I have a tivo edge and trying to setup the remote to control the volume of the Arc. The Tivo remote works just fine with my TV - turns on and off and selects the input without issues. The remote uses IR. To program the remote to control the arc, the Tivo instructions are to select a A/V device from the Tivo remote setup menu and try the different codes to see what works with the Arc. There is not an option to select any Sonos codes, so you apparently must use a code from another brand, My research says thet the Denon codes work with the Arc - but not mine! I have tried all the Denon codes and none of them work.
My remote is in IR mode and has new batteries. How do I set up my TIVO remote to control the volume of the arc.
