I'm on Linux Mint 21.2, though I've tried installing this game on another Debian-based distro with the same results.

So, the game launches and everything seems to be perfectly in order, except there's no sound.

Files in the game folder are .wav and seem to work perfectly when I launch them with Audacious.

There is no information online, it seems like I'm the first person trying to launch this game on Linux.

Here's the log:

I tried posting this on Reddit and got no help. I was hoping here people might be more responsive.
