Here is a comment from an internet post that may give you a clue as to how BIG a problem this is and yet CHEV has NO recognition of same. Some people have replaced radio and speakers with no result. Still no sound. I would guess it's a wiring related issue.
This is messed up! I've been on quite a few forums about this issue and every single one had at least 20-50 if not more people with the exact problem. My car just started with this issue 3 days ago, I went all over creation (including my Chevrolet dealer) and everyone will either say they do not deal with wiring or it will cost $60-$75 to just have it looked at no necessarily going to figure out the problem
