so when i plug my ipod into my iHome iH9 thats right next to my head and i lay down to go to sleep i can hear the speakers making this incessant pitter patter sound. its very quiet but i can still hear it over my fan. i only hear it when the ipod is plugged into it the iHome. why does it do this? it also happens when its plugged into any other power source and i got head phones or portable speaker plugged in. the only way to stop the pitter patter is to take the ipod out of its dock and put it back without touching the screen. i use my ipod as my alarm clock so i need it in there. anyone else hear this?
