Problem with audio

I have a 05 Cobalt, and I'm not getting any sound from the speakers. I checked all the fuses that have to do with the audio system, and they are all good. I was wondering if there was any hidden fuses for the speakers, that I don't know about. Any help would be great. Thanks!

Nope, no fuses for speakers on an OEM setup. Provided the head unit powers up and toggles thru the stations, etc, something is unplugged or the HU is shot.
