DANG!!! Sorry about that... I have no way to test the Linux version myself, compiled it for a friend, who didn't mention lack of sound. I'll see what I can do
I recommend to you try virtualbox. It is very easy. You can install here any linux distribution (I recommend manjaro, ubuntu can be good option too but it consumes more resources).
I posted the final version recently... hopefully you can get a chance to try it out. Thanks again for making such great tunes for people to use!! My next game is in the works, so I will be dipping into your spookier tunes this time.
