DDJ-RB No Audio in the headphones

Still not resolved, so posting the message again:

I don't get any audio on my headphones after about two or three tracks played. I`m using DDJ RB with MacBook Air via Recordbox with latest updates installed. Been reading a lot of similar errors on windows, but non for Mac. Here is the print screen of my audio settings. Could you please help me with this issue:
