Some mods wouldn't have any sounds for me, when they seemed to work fine for others.

I believe this mainly affects users running off some form of Fedora, I'm running off Bazzite myself, but when installing mods from the workshop I noticed that some mods wouldn't play their sounds. Looking into this, I thought maybe something was up with the mod, did some digging, noticed it used mp3 files when the core game seems to use wav, but that was a dead end.

In the end after a bit of digging I came across this[github.com].

Following the advice from the above, I confirmed through logs that my device was blocking it because of the mentioned security vulnerability in the Source sound system.

After doing the above my sound worked without issue, so I thought I'd make this guide as figuring out the above and finding it was a bit tedious.
