@Dodi - That site gets flagged as unsafe for me.
In the future I suggest using a reputable download source like Github (you can create a free account) or dropbox (again free).
Yeah, you can’t really do that. The sounds won’t sum. i.e. simultaneous sounds are not additive
The best you can do is defer the sound and play just one sound louder, but you’ll have to start at something below 1.0 to increase.

After playing hours with the roaminggamer’s code, I return to the topic and read well the comment of nick_sherman. I have added this function and the problem has been solved. Here I leave the code for those who want to try. Apparently the physical objects do not collide at the same time in any situation, there is always a small delay.
