Audio from videos containing Dolby Audio cannot be played within Movies & TV APP.

Audio from videos containing Dolby Audio cannot be played within Movies & TV APP.

My Dolby Access is purchased and activated, and there are no issues with the sound card driver.

My system is running on Windows 10 LTSC edition, and while both Dolby Vision and Dolby Atmos are activated within Dolby Access, I find that Windows Movies & TV fails to decode all Dolby formats including Dolby Atmos audio tracks, resulting in no sound output, even though the color reproduction of Dolby Vision is accurate. Strangely, within the same Movies & TV application, DTS-HD and DTS:X audio tracks play without any issues.

Even more puzzling, the open-source VLC player is capable of properly activating and utilizing Dolby Atmos audio tracks and displaying compatibility with Dolby Atmos for Headphones.

What should I do?
