The next time you hit this issue, please provide the output of these commands,
$ journalctl --user -u pipewire -u pipewire-pulse -u wireplumber -b $ pactl list sinks $ wpctl status $ pw-cli list-objects Node $ pw-dump Since you said you're trying to restart *pulseaudio*, I'm concerned you might have conflicting sound servers running (although your package list suggest not), but to be sure, $ ps aux | grep -E 'pulseaudio|jackd' Shouldn't report anything (other than grep). If that doesn't help provide any further clues, debug logging from Pipewire and friends will be required. For the pipewire daemon in particular, $ export DEBUGINFOD_URLS="https://debuginfod.elfutils.org/ $DEBUGINFOD_URLS" $ timeout 5 strace -f -tt -T -p `pidof pipewire` > pipewire_strace.out $ timeout 5 perf record --debuginfod -g -p `pidof pipewire` $ perf report > pipewire_perf.out If you have custom configuration configuration of Pipewire share that too.
