I have a TCL 65R635 Roku TV attached by eARC HDMI to a Sony STR-DH790 AV receiver with an HDMI 2.1-compliant cable -- HDMI 4 on the TV, ARC/eARC output on receiver. TV input to the receiver comes through my Comcast Xfinity set-top box, and I prefer to use the Xfinity XR15 remote unless I am switching among Roku channels.
Paired with my previous less "smart" Samsung TV, the volume and power controls on that remote controlled both receiver and TV. I re-paired it with the TCL TV, but power control is now weird: when both are on, I can turn both off. But the next "power on" from the Xfinity remote now turns on only the receiver THE FIRST TIME I TRY IT... then if I power off and on again, IT TURNS BOTH ON.
HDMI CEC function is properly set on both TV and receiver as far as I can tell. Is there any way to restore the "both off/on with one click on one remote" I used to have?
