Yamaha TSR-7810 and LG OLED don't play nicely together
I've written about this here before and got no responses, and have more data, so let me try again.
I'm having some real issues integrating my system so everything plays nicely together. I have the 65" LG E6 OLED TV, the Yamaha TSR-7810 A/V UHD receiver, an Amazon UHD Fire box, an HD TiVo Roamio and the Samsung K8500 UHD DVD player. Using HDMI2 (the ARC input) on the E6, fed from the ARC-enabled output of the Yamaha.
When I turn CEC on everywhere, the part of CEC that controls power to everything if you turn on/off anything works just fine, as does the part where any remote's buttons can control basic functions like volume, mute, play/pause, etc. Actually, all those things work very nicely.
Here's what doesn't work:
-With the E6 and Yamaha connected, both with CEC/ARC enabled, turning on the system causes a random input selection on the Yamaha receiver; sometimes it selects the DVD player, sometimes the Fire box, and sometimes it goes to the ARC input. It almost never selects the TiVo, which is the input where it was when shut down 99% of the time. It's maddening.
-If I turn off CEC/ARC, or disconnect the LG from the Yamaha, the Yamaha always comes up with the input that was selected when it was powered off, which is the way it should act all the time.
-With CEC/ARC enabled, going to the apps on the LG (I usually go to Amazon streaming), the LG tells the Yamaha correctly to switch to ARC mode, and audio comes from the Yamaha. But when I exit streaming mode on the LG, the Yamaha doesn't drop ARC mode and return to normal 99% of the time - it just stays on the ARC input, and of course I get no audio. And sometimes when that happens, the LG will modify its audio settings and turn on its internal speakers, which is something I never want.
Anyone have any experience with this? It's driving me bonkers. I'm back to what I hate, which is having four remotes to get anything done, having to switch everything manually. CEC/ARC was supposed to fix that issue, no? Please don't recommend I get a universal remote with 'activities'. I have a Logitech one, but my eyes have aged out of being able to use a remote with 250 tiny buttons and labels only a 20 year old can see in the dark without a flashlight and magnifying glass.
And really, I should be able to turn the system on and have it come up where I left it without having to manually select the Yamaha's input every single time.
I would really, really like to get CEC/ARC working the way it's supposed to, and of course both the Yamaha and LG manual have the disclaimer that it may only work correctly when all components are from the same manufacturer, which is just stupid for what is supposed to be a universal protocol agreed upon by all manufacturers.
Any help, suggestions, or sympathy appreciated. Also please tell me if I'm doing something stupid.
