Windows 10: April Patches Breaking Atmos?

Yesterday my PC was able to output dolby atmos to my home theater. Today, when I tried to switch to atmos after plugging in my PC->receiver's HDMI cable, it brought up a dolby app and requested a reboot to enable atmos. I've never seen this dolby app before. I believe it's a windows store app called "Dolby Access." I rebooted. Now everything but stereo fails to initialize. Was there something related to sound installed with this week's patch tuesday that could be causing this? (or pushed by other means). I don't think I've installed anything else (nvidia drivers, etc) in the last couple days that would have caused this. I'm on 1809. If there have been app/driver/windows updates made recently, identifying them would help me with troubleshooting.


Thanks,

Can't enable Dolby Atmos for headphones in spacial sound

Hi Aman,

This issue should be resolved by reinstalling the drivers on the built-in administrator on your computer. We suggest that you install the latest update for your Windows first. After you've done that, access the built-in administrator and reinstall the drivers
for Dolby Atmos. To access the hidden administrator, kindly follow these steps:

• Press Windows key + X, and select Command Prompt (Admin).
• Type net user administrator /active:yes. You should see a message that the command was successful.
• Restart your computer. You should see the Administrator account.

Note: The built-in administrator should be used for troubleshooting purposes only. Once you've reinstalled the drivers for Dolby Atmos, kindly follow these steps to disable the built-in administrator:

• Press Windows key + X, and select Command Prompt (Admin).
• Type net user administrator /active:no. You should see a message that the command was successful.
• Restart your computer. The administrator account should no longer appear after this.

Let us know how it goes and we'll assist you further if needed.
