Public bug reported:
Brand new PC (it is a descktop All-In-One with integrated speakers), no change
to the bios, fresh install with no additional package.
In the "sound" section of the parameters, the output menu has a single entry
"dummy output" and the vu-meter below this menu tracks the input microphone,
which works.
(the UI is in Russian, it's a friend's PC, sorry if the English terms are not
exactly right).
Same with pavucontrol.
Same on ubuntu 20.04 and 20.10.
I first searched the internets and randomly tried the following additions to
/etc/modprobe.d/alsa-base.conf (one by one), none of them worked
options snd-hda-intel model=generic
options snd-hda-intel model=alc274-dell-aio
options snd-hda-intel model=auto
options snd-hda-intel dmic_detect=0
options snd-hda-intel index=2 # tested 0, 1, 2 and 8 -- wish I new what it means
options snd-intel-dspcfg.dsp_drivers=1
I was delighted to hear that Apport could play noise on this machine
because before that I didn't get a click, I was wondering if the HW was
working.
That's all. Bug reports are love letters.
