After upgrading to driver version 184.108.40.20658 my PC lost support for Dolby Atmos. Tried to reinstall Atmos driver but didn't help. Had to revert back to 220.127.116.1163 to get Dolby Atmos working again.
Thank you for posting on the Intel ® communities.
When you updated the driver, did you download it from Intel's site or was it provided by the manufacturer of your system? If from Intel, please try to install the latest one validated by your system manufacturer, this is important because We supply generic versions of graphics drivers for general purposes. Computer manufacturers can change the features, incorporate customization, or make other changes to the graphics driver software or software packaging.
Also, to better assist you with your request, I will need to check some information about your computer. Please follow these steps:
1. In the keyboard, press WinLogo key + R.
2. In the Run box please type dxdiag and hit Enter.
3. Click on Save All Information (save it in your desktop).
4. Attach the report to this thread.
