So, I added some new stuff to gnome-volume-control. Didn't commit yet, since I don't know in what freezes we are right now (I've been pretty much inactive for quite a few weeks already). The result is pretty sweet, since we now support all ALSA controls (see bug #150158 for patches), but the resulting UI is horrible. Please, UI people, give gnome-volume-control some love [/lame try to get others to fix his own bugs].
