Lenovo Thinkpad X1 Carbon 7th gen, no soundcard detected, ChromeOS 87 rammus

[umasse]

Hello, I am running ChromeOS 87 with brunch on Thinkpad X1 Carbon 7th generation. Most things work well, but I can't get audio to work. The soundcard was difficult to get it working properly on Ubuntu 20.04, and only on Ubuntu 20.10 is working well.

The lspci output: 00:1f.3 Audio device [0403]: Intel Corporation Device [8086:9dc8] (rev 11) Full lspci here: lspci.txt

And here is dmesg output:

[sebanc]

Could you try the new "brunch-unstable" build ?

[umasse]

With the new brunch-unstable build, sound playback works. Microphone does not seem to work, but I have not tried any of the existing microphone debugging options yet. Thanks for your quick reply!

[umasse]

I have tried the internal_mic_fix option in grub, but no luck. I will get dmesg and alsa devices details later.

amixer -c0 output does not show any internal mic, so the instruction:

amixer -c0 set "Internal Mic" toggle

does not work. I didn't see anything that I could toggle with any similar name. I also tried playing with mixer levels with alsamixer -c0, but no change. Internal microphone still doesn't capture anything.

I am attaching full dmesg and amixer outputs. amixer.txt dmesg.log

Let me know if I can try anything else, or if anyone knows where else to look for ideas?

Tried with latest stable. No change with default kernel. No sound card detected with kernel 5.10.

[stucki]

I have a Thinkpad Carbon X1 7th Gen here but did not try to run brunch on it yet. However, there were issues to make the sound card work with Ubuntu 20.04 so this might help here too:

• Install firmware from https://github.com/thesofproject/sof-bin/tree/stable-v1.6 (clone the repository + run ./go.sh to install)
• Additionally, blacklist snd_hda_intel and snd_soc_skl via /etc/modprobe.d/blacklist.conf

If one of these is missing, this might explain why sound does not work for you.

[stucki]

@sebanc Is there any chance to have more commits in this Git repository? I see that https://github.com/sebanc/brunch/tree/r87/firmware-mods/intel/sof-tplg exists but I don't see the details for the change. So maybe it is already up to date, but I can't tell for sure.

Git history would help a lot as it would allow me to submit PRs. We talked about this already in https://github.com/sebanc/brunch/issues/512#issuecomment-688536728, but the situation is still the same...

[umasse]

@stucki With latest stable, sound output works. I only have problems with the built-in microphone. I don't have an external mic for the headphone jack, so I can't test that.

[umasse]

Reviving this issue because one year later, mic still doesn't work. I have tried kernel 5.10, and it seems to work well besides the known microphone issue. Tried disabling Intel HDA using the options, no difference.
