Samsung Q700A Soundbar can't Passtrough Dolby Atmos audio on Xbox

I have a LG C1 TV and a Samsung Q700A Soundbar, both of them are new release in 2021.

The question is after I set all up, my Xbox just can't passthrough Dolby Atmos audio to my new Soundbar.

My setting>>> TV set to Passthrough with eARC enable, Xbox set to bitstream

When I set my Xbox to bitstream, I can't choose Dolby Atmos Home theater. It says my Soundbar doesn't support Dolby Atmos, which is not true.

I used Sony's HT-X8500 Soundbar before, and I didn't encounter problem like this.

How can I solve this problem?

 

Edit 1: Both of them are in the latest firmware version

Edit 2: I don't want to connect my Xbox Series X directly to Soundbar because I'll lose all of HDMI 2.1 benefits

Seems to be a TV issue from what I have read on other forums. What I did glean was you need to set the XBox to automatic. I would recommend looking at LG forums as this is where the issue lies.

I don't think this is LG's or other manufacturer's problem. This is an issue since last year's Samsung's Soundbar had.

You can search "Q950T", There were lots of similar thread discussed about eARC issue on Samsung's 2020/2021 Soundbar, which was told that thier Soundbar didn't support multi channel LPCM through eARC.

And now we have the same eARC issue in this year's product (Q700A, Q950A)

Thanks for your reply

There are lots of thread pointed out that Samsung's 2020/2021 Soundbars have some kind of eARC issue that needs to be fixed. 

Not just Xbox, it also happens on Apple TV 4K.

I used Sony's HTX8500 Soundbar before I purchased Samsung's Q700A. There is no issue on Xbox+LG C1+HTX8500 set up while outputting Dolby Atmos.

This is definitely Samsung's problem, and it has not been fixed since last year.
