Series X Dolby Atmos not working on Phillips OLED 708/12 Google TV

It's definitely not an AV issue. If you take a minute to type the issue into google search drive you'll find all different dolby atmos setups with different sound systems and Tv's that are very capable of providing dolby atmos and you'll find they all have the same issue with no solution.

I have the latest LG G1 OLED with the latest SP11RA dolby atmos soundbar with the same issue. the games are unplayable in Dolby atmos due to the delay. I have it changed to 7.1 for gaming, but I purchased the system to play dolby atmos gaming.

I have had the same issue with Netflix and Apple TV (a few months), no Dolby Atmos, although there is a label Dolby Atmos at the title and chosen track with Dolby Atmos in the application. My AVR shows a PCM input signal for this application.

My setup is: Xbox Series X - Denon AVR X3700H - TV Samsung 75Q80T

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,

Thank you for replying.

LG 65 inch OLED C9.

Soundbar Samsung HW 950. Both support Dolby Atmos.

Currently, the console is plugged into the TV via HDMI. Then the soundbar receives the sound via eARC.

Apple TV is configured the same way. Dolby Atmos works fine.

TV configured at 60 HZ, 30 bits per pixel.

I am not part of the Insiders Program, would it be worth enrolling?

4K HDMI cable, the same type of cable to Apple TV. Dolby Atmos works just fine.

Cheers.

I'm having the same issue. The program page says Atmos but my receiver is only getting a Dolby Surround signal (not DD+ which would indicate Atmos).

Not sure if its connected, but the Apple TV+ app on the Series X has also stopped outputting Atmos the last few months. So maybe its a more general Series X Atmos bug. Still works fine on Prime and Disney +.
