The documentation changes look fine in terms of describing how one
option may influence the other, however there is no explicit mention in
the documentation that selecting a dbus display with no audio backend
will also use dbus for audio.
Is it possible to mention this somewhere? Otherwise someone would have
to go digging through the code to figure this out.
