Ok. On my TCL TV, Roku OS 10 broke CEC volume control. It finally fixed it in Roku OS 12 after 2 years. And now, 12.5 (build 4175) just broke it again! And now it seems like it’s not just volume - no control via CEC whatsoever (eg receiver doesn’t power and volume control doesn’t work). Guys, this is ludicrous. Find out what you are doing in the code base and test it out. I’m soon going to be done with Roku OS. I’ve waited years for you guys to fix bugs and now you just reintroduced it.
