CUE MONITORING(need help!)[FOUND]

Hi people! this is one my first post here as I'm relatively new at djing but recently I just switched from a laptop to a desktop and my headphones cue monitoring doesn't seem to be working the way it used to work with my laptop and I'm so confused
I use the U-Mix Control Pro
I connected the L/R cables into output 1/2 and connect them to my external speakers directly
I connected the usb power cables into my desktop CPU
I have installed the driver for U-Mix Control Pro
I'm currently using CrossDJ2.3.0
when I plug my earpiece into the port and I press the headphone monitor button, it won't work
only the master output is coming out of my speakers and I can't monitor using my earpiece
Please help! once again, I'm quite new and I'm not very good with wires actually x.x any advice will be greatly appreciated
