My iPod recently started having strange problems with audio playback, i have tried several different pairs of headphones and in every pair the right headphone will not work. However, if i pull the 3.5 plugin out from the ipod just a little bit, both headphones work. This gets quite annoying, as it is difficult for the jack to stay exactly where it needs to be. Does anyone have any idea as to how i can fix this? i have attempted updating itunes, the ipod software, restoring the ipod, and have attempted all of these things 2 or more times. Any suggestions?
