It appears to be a race condition between logind/inotify and pipewire/wireplumber.

Jul 12 10:12:16 localhost.localdomain wireplumber[2315]: activate profile: off (0) When switching active sessions, logind adds and removes "uaccess" acls for sound device access. pipewire listens to inotify ATTRIB events on /dev/snd/* and checks for accessibility there. The order of those ATTRIB changes appears to be random, and some combinations result in wireplumber trying to enable devices before they're completely accessible. Specifically, if /dev/snd/controlC0 is made accessible before the others, it breaks. If it made accessible last, it works. This can be reproduced manually by assuming the role of logind and setting acls manually: # Break access -> audio disabled setfacl -m user:linux:- /dev/snd/* # Grant access in the working order -> audio works again setfacl -m user:linux:rw- /dev/snd/{pcm,hw,seq,timer}*; sleep 1; setfacl -m user:linux:rw- /dev/snd/controlC0 # Break access again -> audio disabled setfacl -m user:linux:- /dev/snd/* # Grant access in the broken order -> audio still broken! setfacl -m user:linux:rw- /dev/snd/controlC0; sleep 1; setfacl -m user:linux:rw- /dev/snd/* So pipewire needs to check for accessibility of more device files. I'll file a report upstream. -- You are receiving this mail because: You are on the CC list for the bug.
