UR824 Line Out settings

Is there a way to get Windows to recognize the 3 other stereo outputs, (3/4, 5/6, 7/8)??? I’d like to be able to use the other outs as sources for other applications like Skype without having to use the Loopback feature. I mean, it some what made sense that I go into the dspMixFX and in the output routing set the Line Out 3/4 to Mix 1 L/R thus having all of the audio from Ch. 3 and 4 going to the main out but that doesn’t work.

Any thoughts on how to do this?

Also, do I need to setup Windows to recognize those other outputs? If so, how?
