Hello guys, I can use your help again. 
 
My g/f and I just got a webcam and now we want to use Skype along with it. We both have microphones, but we can't get them to work. 
 
I have a 5.1 sound card, the booklet says I should plug the microphone into the center/subwoofer output. But it's not working, no matter what I try with the software... I tried to detect a mic, but doesn't work. 
My g/f has the same problem, we found an old (bit crappy) mic, but it doesn't detect it. 
I also saw audio ports in her PC, I tried both. 
Help please!!! 

 I don't want to waste my money on a USB mic!
