Comment:
I don't know whether its worth adding further comment to this or not
since it's been forwarded upstream, but I encountered the same issue
today.  I have been using the 'Kresky Lines' icon theme for a number of
days and the volume icon was visible.  I downloaded a number of updates
today and then after they were installed I noticed the disappearance of
my volume applet.  Some searching on the Ubuntu Forums turned up someone
with a similar problem and they described how they had changed themes
and 'rediscovered' their volume applet.  Following this advice I was
able to find mine again.  I'm a little mystified as to why it worked for
a week and then stopped working.
