I have set up my Sky Q remote to operate the volume and mute functions of previous Naim, Marantz and Cyrus amps. However, my latest flame - Quad Vena 2 Play - will not play the game. The Sky set up routine and suggested codes do not let the Q remote control volume/mute. Has anyone done this with a Vena? If so, what code set (4 digits) worked for you?
