iPod will not play sound.
My iPod will play no music or anything that has sound, so no vid capability either amongst other things. It does on occasion decide to work but only very briefly. I get the error message (-12746) when I attempt to play any music which is what I primarily got it for. It also makes a noise which sounds very much like static although not so often at the moment. It is up to date with iOS 9.2.1 and I have tried everything I can think of. Taken it back to factory settings many many times, and every combination of resetting that I can think of. It has never worked satisfactorily but for some time now it is useless to me. I would very much appreciate any help whatsoever.
iPod touch, iOS 9.2.1, 5th Gen
