This version has vorb orbiss sound, but there is still no ingame music. You have some music here and there, but there is a whole fear factory soundtrack that should be playing while playing the game. Does anyone know how to get this music working?

If I recall correctly, there were some issues with the soundtrack.

First of all, I know it might sound obvious to ask, but... is the soundtrack active in the game options? There is an option for that.
