Appeared when installing system

things that did not work
Deleting ${HOME}/.pulse*
Rebooting.
Other threads i this forum.
this extremely similar problem https://bbs.archlinux.org/viewtopic.php?id=257505
and kinda similar to https://bbs.archlinux.org/viewtopic.php?id=154002
pacman -S sof-firmware
       
Additional infos:

/dev/dsp does not exist.
fuser -v /dev/snd/* returns

                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  qsqcqs     1296 F.... pulseaudio

aplay whatever.wav produces no sound.

aplay -D sysdefault works
because aplay -l returns
