iPad thinks it is connected to a dock connector = no sound
Over the past few days, my iPad 2 will suddenly lose sound. When I check the audio output, 'Dock Connector' is always checked. Unfortunately, I don't owe any dock connector nor has my iPad never been connected to one. I read elsewhere that this may be a 30 pin connector issue. I tried cleaning the 30 pin connector slot out as suggested elsewhere but it didn't really help. The issue usually resolves on its own but it is annoying nonetheless. Anyone else having this problem & how did you resolve it.
