Problem with DDJ-RB

Hi! my problem is that the audio is cut/mute 1 secong several times over a set, I've tried to change the ASIO options of pioneer to 512 (default 244) and the problem persist.

Rekordbox is updated to the latest version and the drivers
just like windwos 10 as well.

My laptop configuration is:

i7 Family 6 Model 94 Stepping 3 GenuineIntel 2.5ghz
8GB Ram
Windows 10 x64
Nvidia gtx 950m
Intel graphics.
HDD

The rekordbox is forced to launch in nvidia card.
The ddj-rb is connected in at usb 3.0 port and the rca 
connect to the active m-audio av40.

i've tried the ddj-rb using it as external sound card
and putting a movie, and it has not distorted.

Thank's.
