I have read the docs about headphones. I can see the routing. I cannot work out WHERE to assign the headphone out in the routing.
It says in IOS, you get main and headphone outs (if the switch is set not to combine) yet in the routing, I see only off-main-aux 1-2. I do not see where to assign headphones.
Is this an assumed route? Perhaps I need to run the app and discover what is really going on but I am compiling equipment to get programming.
I also do not understand the digital outs over USB. Digital is usually over Coax or light pipe.
