I have been playing around with mine for two days now and I am getting frustrated. When I play music through headphones there is a pop before the song starts to play. I have tried all of my sets of headphones and they all do it. When I have the unit set up with audible screen taps and the like I also get a crackle and pop through the headphones. Is anyone else having this issue? I like the tablet itself but I may have to return it.
