So my iPad 3rd gen. Sometimes will just start making weird sounds. Like the lock sound will be longer then normal but sound sorta like a radio but messed up. No sound will sound the way it should. It only goes away when I turn off my iPad. It's really weird but I think it's just iOS 7 cuz it didn't happen before iOS 7 never. I'm using iOS 7.0.4 does this ever happen to you Thank you for your response.
