I've put the TV first, last, and increased the delays on both, separately and together, in controlled increments, but I sure can't seem to find the right 'combination'. I've tried NUMEROUS combinations, the ones that made sense, or seemed to make the most sense, but all it does is produce literally inconsistent results, in terms of the TV staying on (instead of turning on-off), and in terms of the inputs. This whole 'how to transport the right audio signal if >DD' mess is just that, even if you're pretty technical, it's tricky to see who's compatible with what, because the manufacturers tend to not add a field at all, if it's not currently supported (on spec-sheets and such).ДЄll that aside, is there a method/algorithm for tweaking the start-order and power-on-delay(s)?

It's hard to guess which way this might go (I suspect this extends to a LOT more than my receiver).Д®ven so though, it should be able to support Atmos through the DD+ codec (possibly lossy, I suppose, but better than not having it at all), at least in theory. It seems like, since HDMI has had this support since 2.1, that this should/might be a firmware fix, but now they're selling the XX-XX5 series, such as the RX-A775, with eARC specifically called out.

Yeah, good point, on the eARC thing, I'm pretty sure it does not (Yamaha RX-A770) have this support, at least out of the box.
