Mixvibes Control Pro and Traktor Pro Scratch 2

I am trying to set up the Mixvibes with Traktor and I am having problems getting the cue to work.
I am able to use the cue (aka the monitor output on Traktor) if I use the analog outputs, but I want to use the front headphone jack from the Mixvibes for the cue. How do you do this with Traktor Pro Scratch 2?
