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.

Hi Ehsaan,

Thanks for reaching out to the forums! We are sorry to hear about your issue and would like to help out. I have done some research on the soundbar in question LG SL6Y: 3.1 Channel Sound Bar w/DTS Virtual X & High Resolution Audio | LG USA and it appears that the soundbar does not support DTS:X or Dolby Atmos due to it not supporting 5.1 or 7.1 surround sound but is does support DTS: Virtual:X which the Series X does not.

With this particular soundbar your only audio option will be stereo uncompressed. I am linking the Xbox Support page concerning console audio settings so that you may see what your audio options are for your Series X console. Choosing speaker audio settings on your Xbox console | Xbox Support

For reference, HDMI ARC is meant for a TV to send the sound it receives from something like its digital TV tuner "upstream" to your soundbar.

The way you have it set up physically is correct, just that its not depending on ARC (Xbox One audio gets stripped from the HDMI cable by your soundbar and sends the video onto your TV).

Try changing the audio setting on the Xbox One to Stereo Uncompressed, make sure the soundbar isn't muted, etc. Maybe your Soundbar doesn't support 5.1 uncompressed, but 5.1 compressed Dolby Digital or DTS.

I'm using XSX & Jbl Bar 9.1.

Dolby Atmos gaming have Lag definitely compare with DTS, Lpcm 5.1&7.1.

So I don't use Dolby Atmos with XSX despite of my SYSTEM.
