Hello, I'm trying to get the Tivo remote to control the volume of my Yamaha RX-A3030. The receiver is in a cabinet, so I need it to work in RF mode. I have tried every code listed for Yamaha in the remote setup on the Tivo Roamio Pro, but none of them work in RF mode. I can only get the remote to work in IR mode. Does anyone know how to get this to work? Thanks!
