Could it be related to that? => After update, pipewire needs to be restarted often
I had problems where my audio suddenly stopped working and Discord was the cause of this. Audio usually worked fine but when I had Discord running and didn’t play audio for a while all audio was broken.
I fixed it by setting ["api.alsa.headroom"] = 512 (Here is a guide on how/where to set this property => https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Troubleshooting#underrununderflow-and-broken-pipe-errors)
