We use UC Surface to run our system. Thats how we plan on setting all the ear mixes. The only issue is the actual unmuting of the in ear Channel. It doesn't unmute by unmuting the channel on the computer. We have only been able to do it through the Q-Mix app on the phone individually. There is the "Mute All" rectangle in the top right corder of the app and that is what I need to figure out how to unmute through the UC Surface on the computer.
