Every time I plug in a mic, I get static as output. I can barely her my own speech and it sounds robotic. The static stays even when I mute the mic and goes away only when I unplug it. Already tried reinstalling drivers and windows. The microphone works on other computers.

PC specs:
Model: Alienware Aurora R4
OS: Windows 7 Home Premium 64x
CPU: Intel Core i7-3820 3.60 GHz
MB: Stock Alienware motherboard
GPU: GTX 660 2x in SLI

Thank you in advance!
