Notes on setup and whatever follows

Audio

The audio adapter is not detected, and all input is directed to "dummy" output.

The adapter in question:

dwrob@skamander:~$ inxi -A

Audio:

  Device-1: Intel Tiger Lake-LP Smart Sound Audio driver: snd_hda_intel

  Sound Server: ALSA v: k5.10.0-21-amd64

First encountered after initial Debian 12 installation, and apparently fixed by downgrading to Debian 11. However, it recurred there after a couple of days.

The following configuration tweaks resulted in working audio: 

echo "options snd-hda-intel dmic_detect=0" | sudo tee -a /etc/modprobe.d/alsa-base.conf

echo "blacklist snd_soc_skl" | sudo tee -a /etc/modprobe.d/blacklist.conf

An additional tweak didn't have any effect by itself, but in combination with these other two caused a more or less continuous rushing sound, so don't do this: 

echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf

Follow-up: This is probably an Intel audio adapter issue, and not specific to Asus. See among others https://askubuntu.com/questions/1454347/dummy-ouput-no-sound-ubuntu-22-04-and-22-10. The solution is to install firmware-sof-signed (Bullseye, i.e., Debian 11), but I haven't tried this yet since the system is working correctly this moment.
