There are a couple variants of the new enhanced (Wi-Fi) remote with the added TV power and volume buttons. The 2017 Streaming Stick/+ remote just has the voice search. Only the 2017 Ultra remote has the headphone jack private listening, remote finder, and gaming buttons.
Will either new remote work with the 2016 Ultra, older Roku 3, etc?
Can the new remote with headphone jack also work with the new SS/+?
When will Roku start selling them as extra accessories?
How do the TV power/volume buttons work? Continues to rely on the Roku player to send HDMI-CEC commands, or the remote itself sends (auto-programmed) IR codes? Both methods have been mentioned in the press.
Can the new remotes work with an actual Roku TV? I assume the factory enhanced remote that comes with a Roku TV performs the TV power and volume controls via a more direct method over Wi-Fi? Plus it has a mute side button in addition to Vol +/-.
P.S. The Roku website's new comparison chart hasn't been updated to show 2017 Roku TV capabilities (the chart only mentions the 2016 TCL UP130 4K non-HDR Roku TV model).
