Hello All, My 3rd gen Ipod Touch, whether I am playing a game, or watching a video, or trying to listen to songs...will proceed alright for about 20 seconds, then the "normal" volume turns into an ear piercing screech... You can no longer hear the regular audio, this screech replaces it. I immediately turn the volume all the way off. It does NOT do this if I am using my headphones. The Ipod does not have water damage, has not been dropped, no screen damage, etc. I've had it for about a year now and this problem cropped up probably a couple months ago. I appreciate any input...thanks!
