Here is a Dolby Audio Tester.
Some questions:
1. With Microsoft Edge using Chromium, will Dolby audio still be supported in the browser
2. Amazon Fire HD tablet supports Dolby audio in Silk Browser, https://www.amazon.com/dp/B07TMJ1R3X?ref=ods_ucc_tab_ony_nrc_ucc&th=1
3. Cordova support was audio in 2014, https://github.com/DolbyDev/Dolby-Audio-Plugin-for-Cordova, does it still work
4. Android support library uses Eclipse, will this be updated to use Gradle for dependency? Seems to vary by manufacturer. Is hardware required to support Dolby Audio and Atmos?
