Ok... wow after a few frustrating hours I have it.

First. Im running

Q80R tv

Q90R soundbar

Xbox one X

Connected.

Xbox hdmi out into soundbar hdmi 1

Soundbar hdmi arc to tv hdmi arc

Settings

Soundbar set to hdmi 1

Xbox - video settings

- most video mode check boxes on

- res = 4k

- fidelity and overides are default

- pretty much all green ticks in 4k tv details

Xbox - audio settings

- hdmi audio = bitstream out

- bitsream format = Dolby atmos

Tv

- source = soundbar

* note that in sound settings, expert settings the output says PCM but no need to pay attention since the source is the Xbox, nothing going from tv. If u flick to to a tv app like Netflix running on tv then it will change to atmos and send atmos to the
soundbar from tv.

Things I got wrong

- firmware latest on soundbar. I read a few posts about pass through not working on old firmware.

- the hdmi cable I was using for arc wasnt v1.4 cable. Seems that makes a difference... i had a v1.3 and nothing. A v1.4 comes with the q90r soundbar, use it for the arc connection.

Finally... how do I know it works.... I downloaded atmos test .mp4 from the Dolby website onto usb played on Xbox. No doubt... very happy

I have exactly the same problem. I have found that I can not connect the soundbar to the tv and xbox 1x via hdmi arc as this gives me the same error messages as yours. I have to connect Xbox 1X to hdmi inputs on the tv and use optical cable connection and
I then get all green ticks in the Xbox 1 Display settings.

I can get all my other devices to work fine via arc and get Atmos on Netflix tv app and dts audio but only get Dolby Digital when connected by Optical cable.

It is very frustrating as I can not get Atmos audio either on Xbox 1X.

Thanks for the response, I was up late trying to get it to work so I plan on directly connecting to the TV this evening after work to make sure of that. I'm hoping that I'm not stuck with having to connect to TV because then that means I'm losing out on
the Dolby ATMOS so cross my fingers its something I'm overlooking. It's frustrating that this isn't automatically detected and that clear instructions are not provided.

The sound bar is probably unable to process 4K. Check the manufacture specs to see if this is the issue.

Try direct connecting the Xbox to the TV and re-running the test.
