Notes on setup and whatever follows
Audio
The sound card is not detected, and all input is directed to "dummy" output.
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
