My Powertab no longer produces sound. It plays fine but there is no sound whatsoever. And no it has nothing to do with my speakers, or does it?

I can play through itunes and media fine etc. If anyone knows the answer or can give me any advice i'd be very greatful. Thanks

this happens to me sometimes on my guitar pro. i just go into volume control and a slider called "sw synth" will be all the way down. just turn that up. hopefully that should work.
that used to happen to me i'd work when i restarted my computer though
