As far as I've noticed, this is not an uncommon problem for this game but I seem to not be able to fix it. Sound works fine on my computer and, to my knowledge, the needed libraries are installed.

Could someone help me there? Please? Thank you! :)

Okay, I need good, strong coffee... I posted this here before checking on Linux Mint forums; I just did it and found the answer to my problems.

Here is the post that contains the solution: https://forums.linuxmint.com/viewtopic.php?p=1776971#p1776971 and here is the command to use if you have this problem on an Ubuntu based Linux operating system:

sudo apt-get install libc6:i386 libasound2:i386 libasound2-data:i386 libasound2-plugins:i386 libstdc++6:i386 libx11-6:i386 libxau6:i386 libxcb1:i386 libxcursor1:i386 libxdmcp6:i386 libxext6:i386 libxfixes3:i386 libxinerama1:i386 libxrandr2:i386 libxrender1:i386 libglu1:i386

Okay, I'm really bad at this. The list is fully mentioned in the requirements on the store page... Sigh Shame on me... :P
