Xbox to Soundbar on monitor

if the monitor has a 3.5mm output and the soundbar has that as an input then that way. lg tv's these days have arc so could have attached soundbar to arc hdmi port and then xbox to another port on the tv, but as you have a monitor the options are limited.

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.

basically nope, you monitor wont have arc ability, and the xbox does not output sound via usb

Then how will i be able to connect my LG monitor to my LG soundbar in a way that it gets my xbox sound

I have an optical cable connected to my soundbar. I disable the TV speaker from my TV, so then the 360 just outputs to my soundbar. So if this is an available setting on your monitor, try it.
