I bought a GE PC Stereo Headset Model# 98960 headset from Target a few weeks ago and have just finally gotten around to using it. the headphones work fine on it and the people in my TS server i can hear talk. But the thing is that I cant talk in any of my programs. Wow chat, Vent, TS, and sound recorder all are not picking up my mic. and when i go down into my sound options under 'recording' i have these and I dont understand them.

Microphone

SPDIF

Working (this is defaulted right now)

Line In

Could someone help me out?
