This happens daily, and I'm not really sure what causes it, but the UI has zero feedback. Click play. Nothing happens. No audio. No icon change. Nothing. I had to launch it VIA console to figure out what the issue was.
Whilst I'm unsure what the specific issue is, I do know that running
systemctl --user restart pipewire.service pipewire-pulse.service wireplumber.service
Fixes the issue (I can open a new console tab, run the command, alt+tab back, click play and get audio), so it's likely related to one of those services.
However, the UI should give some indication that there is some issue instead of silently failing.
