I'm wondering whether the following is possible and would be really grateful for your feedback.
I've got my laptop running four channels of audio from Ableton into my Native Instruments Audio 8 DJ external sound interface. Those four channels are then sent as four stereo pairs into my Xone mixer. All good - everything works up to this point.
What I'd really like to do is take the master output from my Xone back into my laptop, either via the external soundcard or directly into the laptop, and send it out via the laptop's USB speaker which is actually a dongle that sends audio wirelessly to the amp that's on the other side of the room...

I just can't figure out the right audio routing for this though.
The Audio 8 comes with a bare bones driver that doesn't include a mixer application, so I'm guessing I have to do it with XP's audio setup. I've tried loads of different combinations, but no success so far.
Any ideas? Is this even possible?!
