I appreciate the input. I suppose it would be more helpful if I
explained myself...

I was wanting to continue practicing my programming skills by making
some little apps that might be useful to somebody besides me, and that
wouldn't be too hard to do.  I'm probably already getting in over my
head, but the first thing I wanted to do was make an extension for the
sound properties program (i.e. gnome-sound-properties) to allow it to
directly set up/modify pulseaudio/s daemon.conf file in a safe,
user-specific way (i.e. not system-wide). 

While working on this, it lead me to an idea about including speaker
tests, which then lead me to an idea of trying to implement something
like RealTek does for its newer systems with a (windows only) control
panel. It basically detects whenever you plug in an audio device (i.e. a
speaker, mic, etc) and it pops up, allowing you to configure what to
treat the new speaker as (and set a default behavior for new
speakers/devices, I believe). 

I was hoping I could accomplish something similar (maybe not w/ a popup)
on ubuntu by catching dbus messages about inserted speakers, but as dbus
doesn't issue events for this I was thinking maybe there was some simple
way to enable it...

It now also occurs to me that this might be better asked on the *-dev
lists or something...I'll move my convo there as well, and see if I can
get any info.

If anybody's got any ideas though, I'd be more than happy to hear them!
