S4 external Audio Interface Issues

Hello everyone,

I have a Traktor S4 mk2 and recently purchased a Focusrite Scarlett Solo audio interface. I was hoping to use the Solo so that I could use my monitors for both mixing and as the speakers for my computer (the monitors are the outputs of the Solo). Unfortunately, assigning the Solo in as the audio in Windows settings does not allow me to run Traktor through the speakers without also assigning the Solo as the audio device in the Traktor software. This works, but it also disables the cue functions and the headphone jack on the controller.

I'm rather green when it comes to this sort of thing, I've used my S4 out of the box hooked directly to my monitors for as long as I have had it, so I think this may be a routing issue that is simply beyond my experience.

Has anyone experienced something similar or does anyone have a recommended fix?

Thank you
