Rekordbox sound is always on

Hello!

In two days i will have to perform a little show, but right now my Rekordbox is not wordking fine.

When i have my master, trim and slider on and also the low, mid and high on, it sounds like there is some sort of noise on the background.

When turn my low, mid and high completely off, the song still plays along and a signal is send to my master volume. The link underneath gives a screenshot of the problem.

I already deleted Rekordbox and installed the latest version, bus still having the same problem!
