Don't seem to be getting surround sound using Atmos soundbar on my Xbox X

I would look on the Samsung and Dolby websites to check the compatibility of the Sound bar. Sometimes the manufacturers have more information on what is compatible and where.

Hello dear Gamer, first it's a pleasure to be able to help you today.

My name is Vinicius.

I am a gamer and independent advisor on the XBOX community platform.

Hey Gabito787elmax, how are you today? Hope you're well.

Iportante Note: The Xbox Series X|S console does not have an HDMI in port. You won’t be able to connect your cable or satellite receiver to the console. Instead, connect your cable or satellite directly to your TV.

Because the Series X removed the optical output that previous Xbox models had.

If you have an HDMI ARC-enabled soundbar and TV:

1. Connect your console to the soundbar using the console’s HDMI output and one of the soundbar’s HDMI inputs.

2. With a second HDMI cable, connect the soundbar to the TV using ARC-enabled ports on both.

If you don't have ARC-enabled soundbar, but do have optical ports on your soundbar and TV:

1. Connect the Series X directly to your TV’s HDMI input.

2. Connect the TV to the soundbar using an optical cable.

Setting up surround sound will vary depending on your connection method and whether you’re using a soundbar system that's compatible with Dolby Atmos, 5.1 or 7.1 surround sound. Keep in mind that Atmos won’t work over optical connections, so you’ll need ARC or eARC for it.

If you don’t have an Atmos-ready soundbar, start by opening the console’s system settings. Open General, then Volume & audio output. You’ll have a few different options to choose:

If you’re using a soundbar with no digital surround sound functionality, choose Stereo Uncompressed.

If you can use surround sound and are using an HDMI ARC or eARC connection, select either 5.1 Uncompressed or 7.1 Uncompressed.

If you can use surround sound and are using an optical connection, choose Bitstream Out. Then, select either DTS Digital Surround or Dolby Digital as the bitstream format.

Enabling Dolby Atmos will first require you to download the Dolby Access app from the Microsoft Store. Ignore any offers to buy a license once you open it, as this is only necessary for certain Atmos-enabled headphones, rather than sound systems.

Once the app is installed, head to that Volume & audio output menu. Under Speaker audio, select Bitstream out, then choose Dolby Atmos for Home Theater as the bitstream format. Dolby Atmos will now be usable with movies and games.

I have the same problem with My xbox one x and 950 soundbar. I get audio delay once I enable Dolby atmos via the audio settings on my hdmi, but the soundbar works great with all other devices, cable TV, apple TV 4k. I've literally tried everything and
I'm thinking is has something to do with the Dolby atmos application. I've used optical and other sources and they sound good, obviously not Dolby atmos but they work. I don't think it's my TV or soundbar. I've also replaced the xbox one x to a new xbox one
x and same issue. It has to be a bug in the atmos connection from the speakers to the xbox. It's super frustrating. Not sure what else to do until I new update comes out.

I have the same problem outputting to Onkyo LS7200 Atmos soundbar, info on player shows Dolby HD even though disc is on Atmos soundtrack. Also I think the Atmos in game has echo on the surround channels which clears up if I go to DTS output from the sound
options on the xbox x . Overall not impressed.

Thanks for your reply. I understand the PS4 does not support 4k, but my Fire TV cube does. I plug my Fire TV into the HDMI in on the soundbar, and it plays in 4k and the soundbar recognizes Atmos. My tv is a Sony Bravia about 3 years old, so it does not have HDMI 2.1. I searched my owners manual, the settings on the tv, and the internet and could not find anywhere what version of HDMI my tv supports. I assume it is 2.0.

I am using the HDMI cable that came with the soundbar, no way to tell which version it is.

What I don't understand is why would my Fire TV pass through the soundbar correctly and provide Atmos sound? And also, why did my Series X work for a short time, and now won't? I was able to watch several UHD Blu-ray discs on the series x and was able to get Atmos. Then a few days ago, the XBox will not pass through the soundbar. I had to plug it back into the tv directly where I cannot get Atmos sound.

Another confusing thing is I plugged the soundbar into a different HDMI input on my tv, not the HDMI arc port (I don't have eARC, just ARC) and the XBox was able to pass through the soundbar correctly. However, this messed up my cable box sound since the soundbar was no longer connected via ARC. I used a digital optical cable for the cable box but had sound sync issues. Could it be some conflict with the HDMI arc input on my tv and the XBox? If that was the case, why did it work for a short time?
