While debugging #11, I found that if I didn't have the card plugged in first then it would never be recognised.
The only way that it would randomly be recognised is if I started PA, plugged in the card, then started gnome-volume-control-applet. When the card wasn't "found", the following was produced in the debugger: (gdb) run Starting program: /usr/bin/pulseaudio [Thread debugging using libthread_db enabled] process 3652 is executing new program: /usr/bin/pulseaudio [Thread debugging using libthread_db enabled] W: pid.c: Stale PID file, overwriting.
