Well, VolumeControl is defined in libmyth.so, but it should all be 
correct.  I didn't deliberately remove it...

Not sure exactly.  I'm just working on rewriting the mythmusic audio 
output anyway, but perhaps someone else could take a quick look at this 
for a quick fixup.  I'm sure that it must be a change to the 
libs/libmyth/libmyth.pro file in the main myth code.  Revert any changes 
to "volumecontrol.cpp or .h" and see if this fixes it.
