Newish PC bought here 1 month ago I plugged in my new headset Senheisser PC 360 into the front two audio/mic ports on the FRONT of the coolermaster case above the DVD drive and oinly the audio port works.. whats up with this? Then when I plug the headset to the back of the case suddenly the mic starts working? So the front mic port isnt working or isnt turned on? Whats up with that?
