Hdmi e-arc audio Studio quality audio on Xbox series X

Hi Eat! My name is Ricardo an independent advisor ready to help you with this situation!

We can't say why it's not one like the one you mentioned on the Xbox but you can download the Dolby access app to configure the Dolby audio settings

As the Xbox One X is an audio source, it doesn't need to send or receive audio via ARC or eARC.

Audio Return Channel is only for TV's that are supposed to "return" Audio back to an AV receiver or connected Soundbar.

As the Xbox One X doesn't have speakers to play audio recieved through ARC, it won't support "ARC" or "eARC". Your TV needs to support ARC or eARC.

What exactly is your TV and console setup, that you would need eARC in the Xbox One X?

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?

It is connected via hdmi arc directly to the soundbar. arc is just the shortform for HDMI audio return channel.

Chech your tv for hdmi arc (audio return channel) and use that for audio out
