Xbox One X: Enhanced Audio Return Channel (eARC) support

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?

Thanks for the response. That’s along the lines of what I was thinking (the xbox not needing to support eARC). This would mean the current issue I am experiencing is caused by my TV not properly passing through the audio of the Xbox.

From what I’ve seen, the higher bandwidth of eARC is required to pass through full, uncompressed Dolby Atmos with no A/V sync issues. I am currently having an issue where the audio from the Xbox is lagging behind the video whenever I play a game with Dolby
Atmos enabled. Ex: I fire a shot in Call of Duty and the sound has a delay. Just wondering if its my TV having a software issue or if its the Xbox.

My current console setup is:

Xbox plugged directly into my TV (2019 LG C9 OLED, which supports eARC and Dolby Atmos). All of the ports on the TV support HDMI 2.1 features (eARC, ALLM, VRR/FreeSync, etc...)

I have my sound bar (Sony Z9F, which also supports eARC and Dolby Atmos) plugged directly into the TV.

The Xbox and sound bar are both connected to the TV via Ultra High Speed HDMI cables that support eARC.

Yes I looked through the support page. Unfortunately, I was unable to find an answer to my question.

Just received a response from LG. Looks like the audio delay issue is definitely an issue with the TV and NOT the Xbox One X.

Thanks for all your responses anyways. Appreciate the help figuring this out. Have a good one!
