I have a Mic and I've tried both my front panel mic in jack and the pink one on the motherboard. When I plug it in, Realtek HD Audio Manager pops up and I select that the device is "mic in". The mic appears in devices and printer section of the control panel, and also appears in device manager, with fully updated drivers. However, I record and no sound works, nothing is being recorded. I have tried the mic in other computers and it works fine. It's a 3.5mm plug.
