issue with preview and playback?

i recently purchased a new laptop and im having some trouble getting my dj control instinct set up properly.

im trying to have the master sound come from my speakers, while being able to preview in my headphones. for some reason i dont have the option to do both at the same time. i can only use my headphones if theyre plugged into the instinct but then i cant get any sound out of my speakers, and if get playback though my speakers, it seems like i cant preview.

everything works fine with vdj, but not in djuced.

if it matters i am using windows 10, and my old laptop was windows 8.
