budgie bundles https://git.gnome.org/browse/libgnome-volume-control. If I read things correctly, it does not use the system version. It probably should.
There's no system version -- gnome-control-center, gnome-settings-daemon and gnome-shell all bundle libgnome-volume-control using git submodules:

(just checked and indeed there is no standalone libgnome-volume-control lib). I could check with the desktop and packaging lists on this one just to make sure.
