Internal microphone does not work with 5.12 (Tiger Lake, X1 Nano)

Internal microphone does not work with 5.12 (Tiger Lake, X1 Nano)

[Nico Schottelius]

Hello,

it seems that the internal microphone does not work anymore with
5.12.6/5.12.7. I am somewhat sure it used to work within the 5.11.x
series and that sound did not work at all on 5.10.

I have uploaded the hardware information on

http://alsa-project.org/db/?f=f1a2b32db122695b2cf736db27cb6ed2fa8a9042

The microphone of a plugged in headset however *does* work.

Is this a known bug/regression and is there anything I can do to debug
it?

Best regards,

Nico

Could you check, if the Intel SOF driver is enabled in your kernel?

CONFIG_SND_SOC_SOF_TIGERLAKE

Just checked, it was disabled. I rebuilt 5.12.6, rebooted, but now the
sound card is gone (no device files in /dev/snd anymore), proably
failing due to:

it seems more kernel config options are missing. Distribution kernels 
typically enable all the machine drivers, but you are specifically missing
CONFIG_SND_SOC_INTEL_SKL_HDA_DSP_GENERIC_MACH=m

Distribution kernels are a good reference when building on your own, and 
we in SOF also maintain example kconfig settings for typical systems. 
Here's the bit for systems with DSP and HDA codecs:

I've enabled this one and all machine types and indeed the card is being
recognised (report at
http://alsa-project.org/db/?f=5cbe7c293cbb80ab548b892cfc8b991476b0b2aa).
I checked permissions on /dev/snd, which looks good.

However, obs does not list the microphone at all and
chromium / jitsi shows the snd-hda-dsp mic, however does not let me
select it.

So with above options:

- playback works
- microphone does not work

I have used the .config from the linux-edge kernel from Alpine Linux as
a basis. The above configuration looks to be enabled in my .config as well.

Alpine's default config might include a bit less options than other
distros, I am currently in touch with the developers there for patching
it, as soon as I got the sound card properly working.

Best,

Nico

ok, that's great so the driver appears to work now. You could try
to do simple arecord test in terminal:

arecord -fdat -vv -Dplugw:0,6 -c4 /dev/null

You should see vumeter activity from the built-in microphone.

If that works, this starts to go a bit outside the scope of this list, but 
it sounds something in Alpine's user-space integration is missing. In e.g. 
Fedora and Ubuntu, ALSA UCM file is provided for these platforms and the 
shipped versions of Pipewire/Pulseaudio can expose the devices correctly 
to apps. You can do a sanity test (of your hardware) by booting a recent 
live image of either distro.

That does not work:

[15:55] nb3:~% arecord -fdat -vv -Dplugw:0,6 -c4 /dev/null
ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM plugw:0,6
arecord: main:830: audio open error: No such file or directory

However, recording with audacity produces to results:

- no sound recorded by default
- sound recorded when I plugin an external headset

And using arecord -fdat -vv -c4 /dev/null (without -Dplugw) I get
output, but the level is always 00% without the headset, ranges 02 ~ 90%
with the headset plugged in.

I was wondering if there's a hardware switch "broken"
for the detection of the headset and that's why the mic is muted
internally?

typo: you need to use plughw:0,6 or just hw:0,6

No, the DMIC has nothing to do with the headset, it's an independent 
interface.

I am not sure if this is related to the MIC not working:

[  160.122834] snd_hda_codec_realtek ehdaudio0D0: didn't find PCM for DAI Digital Codec DAI
[  160.122837] snd_hda_codec_realtek ehdaudio0D0: ASoC: error at snd_soc_dai_startup on Digital Codec DAI: -22

[  160.122884]  HDA Digital: ASoC: failed to start some BEs -22

I posted the full output on
http://alsa-project.org/db/?f=45fc657ecf37976734035202625a3c08841d7361

Firmware wise I downloaded the sof firmware from
https://github.com/thesofproject/sof-bin/, I am not sure if the "unknown
sof_ext_man header" message could be the problem:

[   48.431640] sof-audio-pci-intel-tgl 0000:00:1f.3: Firmware info: version 1:7:0-47d07

[   48.534529] sof-audio-pci-intel-tgl 0000:00:1f.3: Topology: ABI 3:18:1 Kernel ABI 3:18:0

I also verified: the microphone of an external headset still works - so
basically the behaviour is the same as without the sof module.
