Dear Debian community,
I'm running Bookworm with XFCE; Linux version 6.1.0-15-amd64
(debian-ker...@lists.debian.org) (gcc-12 (Debian 12.2.0-14) 12.2.0, GNU
ld (GNU Binutils for Debian) 2.40) and since yesterday, I cannot seem to
use the analog audio card any more.
The card isn't showing up in `pavucontrol` or in `aplay` and `arecord`:
```
cgelinek@gar:/tmp$ aplay -l

cgelinek@gar:/tmp$ aplay -L | grep -A 1 default

```
Note that the USB Audio device is a webcam and its microphone is
working. I don't have speakers on my monitors, so I can't test the HDMI
playback devices. The analog devices (front audio, line-in/out) are now
completely missing.
Other debug info:

I.e. that particular error appeared any time between Dec 18 14:42:21 and
Dec 19 13:37:16, but I cannot be 100% sure this is actually the cause of
the missing analog audio.
I also know that I received a new analog headset on Dec 19 between 12:21
and 12:45 and tested it successfully. But at some point that afternoon,
then I noticed that my analog audio wasn't working any more and I
started to investigate, the earliest entry in the journal hinting at
this is:
```
Dec 19 15:22:18 gar sudo[9362]: cgelinek : TTY=pts/0 ; PWD=/tmp ;
USER=root ; COMMAND=/usr/bin/systemctl status pipewire-session-manager
```
Unfortunately, I also did quite a few other things in-between, including
a BIOS upgrade after 12:57 (I needed `dosfstools` to
format the USB drive to store the BIOS), installed `fwupdate` at
13:47:56 and `intel-microcode` at 14:25:40,
so any of these actions could've caused this issue.
Some of these (AFAIR auto-configured) PulseAudio config files are still
pointing to the "analog-stereo" output:

At this point I was wondering about the kernel modules.
As I found on some forums, I also tried adding `snd_hda_intel
dmic_detect=0` or `snd-intel-dspcfg dsp_driver=0`
to/*/etc/modprobe.d/alsa-base.conf*/, but this didn't seem to have any
effect.

suggest the `snd_hda_codec_realtek` module was loading when the sound
was working but now isn't, even through the firmware is installed:
```
cgelinek@gar:/tmp$ apt list --installed |grep firmware
WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.
firmware-linux-free/stable,stable,now 20200122-1 all [installed,automatic]
firmware-misc-nonfree/stable,stable,now 20230210-5 all [installed]
firmware-realtek/stable,stable,now 20230210-5 all [installed]
firmware-sof-signed/stable,stable,now 2.2.4-1 all [installed]
```
As [mentioned on the Debian forums][2], I may need the
/*/etc/modprobe.d/amd64-microcode-blacklist.conf*/ file as I already
have /*/etc/modprobe.d/intel-microcode-blacklist.conf*/, which is in
[amd64-microcode][4] and which I had not installed:
```
cgelinek@gar:/tmp$ apt list --installed |grep microcode
WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.
intel-microcode/stable,now 3.20231114.1~deb12u1 amd64 [installed]
```
But since `amd64-microcode` explicitly points to `intel-microcode` for
Intel processors (which I use), I was hesitant to install it. [This Arch
Linux thread][3] seems to be about a very similar problem, unfortunately
it doesn't include a solution - I already have the realtek and sof
firmware installed.
I also tried booting into a /*debian-live-12.4.0-amd64-xfce.iso*/ system
but that has the same problem (no codecs found!), besides also not
detecting any audio hardware except for the USB webcam.
Any other ideas what I missed or what else to try at this point would be
highly appreciated.
Thanks for your time,
Christian
