Monday, the Roku engineer spent a fair amount of time troubleshooting with me. We made some findings, but no progress on my particular issue. He needed to consult with others in Roku.
The Roku units (now) only work when connected directly to HDMI-1 on my TV, which is the only port that supports ARC (Audio Return Channel). The issue presents itself on the other HDMI ports, which I usually don't use. However, it is not practical for my home theater configuration to run the Roku through the monitor's HDMI-1 port and route its S/PDIF audio back to the receiver. I'd have to use two HDMI splitters and leave the monitor on when I run the projector.
Since 2021-05-19, my older Sony receiver is no longer recognized as a valid device for the infrared controls, even though they were working for 3 years prior to that date. The Sony supports ARC from its video out to the monitor, and everything was working from 2018-05. I am presuming that ARC is not the issue. I also made some changes in the receiver that did not make any difference.
Whatever happened that affected my environment on 2021-05-19, it seems to resemble a database change that has removed support for some infrared controls on devices or functions. My Harmony still does its thing without issue. Since Logitech has discontinued its Harmony line, I was hoping to switch to the Roku remote. The new Pro remote was awesome, for the 4 weeks I owned it prior to the infrared controls failing. Now, no Roku remotes seem to work for me, and it appears the Pro remote is going back.
