Can confirm. My system’s audio is also broken right now. No audio devices detected. checking the pipewire service shows that it’s enabled and running

Edit : Fixed by following the suggestions in this thread on reddit . TLDR ; Replace /etc/pipewire/media-session.d/media-session.conf with /etc/pipewire/media-session.d/media-session.conf.pacnew if you have it in the directory. If not, nuke the whole /etc/pipewire folder and reinstall pipewire (and all the dependencies)
