OK, I've been doing a lot more research -- here's what I've found. First, ARC supports, at best, compressed 5.1 format -- no Atmos, TrueHD, Neural etc. (https://www.cnet.com/news/what-is-au...n-channel-arc/
) Some TVs are said to support only stereo through ARC but, thank goodness, the 900 supports DD 5.1 and DTS 5.1 (https://www.rtings.com/tv/tests/inpu...io-passthrough
Also, while not relevant to the 900e/900f, there is a new ARC kid on the block called eARC which DOES support all the best sound formats (https://www.digitaltrends.com/home-t...ed-works-care/
). However, the first and apparently only Sony TVs to support this thus far are the A9F and Z9F (https://www.flatpanelshd.com/news.php
This means a total headache for me though. It turns out that there is a crazy patchwork of support (or lack of support) for the various combinations of 4K, HDR, and high bitrate audio for the 1) TV apps, 2) Xbox One S and 2) PS4. For instance, the PS4 supports high bitrate audio but not 4K (only the PS4 Pro does 4K). And while the TV apps will support 4K and HDR, it's clear now that they will NOT support high bitrate audio. And then there are per-app limitations, each app has its own patchwork of support on different devices. The Xbox One S will at least support 4K and high bitrate audio for my apps, Netflix and Amazon, but I'm still figuring out whether HDR is supported on that platform. What a headache!!
Edit: Netflix supports 4K and HDR on Xbox One S (https://help.netflix.com/en/node/42384
). And I already know that the Xbox supports high bitrate audio. Guess that'll be my preferred platform for Netflix going forward. (Meburdick -- yes, I have my external devices such as the Xbox all going into the AVR, a Denon X3300W, and from there a single HDMI to the TV. Thanks for the Apple TV idea, the Fire seems to support everything too, but I'm still in the process of verifying whether the Xbox supports everything I need... fingers crossed!)
Edit 2: I'm screwed. Amazon Prime does not support HDR except on a limited number of devices, and Xbox and even Apple TV are not on the list (https://www.amazon.com/gp/help/customer/display.html
). However, the Sony "Triluminos" TVs are on the list (and the x900 is Triluminos!!!) The answer MIGHT be the Roku player, which is on the list, but I'd have to cross-verify that it checks all the Netflix boxes too. So for Amazon Prime, with what I have now, I have a choice of a) using the TV Prime app and get HDR but only compressed 5.1; or b) use the Xbox, get uncompressed high bitrate audio for relevant titles BUT lose HDR. I think that for now I'll have to take the easy way out and just use the TV apps as I'll get the best available picture and will still get at least compressed 5.1 sound which isn't the end of the world. I guess that, at least for Netflix, I can use the Xbox if there's an Atmos or other high bitrate soundtrack available. I do have an Atmos setup 5.2.2.
