I need help figuring out what is wrong with my iPad 2 sound system. I have checked all the normal stuff , bluetooth off , volume up on all , three volume controls. I have lightly brushed the speaker holes with a little soft brush. My wife's ipad 1 blows mine away sound wise. I can just barely make out a video but when I add an external speaker its fine. But should be able to sound lvl the same as the ipad 1 ....any suggestions ? Thanks for taking your time to help !!
