In the former case, check whether wireplumber and pipewire-pulse services are running in user mode, % systemctl --user status wireplumber % systemctl --user status pipewire-pulse OTOH, in the latter case (the raw ALSA usage), neither PulseAudio nor pipewire should have been started. If such a process is running, it may block your audio device usage. And, you can check which process uses the devices via fuser command % fuser -v /dev/snd/* -- You are receiving this mail because: You are on the CC list for the bug.
