My radio appears to be working but I get no sound from the speakers. on 2000 Chevrolet Lumina

the theft loc is not engaged from what I can tell, it's not asking for a code, the stations tune and display, clock functions and it appears the head unit works as it should in all aspects but I can not get any sound across any of the speakers at all. One day while switching the ignition off from run I got static across the speakers for a fraction of a second. Can it be a faulty ignition switch causing all the problems? The car starts and runs fine.

Get a extra speaker and wire it to an existing speaker to check if the old ones are bad first.
Turn the volume up!
If equiped, does the cd player/volume work ok?
