No sound from ROKIT 5 monitors with DDJ-FLX6

Hi Guys,

I seemingly have everything ready to go, but when I load any tracks I can't get them to play through my ROKIT 5 monitors.  I have the correct outputs in RekordBox preferences. XLR cables from speakers to Master on the controller.  Volume knobs turned up and each speaker volume is at an adequate level too.

I am very new so it may just be a function I'm totally overlooking.

Thank you for any help!
