My Headphone Cue is not working when installed into the controller?! (DDJ-400)

I have been using the decks for months now but always through my lap top which worked perfectly fine and i could hear the next song I'm cueing. As I was trying to do a live stream, and obviously I had to connect audio output through BlackHole and Obs, therefore, I couldn't hear anything from the lap top, I had to move to the controller. Now the real struggle began because i can't do the live stream because i can't hear the next song I'm cueing from the decks!
