So I bought a new set earphones and the left ear is a teeny, tiny bit louder than the right (maybe burn-in will fix it?). Until then I was going to use iOS 7's audio volume balance to compensate, no big deal right? Well, the amount I need to move the slider is almost nothing but it does noticeably correct the LR balance, however, in Apple's infinite wisdom, the slider snaps back to center if it's only moved slightly. I now cannot correct the audio balance at all because it keeps moving back to center! WHY WOULD YOU DO THIS APPLE?!?!
