I have the CQ18t and monitor quite a bit through headphones. Unfortunately the headphone arming doesn’t persist when I power the unit off/on.
For example, I’ve armed the USB channel to monitor through headphones. When I shut things off and come back and power them on again, I have to re-arm that channel just to listen through the headphones again 
It’s one of the few settings that doesn’t seem to persist. Is there a reason for that? Could we build that capability in?
