Weird. I think this is PulseAudio's responsibility but how that relates
to Wayland is not obvious. One possible explanation is the number of
libraries/plugins used internally in the audio system that try to
connect to an X11 server (I don't know why but they do). Starting
recently mutter/gnome-shell does not have Xwayland running all the time
so random library components are failing to find an X11 server. Seen
also in bug 1949200.
