Oh... I see the problem in my previous logic now... the media player
reconnects as a *different* client (and a different sink-input). I was
wondering, is this because of the alsa API not having a client/sink-input
abstraction (and my usage for alsa-pulse for playback)? I took a brief look
at the alsa PCM API at
http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html ... and it does seem
to be the case from whatever I could tell.

Hmmm... that's too bad. Do you think directly supporting the pulse API in
the application will do the trick (along with the module I described
previously)?
