So today while trying to add a sound system to my game I realized that the volume thing in sounds

change volume by ()
set volume to () %

that neither of these worked no matter how I tried to change them. I set them to 0% and 0 volume I set it to 1000% and 1000 volume, nothing changed the volume played the same. Anyone know why?

First of all, nothing can go over 100% volume. I do not know the reason, though.
Edit: maybe a little unclear, I meant the reason for the problem oops

it doesnt change the volume at all like no matter what i set it

Did you test the sound with a block after you changed the volume?
