Charlie: I started this sub-discussion but with the latest upgrade I realised that gnome-volume-control does not work anymore with pulseaudio, so the only two fixes for this bug are: either use pulseaudio in xubuntu, or use a different mixer (e.g. fork the previous gnome mixer applet and maybe call it xfce-volume-control-applet).
Fixing this problem would not help your case: having a mixer applet sitting there, not using 40% cpu, but not controlling anything, is not useful.
