Thanks Daniel.

Those with Roku's like Ultra and use av receiver volume instead of the tv. And still want to use the Roku remote, there is secret menu to switch the Roku remote from controlling only tv's to av receivers and soundbars.

press the Home key 5 times, then FF once, Play once, RW once, PLAY once, and FF once, then go to RF remote menu option. IR transmit menu, querying avr's (instead of tvs)

Now when you go to program the tv:

settings> remote & devices> remote> remote in USE> program tv> choose to change brand. now audio brands are listed
