No Sound w/ Dolby Atmos (Alpha Skip Ahead)

"xbox not being able to play dolby atmos"

According to the Latest Alpha skip ahead Insider release notes this is still an issue the engineers are tracking and working on.

Hello!! I'm in the alpha skip ahead. With the last build the problem is fixed. Now it's multichannel in the dashboard, when you load an atmos game the display will change in atmos. Same for netflix.

This is fantasic news! Thanks. So just to be clear it seems that Microsoft solved it? Or did Dolby Access get an alpha update?

Hi have you contacted support over this? My one x updated fine I've had the update for a month or two now with the alpha skip ahead release, and the only issue I seem to get is that the dolby atmos app sometimes needs redownloading for the system to recognise
it but then it works fine for weeks.

As far as my understanding this issue is related to the color bit-depth selected or perhaps the refresh rate when set to 120hz.

Personally, I'm using 1440p, 120hz, and 10-bit. I haven't had any major issues using Dolby Atmos with this setting.

Although, once or twice I've had to re-open the Dolby app to re-apply the settings.

Here is the current known issue and workaround. I hope this helps

"Audio

• Users who have Dolby Atmos enabled and console display settings set to 120hz with 36 bits per pixel (12-bit) are experiencing loss of Dolby Atmos audio in some situations.
  • Workaround: Disable 120hz or set Video Fidelity to 30 bits per pixel (10-bit) or lower."
