USB audio on Xbox Series X/S

There are multiple articles stating audio compatibility via USB. If optical is necessary, there are various HDMI to optical devices available which you may need to add.

"Some gaming headsets that utilize an optical cable may require a firmware update to support game and chat audio over USB on Xbox Series X. Soundbars and headsets that do not receive updates may be connected
directly to your televisions optical port."

Hi,

Series X|S optimised games can only run on either the internal storage or expansion card. You can 'store' Series X|S on a USB hard drive/SSD for later but you can't play them from these drives as they're not fast enough.

Xbox One games that are not optimised for Series X|S can be run from USB Storage.

Series S/X games cannot be played from a hard drive connected via USB. Series S/X games can only be played from the internal drive or the official expansion cards that attach directly in the back of the console. Again, no USB connected drives can play Series S/X games.

I have almost the same problem except the error message says

“if you’re using Xbox series X/S, note that HDMI audio can’t be turned off. In other consoles, either optical or HDMI audio must be on. (0x80bd0009)

Why can’t I turn off hdmi audio on Xbox series x it makes no sense?

the xbox one s and the xbox one x need an adapter to make it usb and that also comes with its own power supply.

the xbox series s and x don't support kinect.
