I have an identical issue with my SANSA mp3 player. When the screen backlight times out [user setting to 20 sec] the squeal stops. Apparently, the backlighting frequency is horrible for our ears. I pick this up over the plane audio, my car and stand alone ear buds. After 20 seconds, no squeal.



Some units are set to remain lit if on external power, so the squeal never stops. 

 Can the screen setting be changed on his iPOD to a shorter time?
