    Xbox Series X audio delay through eARC


    I've tried this with LG OLED C2 and Samsung S95B. No issues with PS5 and Apple TV, but Xbox Series X (and Switch) have noticeable audio delay/lag. I've tried all different combination of settings on TV and Xbox, but no success. Many other people have the same issue and have posted about it online, but there is no solution. This is really pushing me away from Xbox. Please help, thanks.

    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?

    Another XSX Dolby Atmos sound delay post. . .

    After a lot of test, to solve it i plug xbox on my lg cx with option sync AV arc bypass and activate earc with my denon 1600h.

    If earc is off there is a big audio delay but my denon receive an atmos emulated (pcm) for all game, If earc on no delay atmos OK on halo, forza etc... But no atmos on ubisoft game same as farcry 6.

    Ubisoft game not really atmos but a dolby 7.1 sound ?

    My conclusion If xbox use dolby atmos emulation or no earc there is a delay, if earc activate no delay but only atmos with game compatible

    Dolby Atmos delay on Xbox Series X

    Updated:

    I found that my soundbar SONY HT Z9F soundbar use HDMI 2.0 of which bandwidth is 18gbs connect to my TV using eARC port, so I changes my HDMI to

    8K HDMI of which soundbar is 48gbs, and the delay improve a lot that it is hard to notice now.

    ----------------------------------------------------------------------------------------------------------------------------------------------------------------------

    I have tested. My set is

    TV has enable eARC and set sound passthrough, HDMI BITSTREAM. XBOX SERIES allows PASSTHROUGH.

    XBOX SERIES X --> LG 65 QNED90 --> SONY HT Z9F (eARC)

    there is very noticeable delay on Atmos but don't have delay on any uncompressed sound like 5.1 or 7.1

    XBOX SERIES X --> SONY HT Z9F (eARC) --> LG 65 QNED90

    the atoms sound is sync with image, but I got a ton of delay on controller input, so I set TV image mode to Game Optimize,

    and set game mode to FPS, the controller input delay is gone, but now, i got atoms delay back...

    By the way, because my TV doesn't support DTS - X PASSTHROUGH, so when I connect XBOX to my soundbar, I could enable DTS X, and DTS X is working perfectly and there is no any delay comparing to Dolby Atmos.

    Razer Blade 15 with RTX 2070 MAX Q --> LG 65 QNED90 --> SONY HT Z9F (eARC)

    I don't have any input or atmos sound delay in this set.

    So here is conclusion:

    xbox series x has issue to passthrough Atmos content, even thought it is directly connect to sound bar, the sound or TV try to delay image to sync with atmos sound which causes a ton of input delay. But once you set the TV into low legacy input mode to get rid of input delay, the Atmos sound delay will be back.

    And Razer blade 15 with RTX 2070 MAX Q which is PC is perfectly working at Atmos without any issue.

    So this is definitely XBOX SERIES X ISSUE!!!!

    Another XSX Dolby Atmos sound delay post. . .

    I am experiencing the same issue. EARC, LG C1, auto is the only format in which the XSX will recognize Atmos capability, yet it introduces very significant delays. No delays in other formats. No atmos delays when streaming from my TV apps, only through the Xbox. Even in the menu, the audio “taps” come significantly after any action. This is extremely frustrating.

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

    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.
