After re-installation of windows 10

I am even try re-installation two times

I am no longer see the Dolby atmos app and feel the speaker quality quite bad.

I am coming to razer support for my device ( balde 15 advanced 2018 ) but dolby atmos app is not in the support list ( meanwhile other model like base 2018 is available)

Is there any solution for me?

Thank for your help!
