I'm also on Ubuntu 20.04 and able to switch to PipeWire recently using pipewire-debian PPA [1]. Just a note in case you're running into an annoying issue like me: make sure your /etc/pipewire directory is EMPTY before installing pipewire. Mine somehow didn't, and pipewire just hang due to using the old config file. Took me a while to figure out the issue. After installing pipewire packages, make sure to copy the most recent config from /usr/share/pipewire into /etc/pipewire before enabling all pipewire services (this should be covered in the linked guide). https://pipewire-debian.github.io/pipewire-debian/ https://pipewire-debian.github.io/pipewire-debian/
