Xbox series x audio delay with Dolby

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.

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.

Audio delay on Xbox Series X



Question: Some games or movies on the Xbox Series X have audio/video sync issues, how can we fix this?



Answer: Dolby is currently investigating any A/V sync related issues while playing some games or watching some movies on the Xbox Series X with Dolby Atmos enabled. A/V latency problems normally occur because of specific hardware compatibility issues, faulty hardware, or incorrect configuration on one or more devices. For the Xbox Series X, users should double-check the below checklist to make sure your setup fully supports Dolby Atmos.



1. Are you connected to your TV or AVR using eARC?

2. Are you using HDMI 2.1 supported cables?

3. Does your AVR/soundbar support HDMI 2.1?

4. Is your TV configured correctly to use eARC?

5. Is Atmos enabled correctly on your Xbox Series X?



Additionally, one setting in the Xbox Series X that is known to cause some A/V sync errors is the feature to play content in 4k 120hz. This setting has been shown to cause audio delays with some hardware when playing Dolby Atmos content. Microsoft is currently looking into this issue. For a temporary solution, users should change the setting to 60hz.



Please see any of the above items apply to your system and fix as necessary. If you believe all is in correct order, please contact Dolby support to follow up with more troubleshooting.

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
