Lenovo ThinkPad X1 Carbon 7th Generation built-in microphone doesn't work

[Jonathan Kamens]

The built-in microphone in my Lenovo ThinkPad X1 Carbon 7th Generation doesn't work.

A microphone on a headset plugged into the 3.5mm jack works fine.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Kai-Heng Feng (kaihengfeng)]

IIUC linux-oem-osp1 has more DMIC support from intel-sof driver.

[Jonathan Kamens (jik)]

>IIUC linux-oem-osp1 has more DMIC support from intel-sof driver.

Not only does the oem-osp1 kernel not recognize the mic in this laptop, it also doesn't recognize the speakers.

[Kai-Heng Feng (kaihengfeng)]

Subscribing Hui Wang who works on this.

[Hui Wang (hui.wang)]

@Jonathan,

Don't use the oem-osp1 kernel. To make the internal mic work, we need to integrate UCM files, we are trying to submit the files to ubuntu 19.10, but not finished.

After the UCM is integrated, bot 5.3 kernel and oem-osp1 kernel will work.

[Hui Wang (hui.wang)]

BTW, you could manually copy the UCM and then do a test on internal mic

https://github.com/alsa-project/alsa-ucm-conf/tree/import/ucm

Two important folders are:
https://github.com/alsa-project/alsa-ucm-conf/tree/import/ucm/sof-skl_hda_card

https://github.com/alsa-project/alsa-ucm-conf/tree/import/ucm/LENOVO-20QE000VMC-ThinkPadX1Carbon7th-20QE000VMC

[Paolo Mainardi (paolomainardi)]

hi everyone! Are there any updates on this ? Are the changes been integrated into 19.10 ?

[Hui Wang (hui.wang)]

The ucm is not merged yet, just wait for a while.

[Alexander Fieroch (fieroch)]

Any updates on this as now in times with corona people could use the micro for homeoffice video calls...

For the manual way - what has the user to do in addition to copy these UCM file directories?

[Hui Wang (hui.wang)]

Here is a step by step guide I found: https://www.sysorchestra.com/setup-soundcard-and-microphone-on-lenovo-thinkpad-x1-carbon-7th-gen-with-linux-mint-19-3/

[Martin Seener (martinseener)]

Hi @humbell,
yeah i wrote this back in january when i freshly got my X1C7. It still works pretty good for me now with the -40-generic kernel. Newer kernels currently don't work and/or breaking reboots/sleep.
I will also wait for @hui.wangs new kernel and libasound2 and test this locally.
Using Timeshift to back to my working environment if needed. Hope we can get this one finally fixed for everyone with default packages and without hacky stuff.

[Alexander Fieroch (fieroch)]

I tried kernel 5.3.0-43 from proposed but my notebook does not wake up from S3 suspend anymore (Lenovo Carbon X1 7th gen). It was working with kernel 5.3.0-40...

I recognized some errors regarding this sound update package in journallog. Maybe this causes suspend not to work?

full journal log with kernel 5.3.0-43-generic

[Hui Wang (hui.wang)]

Alexander,

Looks like your sof-firmware is not same as the one on my machine (/lib/firmware/intel/sof|sof-tplg). Where did you find it? The sof-firmware on my machine is installed with linux-firmware of 19.10.

[Alexander Fieroch (fieroch)]

Hm, previously I tried the script at #12. Maybe this is a firmware relict?

[Hui Wang (hui.wang)]

The 5.3 kernel can't work with the sof-firmware-1.4.2. So please have a try with the linux-firmware of 19.10.

[Paolo Mainardi (paolomainardi)]

Hi everyone again, i am experiencing some APCI issues using 5.3.0-40 with sof drivers activated. It happens, almost randomly at this stage that the system is not waking up after a sleep, initiated by Gnome, what i see is just the fn led active on the X1-carbon-7h.
It seems that disabling sof and loading the standard kernel modules (the blacklisted ones) the problem disappear. I saw that in 41 and 42 there are some ACPI-related fixes, but suddenly they broke the mic.

[Paolo Mainardi (paolomainardi)]

Can we have a quick write-up of everything needed to test these fixes ? From UCM to Kernel updates, just to have a standard procedure and avoid configuration issues.

[Martin Seener (martinseener)]

Would also be interested how to come back from my hacky solution to the default one. If the new kernel and packages are available in the stable branch i would also try to fix it myself and write a small guide. I can use timeshift to go back to my working version if i f**up.

[Paolo Mainardi (paolomainardi)]

hi @hui.wang, can you confirm that thoses steps https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1859754/comments/48 are not needed anymore now because everything is upstream ?

[Hui Wang (hui.wang)]

@Paolo,

Those steps are still needed even they are upstreamed, the step1 (enable bionic-proposed) is not needed.

[Paolo Mainardi (paolomainardi)]

Thanks @hui.wang.

I am still having s3/sleep blocking issues, basically with the sof driver activated and all the kernels > 40 i cannot have the system back from sleep, is there something i can use to debug this ?

[Hui Wang (hui.wang)]

@Paolo,

Did you try the kernel 5.3.0-43? If you uses -43 kernel and the system still couldn't sleep, please upload the dmesg with -43 kernel.

[Jean- (jean-helou)]

Hi,

I wanted to give a bit of feedback after a few days using the laptop with kernel 43 and the experimental libasound packages from Hui's ppa.

As far as I can tell, the microphone works flawlessly.
Sound output to speakers and HDMI works too. With one notable drawback : the internal speaker volume, even when maxed out in alsamixer and gnome settings is very weak, much weaker than when using the snd_hda driver. I think this is related to https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1859754/comments/28 and one should be aware of it before switching to sof.

Plugging a BT headset correctly switches output to the headset and joining a google meet visio conference in firefox switches the microphone too.

As reported in https://bugs.launchpad.net/ubuntu/+source/alsa-lib/+bug/1859754/comments/86 the chrome snap seems to do something different from firefox ending up in crashing the BT headset when joining a google meet visio.

[Hui Wang (hui.wang)]

It is the problem of 5.3.0-45 kernel, please try with -46 kernel.

[Jean- (jean-helou)]

Damn sorry about that, I didn't notice the kernel moved from .43 to .45. I'll try with 46
