I appreciate that it is an over the top use case but… if I loaded Roon remote on a DAP, would the physical play/pause and skip buttons control roon or would they just control the native output of the player? I have a dCS Network Bridge and about the only frustration I have with it is the lack of physical remote control. I know there are RPi solutions.
Now I write this down, I have a feeling I know the answer.
This would just be for in the house, so not interested in the ARC implementation.
