Audio Delay - Xbox Series S + Dolby Atmos

Hello AnchelLabena,

We appreciate you for bringing this up to Xbox Forum.

We are sorry to hear that you’re experiencing audio delay when using Dolby Atmos for Home Cinema on your Xbox Series X with LG OLED C2 TV and Samsung Q950T Dolby Atmos soundbar.

We've found similar issues with LG OLED and LG Atmos soundbar (with rear speakers) and used an earc extractor (4k Dolby Atmos compatible) which completely solved the problem. You pass the audio HDMI earc out from the TV through the extractor and into the HDMI in of your sound bar.

Another user, states having delays using the Xbox Series X with Dolby Atmos games and apps such as Youtube and Gears 5 but NOT from the Dolby Atmos app’s demos. The Xbox is connected directly to their LG BX TV via the HDMI 2.1 and using eARC > ARC on their Onkyo TX-NR656. The TV’s apps do not cause this delay using Atmos, and the Dolby App on the Xbox.

We also found an explanation from another that the delay exists because natively, surround audio from a gaming console is in LPCM. To output a bit streaming format (or in this case a proprietary PCM codec like DOLBY MAT 2.0) it has to re-encode the audio real-time which introduces delay. And keep in mind ONLY a very select few games are in Atmos.

It's good to know that connecting the Series X directly to the soundbar works just fine and Atmos content will play as intended with no delay. However, this causes a loss in other features such as VRR, 120 Hz and more due to the soundbar not supporting all HDMI 2.1 features.

We understand that you want to do the setup with the console connected directly to the TV, as should be intended. We hope that the information we provided is helpful.

If you have any other questions or concerns, please let us know.

We will be glad to follow up and help you.

Sincerely,

Interesting post, thank you for trying and posting your findings.

I've had the audio delay issue for years and tried everything. I had the nu8000 Samsung TV before and recently got the qn90b and the issue is still present.

My set up is, Xbox series x > qn90b > onkyo 676.

If I do 5.1, stereo uncompressed, mono, there's no delay. There is only an audio delay with dolby atmos for home theatre option.

Your suggestion does not work on my end however, because the only way I can set the qn90b to pass-through is if I unselect the dolby atmos option under it, which allows me to change audio output format from auto or pcm, to pass-through but when I do that, the Xbox series x no longer detects my set up as dolby 5.1/7.1/atmls capable and says not supported so I can't even force the Xbox to output atmos.

As for the qn90b audio delay option, it's already at 0, and the delay is very noticeable in shooter games, but especially while watching movie.

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

Well yes. The problem is constant. Whenever you’re in a game that uses Dolby atmos or even on Netflix through the series x. It needs a software patch to fix it. Delay is present on all Dolby atmos content

I have same problem everything shows as dolby atmos. I just get on with it . I dont have audio delay though 🤔

There are issues with dolby atmos that has been on going for a while though. Still no fix 🤔👍
