I have had a headphone jack problem with my iPad since last July (new in April 2011). Sometimes it works fine, sometimes I will hear only one channel, ie background music but no voice, vice versa, etc. If I jiggle the jack it gets distorted and may or may not help or make it worse
Tried and failed by:
*resetting to original factory settings
*Varied uses of different apps, videos, iTunes store purchases, imported CDs,etc
*Cleaning jack and inspecting for problems with jack
*Three different brands of headsets: skullcandy (with or without mic), apple headset, Sony
*Apple Store genius bar: found no problem with the jack itself and could not replicate the problem entirely although they said one pair of headsets in the back did seem to have the same kind of result. Said they had never heard of anyone having sound issues like this and that the were guessing there was a miscommunication between my Skullcandy headset's mic/remote switch and my iPad and it wasn't picking up the channels correctly so only use a headset without a mic/ remote switch. Well two different headsets later and I am still frustrated by this constant problem. Try watching a movie on Netflix when u have to keep constantly wiggling the jack to get the sound correct. Even when u are listening to the music and it sounds fine, once u move the headset at all the sounds goes in and out or changes volume. I have pretty much stopped using the iPad for anything that needs sound thru the headphones.
I am frustrated that my local Apple store keeps telling me they cant figure out whats wrong, but I can not solve it with new headsets, resetting, etc. Any advice?
Thanks.
