Lip Sync issue on Dolby Atmos with Xbox One X and Samsung HW-Q90R soundbar over HDMI ARC

Hi there Suisso,

Thanks for reaching out here in Xbox Forums. I understand there are some inquiries about Dolby Atmos on Xbox One S. I recommend to check out the following articles for more information about sound settings on Xbox One:

• Connect your Xbox One console to a sound system
• Windows Sonic and Dolby Atmos options and help on Xbox One

If the issues persists, I recommend to try contacting
Dolby Atmos Customer support
for more assistance.

Give this a try and let us know the results.

Hello

Thanks for your help but it didn't help.

So used the contact form from Dolby Atmos customer support, hopefully they'll be able to help or at least confirm if it's an ARC / eARC issue.

Thank you

Ok... wow after a few frustrating hours I have it.

First. Im running

Q80R tv

Q90R soundbar

Xbox one X

Connected.

Xbox hdmi out into soundbar hdmi 1

Soundbar hdmi arc to tv hdmi arc

Settings

Soundbar set to hdmi 1

Xbox - video settings

- most video mode check boxes on

- res = 4k

- fidelity and overides are default

- pretty much all green ticks in 4k tv details

Xbox - audio settings

- hdmi audio = bitstream out

- bitsream format = Dolby atmos

Tv

- source = soundbar

* note that in sound settings, expert settings the output says PCM but no need to pay attention since the source is the Xbox, nothing going from tv. If u flick to to a tv app like Netflix running on tv then it will change to atmos and send atmos to the
soundbar from tv.

Things I got wrong

- firmware latest on soundbar. I read a few posts about pass through not working on old firmware.

- the hdmi cable I was using for arc wasnt v1.4 cable. Seems that makes a difference... i had a v1.3 and nothing. A v1.4 comes with the q90r soundbar, use it for the arc connection.

Finally... how do I know it works.... I downloaded atmos test .mp4 from the Dolby website onto usb played on Xbox. No doubt... very happy

App is not recognizing my HDMI input from Samsung One Connect to the XBox One X and Samsung Q80R Soundbar. Called Samsung support...walked me through settings for television to ensure One Connect set properly and the Dolby App will not let me select ATMOS...just
DTS and Dolby.

Soundbar also would not update firmware when I inserted USB drive....so Samsung is asking me to send soundbar to them for repair/replacement. What a pain...

All I get is TV ARC on display....even if playing the ATMOS media from Dolby App on Xbox or YouTube Demo media.

I swapped out the HDMI between One Connect and XBOX with no change even rebooting system. Did rest on soundbar. Used regular, ethernet enabled and High Speed HDMI....got a couple 4k cables as well to try as last resort before I ship to Samsung for service.

So the journey begins.

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.
