Previously used Chromecast with Google TV and I was able to setup my remote for power on/off for my Hisense TV but disable TV volume controls as I use a Sonos Playbar. I'm trying to figure out if I can set up my Roku the same way? I'd like to be able to use the remote's power button for my TV power, but not have it control the volume as the volume slider pops up every time even though I have TV audio disabled. I tried the CEC route, but that seems to disable IR completely so I then can't use it to control my Playbar as well. Any help is appreciated!
