's either a BIOS update required or one small option on the card isn't enabled. I'd like to test again but the kernel is a bit of a mess as of when I tested it last night. Hacking DSDT's won't fix the issue according to someone who has much more knowledge about ACPI tables than I do.

TL;DR:
  - Waiting on 3.20-rc1
  - Card shows up, can't hear anything
  - Realtek gave me some stuff to test

[Alessio Treglia (quadrispro)]

Has anyone tried 4.0-rc3 so far?

[Mario Limonciello (superm1)]

@Alessio, just some updates.

4.0-rc3 still doesn't have everything needed for this.
https://github.com/torvalds/linux/commit/2cc3f2347022969f00a429951ce489d35a9b4ea8
http://mailman.alsa-project.org/pipermail/alsa-devel/2015-March/088724.html

are a start, but there are more pieces missing too.

[Rene Treffer (treffer-3)]

I just got audio (speakers, not mic) to work.

1. Linux has to announce to be ACPI 2.0 complient, see https://lkml.org/lkml/2015/3/12/149
2. I've merged the latest for-linux branch of Mark Brown https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git/

I've published that result to https://github.com/rtreffer/linux to simplify attempts to reproduce this.

[Rene Treffer (treffer-3)]

UPDATE: the mic is working. This was my fault, the controls should be adjusted to Dmic, which seems to refer to the internal / digital mic.

[Mario Limonciello (superm1)]

Rene, it shouldn't be your fault. Even with that collection of patches microphone automatic switching won't work. There's still more to be done.

[Gabriel Lemieux (gabriel-lemieux)]

This bug seem's to hit other computer using broadwell. I got something that's look like this bug on my new HP spectre x360, I followed all step you tried guy's and I didn't succed to debug it. I'm new to bug tracking so, if something is needed, just ask.

Symptoms:
In dmesg I got this message:
# rt286 i2c-INT343A:00: Device with ID register ffffffff is not rt286

After some work I got those messages:
# broadwell-audio broadwell-audio: ASoC: CODEC DAI rt286-aif1 not registered
# platform broadwell-audio: Driver broadwell-audio requests probe deferral

I would be happy to help, and happier to have a correction for this bug ;)

[Mario Limonciello (superm1)]

@all:
This was caused by a BIOS error in BIOS A01 that put the sound in an undefined mode that wasn't really I2S and wasn't really HDA. This has been fixed by BIOS A02 ( or later ).

There was an _REV patch that was proposed but not merged upstream. If that (or something similar to it) does get merged upstream, then with BIOS A02+ the audio will operate in I2S mode. There are still a handful of open issues in I2S mode that can be discussed and sorted out if we come to that.

@Gabriel,
You should file another bug on your model and manufacturer. This is specific to the BIOS and embedded controller implementation in the Dell XPS 13.

[Francisco Cribari (cribari)]

Today I installed Ubuntu 15.04 (desktop edition, 64 bit) on a DELL XPS 13 (9343) notebook. Prior to installing Ubuntu, I upgraded the computer bios do A03. I have no sound. Kernel:

@cribari,

Have you cold booted twice since installing Ubuntu? Cold boot means shutdown in the OS properly and then bootup to the login screen. Do this twice.

[Niels Egberts (nielsegberts)]

@superm1,

I have the same problem. No matter how many times I reboot there is no sound.

[Mario Limonciello (superm1)]

@Niels:

Are you updated to BIOS A03? Also it's not reboot, it needs to be shutdown (as in power off properly from within Ubuntu).

[Jens Grehl (likeluckyjoe)]

My BIOS is updated (A03) but no sound.

[Mario Limonciello (superm1)]

@Jens,

Have you cold booted twice in a row into Ubuntu?

Mario: My sound is working now, awesome!

Not sure if it was an update, of I just always rebooted instead of shutting it down completely in trying to get it to work, but it's working.

[Mario Limonciello (superm1)]

Great! It's the latter. There haven't been any updates to the kernel that
would have caused it to change behavior in 15.04.

@Mario
Could boot didn't helps. Should I modify my alsa-base.conf?

[Mario Limonciello (superm1)]

@Jens,

No, no other changes are needed on the system. If you have the kernel
command line modified in any way, especially acpi_osi options that might
factor in. What kernel are you running? What OS version? Can you share
your dmesg?

The current 3.19 kernel in 15.04 and BIOS A03 has everything that is needed
to make this work properly. It will /not/ work if you switch back and
forth with Windows.

@Mario

I shared my dmesg. I see that my BIOS is A07 instead of A03, which you are tested.
Do you have any idea / solution? Should I downgrade my BIOS? Before with A02 there are no sound too.

[Mario Limonciello (superm1)]

@Jens,

According to your dmesg you aren't running the XPS 13 9343 from 2015,
that's the 9333 from 2014. So this is a separate issue you are having. I
would recommend you contact ProSupport for your issue so they can debug
further.

Hi,

mutliple reboot doesn't work for me (i'm dual booting ubuntu 15.04 original kernel 3.19 and w8.1).

There is also sound issue on Windows (no audio recognized) but disabled fastboot in windows power options fixed that.

[Mario Limonciello (superm1)]

@Marc,
It's not a matter of reboots. It needs to be COLD boot. Shutdown
Windows. Boot Ubuntu. Shutdown Ubuntu. Boot Ubuntu.

@Mario

Sorry by multiple reboot I meant cold boot. Tried again this morning, stille doesn't work for me. ( bios a03 was preinstalled on my xps maybe it could help)

[Seth Forshee (sforshee)]

I've found a couple of times that my audio wasn't working when going back to HDA mode after using I2S mode. I can get it back by opening a terminal, launching alsamixer, pressing F6 and selecting the "HDA Intel PCH" device, then using the up or down arrow to adjust the master gain.

