CD player has power, but no sound comes out??

My wife and I just purchased a 99 vlx sunsetter with what I assume is the stock cd player. When I turn the "stereo" knob, the cd player lights up and seems to function properly except for the fact that no sound comes out. Since the unit is getting power, it makes me think all of the fuses are fine. I unplugged and then plugged back in the wiring harness, but that didn't do anything. I've also tried turning the stereo knob and both accessory knobs as well. That didn't do anything either. All equipment is stock. No additional speaks or amps have been added. Any thoughts?
