XDJ-RX Performance mode, No sound

Hi Pulse,

I'm trying to use Rekordbox performance on my Toshiba Laptop Windows-7 64bit

I follow your settings from this forum video 

I can control every feature for example: load tracks, crossfader, ect2.. from XDJ-RX however, there's no sound came out from the speakers or the headphone (Sounds normal if I use it alone without laptop).

on the laptop side, laptop sounds come out from the laptop even though I connect it with XDJ-RX (I browse youtube while its playing)

here is my settings:

- From XDJ-RX ( Latest version 1.80 and mixer mode: midi control)

 - From Rekordbox ( latest 4.0.7)

and my computer audio:

Is there any setting that I miss?
