How do I enable "What U Hear" as a stereo mix?

 

I recently just updated the drivers for my Creative X-Fi sound card because I was going to start broadcasting on Justin.tv. I heard that "What U Hear" is Vista's Stereo mix, but when I put it as the audio device in FME (Flash Media Encoder), I cant hear whats playing on my computer... Any fix for this? Thanks in advance

What U Hear is just another name for Stereo Mix / Wave-out mix used by Creative. The only thing you can do is to play with the settings.
