Bug: Some sounds in my sourcemod don't play

[ddddpplo]

Describe the bug

Lots of default sounds from Portal 2 don't play in my P2CE sourcemod, such as door sounds, portal gun sounds, cube dropper sounds, music, and dialog. All of my custom sounds work fine. (EDIT: Not all custom sounds work fine. I created a custom scene file and it's having the exact same issue. I even created the proper soundscript it needed, which makes me think this issue is related to soundscripts not loading correctly or something. I even looked at it closer and every sound that isn't playing correctly is inside a soundscript. Also, I should probably mention that ALL sounds work in hammer.) I haven't heard of other people having this issue so it could be something that I did wrong but I decided to open a github issue about it anyway.
