Headphones don't work on ddj-rb when I use my macbookOS Mojave

Hello

I've used my DDJ-RB on other computers and never had a problem but now with my macbookOS Mojave the headphone output don't work.

I've tried downloading the drivers and uninstalled them then rebooted my computer and installed it after installing I rebooted again my computer and tried opening rekordbox and use it like it should work but it didn't. 

At the audio settings I can't choose the ddj-rb but only my computer.

I've tried everything I found about headphone output that don't work and nothing helped.

Please help me!!!
