Sony A8F Dolby Digital 5.1 output and passthrough

[coloradotrav]

Equipment:
* 2018 Sony A8F (https://www.sony.com/electronics/televisions/a8f-series)
* Sonos Beam in 5.1 setup (Sonos sub, 2 Sonos One as rear surround)
  * Connected via HDMI ARC on input 3 of the Sony TV
* Xbox One X

  * Connected via HDMI 2 input

Software:
* Android TV (7.x)
* Youtube on Android TV

* Xbox One X games

I have the equipment and software described above and I AM able to experience Dolby Digital 5.1 from Netflix on my Sony Android TV app, However I am only getting stereo input sent to the Sonos Beam from:
* The Sony Android TV youtube app when running every type of Dolby Digital surround test
* From the Xbox One X

I've tried sound set to Auto 1 and Auto 2 on the Sony, but this doesn't change things. On the Xbox, I have it set to output Dolby Digital 5.1.

I've looked through these forums and didn't get a quick answer. The biggest thing I've determined is that the Beam only supports PCM and 5.1 (not DD+, Atmos, DTS, DTS:X). Of course 5.1 is all it can support in this set up, but I can't seem to figure out how to force the Sony to passthrough 5.1 or to convert youtube content to 5.1. Can somebody please help?

Hi coloradotrav,

Having the TV stream content that's in 5.1 is one thing, and expecting it to pass-through signal in a specific format is something else entirely. I don't think since the TV supports one it means it supports the other.

In other words, this is possibly expected and I don't think it's a fault or something you can fix.
