DDJ-SB No audio

Hi guys, I have a problem with my DDJ-SB. I'm was using it in the last night without any problem. I power off my laptop and go to rest.

Today, I power up my laptop, open Traktor and there is no sound in headphones or RCA output. DDJ-SB Controls works perfect but I don't have sound. Audio settings and output routing are ok in Traktor.

All knobs and faders are in correct position also.

Which may be the problem?

Thanks!
