Hi there, I was using a cheap Dell PC before and connected my microphone to the red plug at the back. The old Dell has 3 plugs (red, blue, green). Now, I got a Precision and there are only two plugs at the back (blue and green). My mic doesn't work in either and there is no red, how can I use the mic?
