need help…

I just purchased a Pioneer DDJ SX and installed the driver and Serato DJ. I launch Serato DJ an turn on the DDJ and all is good as far as the software recognizing the controller. The problem is that only deck 4 will play and nothing else. When I load a track into deck 1 2 or 3 there is no sound. Only plays in deck 4. What am I doing wrong. I did try to reinstall Serato DJ, no luck. I’m on a PC.

Screenshot of your audio settings?

when I click on the audio settings in Serat DJ all I see is an adjustment for Buffer size.

I got it. I reinstalled the drivers, now everything is working.
