Hi,
This is on a fresh install of Debian 12.0 on a Fujitsu LifeBook U series (Alder Lake), with xfce4.
The sound card is a Realtek ACL257. My internal microphone is detected, but does not seem to work. I can see it in `xfce4-pulseaudio-plugin` and in `alsamixer`, but it just does not record anything. Tried `arecord`, zoom and an online microphone test tool. None of them recorded any sound. The speakers work fine on the other hand.
As far as I can tell all the drivers are installed. Am I maybe missing a setting somewhere? Any help is appreciated.
Thanks

Re: internal microphone not working bookworm
I went to "DebianOn" and searched for your laptop.
https://wiki.debian.org/InstallingDebia ... 1/bullseye
And I found this in the audio section:
First, check if "firmware-sof-signed" is installed.
Then see if that fixes your audio issue, the newer firmware may fix the bug.
If not, try setting the kernel option for the module listed in the bug. (The ~ represent line numbers, do not include them in the file.)
Let us know if that helps.

And I found this in the audio section:
While they claim to have a workaround, it appears that the original issue is still not fixed for that user, but maybe it is possible with the newer firmware available in bookworm.The sound device is:
00:1f.3 Multimedia audio controller: Intel Corporation Alder Lake PCH-P High Definition Audio Controller (rev 01)
Which works with the latest firmware from the SOF project. There is a bug and a workaround to get the microphone working: https://github.com/thesofproject/linux/issues/4099
First, check if "firmware-sof-signed" is installed.
Code: Select all
#apt install firmware-sof-signed
$systemctl reboot
If not, try setting the kernel option for the module listed in the bug. (The ~ represent line numbers, do not include them in the file.)
Code: Select all
#editor /etc/modprobe.d/micfix.conf
~
~#This fixes the microphone issue on my Fujitsu LifeBook U series yyyy-mm-dd
~options snd-sof-pci tplg_filename=sof-hda-generic-2ch-pdm1.tplg
Be seeing you...
Re: internal microphone not working bookworm
Thanks @CynicalDebian, it worked like a charm!
Already had `firware-sof-signed` installed. So, creating `/etc/modprobe.d/micfix.conf` and reloading the module fixed everything. I tested the mic with Skype Online and Online Mic Test, and it's all good.

Thank you very much @CynicalDebian, installing firmware-sof-signed instantly fixed the issue, so confirmed to work also on ASUS Vivobook X712DK_M712DK!
