USB Audio Interfaces & Audio FFT Not Working?

[Culturecide]

I'm trying to get my USB 2.0 e-mu 0404 to output the audio from a DJing program (Traktor) and for Resolume's Audio FFT to analyze it as well.

But it seems I can only get the dinky internal soundcard in my laptop to be recognized by the Audio FFT in Resolume, and not the USB audio interface.

There is also no option to select the stereo mix or wave in volume control for the e-mu 0404, those are only options for the built in "SigmaTel"...

Anyone with an external USB 2.0 audio interface manage to get it recognized by the Audio FFT analyzer?

Thanks
