Hi and Help!!

Just bought the ion Discover DJ. Having trouble.
I've added a second sound card - USB Sound Card (XB X-Fi Go). Downloaded and installed ASIO4ALL. I've set the Cross Audio Preferences to Dual Stereo and selected the appropiate resource for the Master and the Cue. basically followed the directions in http://www.mixvibes.com/en/content/cross-dj-faq
HOW DO I USE 2 SOUNDCARDS WITH MY PC ?
to a tee.
No sound will come out of headphones when using ASIO4ALL with XB X-Fi Go and internal soundcard selected. If I unselect internal sound card I can get sound thru Headphones either set as the Cue or Master in Cross Audio Preferences. Also can get sound if selecting XB X-Fi Go from Direct Sound in Cross Audio Preferences.
Need more help.
