pioneer dj sb3 sound problems

I have the pioneer ddj sb3 connected to a peavey triflex also connected to an hp windows 10 lapop. I had sound coming out of it once and it stopped. I updated the drivers as instructed and now I do not have sound. Everything works the controller lights up and responds to the program and vice versa however I am not getting sound from serato. When I test the speakers through the control panel I can hear the test sound. I really need this issue solved in the next 10 hours.
