I've been having a really annoying problem with my audio lately, it'll just stop working completely and the only way I know how to fix it (temporarily) is to run:
systemctl --user restart pipewire wireplumber
systemctl --user restart pipewire wireplumber
which erases all my volume settings each time.
Sometimes my audio will just randomly cut out, but the more reproducible ways it cuts out are when I reconnect my headset, or my computer hibernates.
