Soundfont does not obey dynamics changes in any way

This is really starting to frustrate me. I'm using a soundfont called "Beepcomp" to try to make 8-bit sounding music. However, I have found that in Musescore 3.6.2, which I use, none of the sounds change volume at all according to dynamics markings (like p, f). This means that a note marked as fff has the same volume as one marked ppp. I've tried converting it to a .sf3 file, tried resetting things in the inspector, tried changing synthesizer settings, and have gotten nothing. I even tried using Musescore 4.2.1 but I guess soundfonts don't work at all there, they're just silent. Does anyone have an idea of how to fix this problem in either version of Musescore?
