logitech Gaming Headset not working in CSS

Hi, i just bought a pair of Digital Precision PC Gaming Headset from Bestbuy. this pair however is not USB only Mic. and Line-In cord. the headset works with AIM, Yahoo Messenger, Etc. but with CSS(Counter Strike Source) doesn't seem to work. this is the only game i've tried it on and it seems to fail. i tried the headset test under options and all came out good. i heard my voice as i spoke but when i'm in a server that has ALLTALK Enabled i can't seem to talk to anyone. what could be the problem?

[EDIT] it's FIXED

Hi New_Age :)

Glade you got your headset sorted, Counter Strike Source...luv it ;)

Can I ask what you had to change??
