EDIT: That card looks like a Creative Sound Blaster X-Fi Titanium Fatal1ty, should be able to find some up-to-date drtivers & management app here
Creative is worthless for their drivers. The last update on those things is from 2008.
OP, install the PAX Drivers for the card and also do this in the creative console -
Go to mixer and mute Microphone (if you odn't need it along with Microphone FP if you have it), along with change Rec to "What You Hear"
You can pickup the PAX drivers over at Hardware Haven
