WinXP Mic Tutorial.
For winXP users,
First thing, open up your Control Panel.
(Start > Control Panel. Also, Switch to Classic View, if it isn't already in it.)

*Find the icon. Should be Sounds and Audio Devices or something like that.

*Locate the "Voice" tab, click it.

*Find the "Voice Recording" box.

*Press the drop-down menu, and locate your mic. Mine happens to by USB Audio Device. When you have found you mic, select it, and press "Okay".
Go in-game and test it out. If it still doesn't work, add me on XFire (northsk) and I'll help sort it out.
