I have read conflicting statements on this topic...
The Roku 3 remote has volume control buttons on the side, does it only control volume on particular model TVs? Mine says it is paired, but the volume cannot be controlled by the buttons on the side of the remote.
Will the Roku® Enhanced Voice Remote with TV power and volume buttons - RC463 work to pair and control power and volume? And in that case would the Programmable buttons function?
The Roku 3 Gaming remote will not control tv volume by IR, it may control the tv volume using HDMI CEC. The Voice remote will control many tv brands by IR. Can roku 3 program the 1 & 2 keys, I have no idea, but if the roku 3 responds to the voice control, theres a good chance you can program those keys.
