I tried using the "secret screen" and enabled AVR codes. Unfortunately, none of the 4 offered code sets worked with my 6-year-old, high-end, Pioneer Elite SC-91 (which is apparently a little older than CEC). I even tried different regions, and updating OTA. No-go. Strange, since Pioneer is a major player in AVR's and they don't have that many code sets out there.
Very disappointing that Roku is so limited. My TiVo remote has no issues controlling the Pioneer.
Thanks for the post.
Please be aware that Roku remotes do not support AVR control. Roku remotes only support TV volume and power.

This thread was a godsend to those of us who use CEC from our remotes to control AVR volume control. Roku continues to insist this isn't something they support, strangely enough. (I think someone at roku needs to buy an android device and reconsider that...they support AVRs awesomely)
But with OS10, CEC volume control broke (volume up works, down doesnt - both onkyo and denon AVRs that I've tested).
OS10 also removed the menu in the platform secret menu that was used to turn CEC control OFF as well as ON.
Prior to OS10 this was:
So my question: How do we turn this mode OFF now if we have it turned on and want to turn it off?
Ideally we could still turn it back on, too, but I doubt that will be an option, so I'm sure this is a one-time change and we lose functionality that we've had since at least 2013 when I bought my first roku 3.
(and no, I can't use ARC and plug the roku into the TV, or have my TV control my AVR via CEC. my 2007 plasma doesnt support those options)
