Since dropping my iPod, I can only hear music, but no vocals My iPod fell on the ground this morning. Since then, I can hear the music but not the singers anymore! It sounds as though they were in the next room during the recording. As I listen almost only to Podcasts, it's a real problem, because I almost hear nothing except jingles...

Has anyone a clue about the problem I'm facing? Is this a software or a hardware problem?
It looks like a Hardware problem with the mini Jack. Apparently one of  rings is not connecting properly, as if it was not fully plugged in. Make sure it is, try moving the mini Jack in circles and rotating, and see if that makes any difference.
