You just can’t.
The ONLY way to do this (I have been doing it since my previous post here +2 years ago) is to build your own engine from sources.
When you are at the VS part:
-look for the “file” audio.h
-look for Pitch.
-change the value: From 0.4 to 0.001
ZERO will crash the build.
Build your engine.
Voila.
You just wasted an hour and a half just to change a value. Welcome to my club!
