Audio not working for some weird reason

[AtilaSaraiva]

First of all, thank you for making this script. I've been trying to make the lutris script work, but to no avail. I'm really lucky to have found this repo.
Nevertheless, my game is without audio for some reason, and I don't know where to start to solve this problem. Do you know what could it be?

Edit: It seems like I had to install the following packages (on arch linux) for it to work:
lib32-alsa-plugins lib32-libpulse lib32-openal
sorry to trouble you with such a silly question. Nevertheless, I hope it will help somebody in the future.
