Hmm, if the user plugs/unplugs the cable, my understanding is that David
Henningson's patches for jack detection would trap these events, and
that would trigger reconfigurations of the audio server.
If notifications are needed, that's fine with me, we can add them at a
later stage. I don't have multiple monitors and would not be able to
contribute anything on this anyway...I wanted to start small and make
use the existing information is used properly by PulseAudio/others
