I did not install pipewire, so we can exclude this.

In alsamixer and aplay I can see the device as "Generic_1", and -- after finding out the pcm name of it via aplay -L -- I could play some wav file with aplay on it: aplay -D front:CARD=Generic_1,DEV=0 some_wav_file.wav It seems to be a pulseaudio problem, which seems to arbitrarily ignoring Generic_1 card. > Alternatively, take a look at this method of controlling the order in which > audio modules are loaded: > https://wiki.gentoo.org/wiki/ALSA#Laptops_with_HDMI_audio_output Thanks for the link, brought me to inspect /etc/modprobe.d/alsa.conf. Corrected the number of sound cards there, but did not help :-( I remember to have edited this file about 10 years ago, not sure if those settings are still relevant. Cheers, Alex
