@heyitsrick thank you for these testing suggestions, problem SOLVED. Although these tests (power cycle, different hdmi input, etc) had no impact, the process of testing helped my find the “enhanced 4K hdmi” input setting was off on the Sony TV for the hdmi inputs used with the AVR. Resetting these to “on” rebooted Android, and audio/video was restored through the AVR.
Apologies for new thread, and obvious frustration. No solution and radio silence to the original post wasn’t helping. I appreciate the Community, and I’m grateful how starting a new strand led to you. I will edit my original post to reduce snark.
This is the second time since purchasing the Ultra that it was rendered non-functional after a system update. Last year when it was fairly new, I returned it for a new one to no avail. It turned out to be a D+ problem, uncovered in the Community. In all, I’ve had about 3 weeks of non functionality and hours of testing and community time over a year of ownership to keep it working. I honestly can’t recommend Roku to friends and family. In my experience, Roku has proven to be unreliable and without adequate support. I still have a support case number, with no response.
Best wishes to fellow users.
