This is weird, if I have earbuds plugged in and nothing is playing (no audio) then I pull up the keyboard I hear a static pop and same when I take it back down. If music has already playing while I'm doing this no static, so I guess it's only when the DAC activates that it plays this static, I can't notice any static in my music or anything only when I first start up a sound when there was none. Not a gigantic problem but it is fairly irritating, I am running 7.0.3 and haven't updated out of fear of a less stable system. Anyone know what this? I recall some static popping I believe on my 4s but I don't think it was quite this noticeable, anyway, anyone know? Also I should note there is a slight wiggle with the headphone cable while it's plugged in the jack, but when I twist it and press it to either side/wiggle it there's no change in sound or anything so I don't think that's a problem.
