Unity3D game has no sound

So I've been trying to get a Unity3D-made game (native linux build) to work properly on my Debian Sid 64-bit install, and it does work, however there's no sound.
I tried contacting the developers of that game, but they apologised and said that they don't have any way of testing the game on Debian (wtf? they're a game studio and they can't be arsed to make a VM with Debian? jeez...), and that the game has only been tested and is supported on Ubuntu. I then asked them to give me the resolution to this problem for Ubuntu, but they haven't replied since.

I've tried ldd'ing on the executable to see if I'm having any missing dependencies, but it doesn't list anything audio-related, only X11, rendering and OpenGL stuff:

Also I don't get any useful info in STDOUT when running the game from the terminal. Anyone know what I could do to troubleshoot this?
It could be that I'm using straight-up ALSA instead of PulseAudio, and perhaps Unity is strictly looking for the latter. If this is the case, do you guys have any idea how to force it to use ALSA? I've never had any issues with any app/game with PulseAudio missing.
