Hello William, hello the usability team,
We are still early in the 2.25 release cycle and I think this is the
right time to discuss the future of the Sound Preferences and Volume
Control, in a PulseAudio world.
I had a quick look through usability-list archives and didn't find
the subject discussed, please correct me if I missed a discussion;
and please do note my comments are based on a snapshot I built
yesterday.
Anyway, I'll dive into the matter and point everyone to the currently
developed gnome-volume-control (hosted in gnome-media/ repository).
Here is how it looks like:
