Windows 7: Fatal1ty Gaming Headset, you guys know this

Hello,

I'm new and I just bought a Creative Fatal1ty Gaming Headset with mic, and the mic doesn't work! I heard you are supposed to let the computer know you want it analog, and not digital or something, but I don't know how to change all this.
I know very little about computers but the problem with this mic is not that I did not switch it from Mic-off to Mic-on, or that I have the volume of. I'm not a fool.
I just don't know about computers so I need your help cuz you guys know.



Pretty please with sugar on top, help me
Xx

Bump, also got probs with this. The mic works, but the sound is very unclear, and I can hardly hear my voice(when I record myself). It's alot of buzzing, extremely irritating.

Here you go, a clip, you can hardly hear my voice there. This is so frustrating, have been toying with a lot of settings but it is no go.

Yey, I solved it. Just had to fix the mic-boost settings. See pic.

I know! did the same! haha
