Hi,

I've just updated my system today and the built-in laptop microphone disappear from sound applet in KDE.

These were the packages updated:

After updating I've rebooted system and got a nice alsa coredump.

It looks like the mic is being detected on boot.

Could just be a logic rerouting in terms of profiles. What's your

arecord -l
pactl list-cards
pactl list-sources

The alsactl coredump, while I can reproduce, should not be inherently problematic (... that runs for restoring the volumes of devices).

FWIW: https://github.com/alsa-project/alsa-lib/issues/142 but the patches discussed there should be shipped in our alsa-{lib,utils} versions.

Looking at the issue on GitHub, it could be the same problem.

I am getting the message alsactl cannot find hw:0 and daemon deactivates with no devices showing. Downgrading to 1.2.4 solves the problem.

This is from my boot logs:

alsactl[755]: alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HD-Audio Generic at 0xfd3c8000 irq 108)

V1del · 2021-06-07 12:29:24

looks like some alsa-ucm-conf logic mismatch, does it work again if you force it to be used

pacmd set-card-profile alsa_card.pci-0000_07_00.6 output:analog-stereo+input:analog-stereo

in case it does, you can as a workaround add that line without the leading pacmd to the end of your /etc/pulse/default.pa

Not entirely sure whether this mismatch is a bug in the new alsa-lib or in pulse's config parser in conjunction with alsa-lib.

pacmd set-card-profile alsa_card.pci-0000_07_00.6 output:analog-stereo+input:analog-stereo

It changed the profile but the sound applet on KDE doesn't show a microphone as always.

pavucontrol shows microphone as disconnected with no other option in the dropdown selector.

@V1del would you mind to move the post to "Laptop issues" forum? I think it's going to have more attention there.

Hello.
same thinkpad model, same problem.
Headset mic work and mute-led work.
I've edit /etc/pulse/default.pa and uncomment line 39, delete all from ~/.conf/pulse/* and restart.
Now mic is showed (gnome settings), but not working mute-led.
Now led is always on (alsamixer did not follow mute...) and I do not know if work (not tested 'cause use headset, but I want everything to work!!!! )

PS: tested led by

echo 0 | sudo tee /sys/class/leds/platform\:\:micmute/brightness

and

echo 1 | sudo tee /sys/class/leds/platform\:\:micmute/brightness

My LED is always ON (as when muted). Pressing the key doesn't change state.

There's an interesting thread in Lenovo forums going on that kind of resembles the same. Someone suggests there was a problem already with the mic, even if it worked as in my case:

When your MIC is connected to the internal HDA codec, that's a bug on your box too.

Hi, Same problem here on T14 Gen1 AMD:
- No microphone input available in gnome or pavucontrol
- The mic led is not usable (but works if toggled through @gca commands, also possible to activate with alsamixer)

I purged the config of pulseaudio and reinstalled it, with no success. The recent update to alsa-utils 1.2.5-3 did not fix these problems.

Unlike https://bugs.archlinux.org/task/71175 I do not have a segfault, but instead I get this error:

Same problem as described by OP on T14 Gen1 AMD.
Tried manually specifying hardware id in /etc/pulse/default.pa with alsactl restore, after that gnome sound settings show input mic but still can't record anything or see any audio signal there.

 alsamixer -c 1

Mic is also visible in alsamixer and LED can be controlled from there but mic doesn't work.

Hi, same issue as described by OP on T14s Gen1 AMD:
- no microphone input shown in pavucontrol

Did not attempt any fixes as the other users before me have already tried some fixes and had no luck. Scouring through Github and found this though
https://github.com/alsa-project/alsa-lib/issues/148.

The issue you linked says a fix is in alsa-ucm-conf, however this fix was merged after the 1.2.5 release of 31 May 2021. Version 1.2.4 was released in October 2020, so it may take a few months before this fix gets released, so for me it's worth relying on just making this change manually.

I got my microphone functional (without the LED) on a T14 AMD Gen1 by editing the file /usr/share/alsa/ucm2/HDA-Intel/HDA-Intel.conf directly, changing the number 3 on the first line to the number 4:

$ cat /usr/share/alsa/ucm2/HDA-Intel/HDA-Intel.conf
Syntax 4 # This line was edited: this used to be a 3

Define.Use ""	# a non-empty string to use UCM configuration for HDA devices

I can confirm this solves the main issue here but I still can see errors in the logs that didn't happen before. As noted by @tulcod LED doesn't work. Mine is always ON.

I can also confirm this fixing the main issue for me, and as others reported the mute-led is now on all the time.

Yes, led is fixed

talhah · 2021-06-13 12:52:02

Just an update, everything is now working as it was before. Microphone is now detected and the mute-LED is also working. This thread can be marked as solved.
Edit: This issue is not solved, the mute LED indicates the status of the external headset rather than the internal microphone.

Now not working bluetooth headset. Led volume and mic are fixed. Enable/disable work osd. But sounds not working.
Too many problems with last updates... pulseaudio is broken with alsa 1.2.5. Actually only normal headset with jack working correct and with led status....

After updating today mute LED went OFF. Still doesn't reflect real status of microphone but at least button toggles ON and OFF.

Mentioned alsa errors in boot logs are yet present.

update: after poweroff/poweron, mic went ON again. this is weird
