We suggest that you check if its being detected by following these steps:

  sound icon.
• Right click on the sound icon, a smaill window will pop up with the Sound
  menus.
• Click on the Playback Devices.
• The Sound window will appear with the Playback
  tab.
• Look for Dolby Atmos to make sure that it is properly installed.

If its not on the list in Playback Devices, kindly check if its listed in Device Manager by:

• From the Start menu, type in Device Manager, then
  Enter.
• Then click the Sound, video and game controllers driver.
• Look for Dolby Atmos, then right click on it, then click
  Unintall.

Dolby Atmos

I checked this line:

5. Look for Dolby Atmos to make sure that it is properly installed.

and i have list with my two audio cards :

1. onboard - Realtek High Definition audio

and

2. dedicated Asus xonar DG audio device.

When selecting option 1. i have spatial sound dolby atmos option, but when selecting option 2, i have listed only "none" under spatial sound.

I can confirm that i had spatial sound on previous win10 build

For this part:

• From the Start menu, type in Device Manager, then Enter.
• Then click the Sound, video and game controllers driver.
• Look for Dolby Atmos, then right click on it, then click Unintall.
• Once done, remove your Dolby Atmos device and restart you computer.

Dolby Atmos won't install

I have downloaded the Dolby Access app through Windows Store, I have gone through the "getting Dolby Atmos" prompts through the app, I opted to go with the 30 day trial and it appeared to be installing Dolby while a loading spinner ran over the trial option.
Afterwards it prompted me to begin setup of Dolby Atmos by going to my device properties -> Spatial Sound -> Dolby Atmos...however the option "Dolby Atmos" is not there.

I figured maybe I just need to restart my computer to finish the install but even after restarting I still only see the option "off" under the Spatial Sound tab. There does not seem to be anyway to attempt to re-install the software as there is no program
listed for Dolby Atmos in my Programs list and the Dolby Access app seems to believe it is installed on my computer.

How can I go about fixing this issue?
