Realtek High Definition Audio Driver Enhancements don't always work!

Recently I played Serious Sam Fusion 2017 both first and third person shooter 3D video games and then I noticed that all the enhancements of Realtek High Definition Audio Driver stopped working both entirely and completely including all the Environment, Voice Cancellation, Pitch Shift, Equalizer, Virtual Surround and Loudness Equalization!

It was exactly like all the enhancements of Realtek High Definition Audio Driver were all both completely and entirely disabled, but the truth is that they are all totally enabled and they are not disabled at all!

I know that this is the truth, because while I am in windows desktop I do hear these enhancements of Realtek High Definition Audio Driver when I hear any sounds of windows desktop and also when I play Serious Sam: Classics Revolution, Serious Sam 4 also both first and third person shooter and even Overwatch games!

I also hear all the enhancements of Realtek High Definition Audio Driver when I play The Neverhood game with the nhc.exe binary file and when I play any dos game and application with DOSBox-X emulator, but not when I play The Neverhood game with the ScummVM game player!

So finally I can conclude that sometimes the enhancements of Realtek High Definition Audio Driver work and sometimes they don't work at all or to be exact with some games and applications the enhancements of Realtek High Definition Audio Driver work and with some other games and applications the enhancements of Realtek High Definition Audio Driver don't work at all.

In summary: The enhancements of Realtek High Definition Audio Driver don't always working, but only sometimes yes with only some games and applications and sometimes not at all with some other games and applications and I don't know why this is so!

And also I don't remember that I ever encountered this very annoying issue in the past before I upgraded to Windows 10 Enterprise version 2004!

I want that the enhancements of Realtek High Definition Audio Driver to always work with all games and applications!

What should I do now to achieve this goal and purpose?
Please both help, assist and support me to solve this both issue and problem once and for all!
