I have my pb for quite sometime now.... The other day i was listening to music uisng itunes and headphones. I got up from my desk and i put the head phones down and decided to listen to music over the speakers. I unpluged the wire. And there was static. It sounded like a blew the speakers, I restarted my computer and it was fixed....... I went to the apple store In cambrige MA, (wow wut idiots) because my ipod battery is dead. (I have to buy a new battery or get a new ipod, what a load of *****) $500 and i get to use it for a year..... Anyway i asked about this and they couldn't solve the issue. The genious said he looked around and some epople had some problems with the sound and 1.5 on pb.... Anyone have this happen to you.
