Im playing a song right now on my iPhones iPod, but can someone tell me why it is only playing out of the left speaker? I've tried at least 10 songs now and sound is coming loudly out of the left speaker, and some is coming out of the right speaker, although it is extremely faint. Anybody know why? Is there a slider to control the output (left/right) of your sound? Or is there a problem with my iPhone's external speakers?
