Sound does not work in some browsers.
Maybe all ... 😥
the game has sound in Editor Unity and Windows Mode.
I saw the old topics and their final result was a bug in the Unity version. I tried Unity 2021 and 2019LTS but it didn't work. The testing killed me one week. 2020v is base of project.
I also tried to limit and optimize the sounds of the game. It didn't work again.
If you have experience in solving the problem, please help me.
Update...
I created a game to test <<the ball>> with one audio source and one audio listener.
It worked, the sound worked clearly, I realized that the problem is that the web version is very limited.
It is impossible to create more than one audio source, which is impossible for a full 3D game.
