Sound issue HELP! 2006 audi a6 3.2
 

I had a issue with my battery draining, it happened to be a bad satellite radio module. Instead of replacing I had it bypassed, because I never used it. Not too long after the bypass the sound from my passenger side speakers stopped working. My drivers side works just fine. Tried disconnecting the battery no help. Any suggestions? Btw I had my amp replaced by audi about two years ago.
