Sound output on iPad

iPad Pro 12.9 is hooked up to Pioneer DDJ SX3 and controller is functional. The sound is coming out of iPad, not the controller and I cant figure out why. My Macbook pro works fine on DDJ SX3.
Also, Jog wheels have no motion on iPad but with Macbook they function fine. Please help.

Is there any update on this topic? I have same issue with iPad Pro 11”
When i am using numark mixtrack pro 2 there is no problem but with Pioneer it seems that ipad cant see it as a sound device so maybe there is a problem with firmware of a DDJ