I have no idea why this is necessary, but after doing it once it isn't needed on subsequent reboots (unless I've changed to using I2S audio in the interim).

[paul wall (hektik02)]

Here's what I did to get my sound/microphone working.

It appears ubuntu is loading the wrong module for our soundcard at start so some people dont get sound or get to use their microphone.

Manually load the module as so.

sudo modprobe snd-soc-rt286

goto your sound settings in the system settings and choose your output device and sound should immediately start working as well as your microphone.

you want to have the module automatically load at start up.

sudo nano /etc/modules
add this to the file and save and close it:
snd-soc-rt286

restart your system to make sure sound is working automatically after reboot.

now enojy your sound!

[gobywan (tuttacolpadiafs)]

@hektik02 not working for me, neither right away nor after reboot :(

[paul wall (hektik02)]

@gobywan

after loading the module manually run the aplay -l and tell me your output.

[gianni (gbarberi)]

after loading the module in settings I find only "dummy output"

[David Henningsson (diwic)]

JFTR, it seems that upstream has agreed to revert the _REV change for 4.1, and develop a quirk system for 4.2 that would enable us to stay on HDA mode for as many kernels as we like:

Hi, I have the Dell XPS 13 9343 (2015 edition) with intel audio and BCM4352 wireless driver.

After 3 COLD (shutdown, not reboot) reboot, still no sound :'(
But Paul Wall's trick:

works perfectly

[Mario Limonciello (superm1)]

paul, Benoît,

If you're happy with I2S, then I guess no worry. But if you want HDA working make sure you are on BIOS A03.

[Daniel Millier (danjmillier)]

Just wanted to give my two cents on this bug. I tried a few methods found on AskUbuntu, but now have a "Dummy Output" under System Settings > Sound. This is the output of "aplay -l"

aplay: device_list:268: no soundcards found...

Is this bug still being worked on?

[gianni (gbarberi)]

Well, you're asking, not giving 2 cents....
Same for me
:-(

[Jan Henke (jhe)]

As far as I followed upstream, work is being done on this matter in the Linux kernel, not really in Ubuntu. (Since it is not a packaging bug, but rather a development task)

Current focus seems to be to make sure audio works in HDA mode. I2S mode is apparently improved in kernel versions 4.0 and 4.1, but it is still rather new and not as mature as the HDA code. There is definitely effort in progress on making this work out of the box with the Linux kernel.

For the moment I can just advise to update to the most recent firmware version (A03 at the time of this writing). This gives you working audio in HDA mode. I2S mode audio will be enabled when the code for it is ready in terms of code quality and feature completeness.

[GaryParr (gary-garyparr)]

Does anyone know how to get this issue in front of the Dell BIOS developers? Because I have what appears to be the exact same problem on different Dell hardware...

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1464757

[Jan Henke (jhe)]

@GaryParr technically the firmware is okay. It is the I2S support in the Linux kernel that needs to be finished. We should not encourage firmware trying to distinguish between running Windows or Linux. The current "solution" on the XPS 13 really is just a temporary hot-fix until the kernel support is working good enough.

[Niccolò Belli (niccolo-belli)]

I would like to try again I2S with kernel 4.3-rc2: how am I supposed to force I2S instead of HDA?

[Niccolò Belli (niccolo-belli)]

I asked Rafael J. Wysocki about it:

Hi,

You need to recompile it with the config option unset.

acpi_rev_override is for systems other than the XPS that may need the override.

Now that I'm thinking about it, though, it may be useful to ignore the XPS' blacklisting for acpi_rev_override=n. May cut a patch for that ...

[Jared Dominguez (jared-dominguez)]

Chris: I'm well aware of the newer BIOS versions. I work at Dell on Project Sputnik. The issue is that the I2S audio mode is not well supported. There is now a quirk in the Linux kernel that sets the ACPI _REV reported to the firmware to 5 only if on certain systems needing to be quirked. (Setting _REV to 2 results in our firmware configuring audio the same way it would be on Windows 8.1 and Windows 10.) It would be wonderful if this quirk did not need to exist in perpetuity, especially since more and more systems will be using I2S audio in the future.

Vitor,

Check and see if your BIOS is fully updated. If it's updated all the way
try COLD bolting a few times. It's key to be cold booting not rebooting.

Hi Mario! Thanks for the reply! My BIOS is A07, the last one. So, for a cold booting, you mean I need to init 0 my laptop a few times?

Regards in advance! :)

[matze (matthias-ruegge)]

Hi Vitor,

cold boot means. Start from the switched off laptop by powering it on. I am
not sure if init 0 does the same.

Regards
Matthias

I read this on this blog (http://hgdev.co/installing-ubuntu-15-04-on-the-dell-xps-13-9343-2015-a-complete-guide-update/)

No audio

If you have no audio (no speaker displayed in “Sound Settings”) just do two cold reboot (= completely shut down your laptop twice). Audio will work fine after that.

But on my sound settings I have "speakers built in". But still no sound... :/

@Vitor, I think the bug that you are experiencing seems similar, but it is a different one than the one from this bug report. See http://en.community.dell.com/techcenter/os-applications/f/4613/t/19682246

I am experiencing it as well, and I haven't found a solution yet. I hope Dell will have a fix soon, in their forum they mention that they are looking for a fix.

[Francisco Cribari (cribari)]

I have a DELL XPS 13 (2015 model, 9343, bios A07, currently with Gnome + GDM). I had audio problems with Ubuntu, then with Fedora and now with Arch: https://bugs.archlinux.org/task/49556 .
