I have a 2GB Clip that works in all ways except I can't turn up the volume.  If I push on the down volume end of the bar, I get the display with the little speakers at each end and the bar is empty indicating 0 volume.  If I push on the volume up end of the bar nothing changes.  If I start by pushing the volume up end of the bar, I don't the display with the little speakers at each end.  Is the volume up switch dead?  Anyone else have this problem?

The 15 second reset has no effect.
