Okay, let me try to be extra clear.
The game has several sound settings: ambience, sims voices, general sound effects, and the music.
Currently, the options to adjust the volumes of these various sounds individually does not work. The volume controls of Windows can only turn volume up or down for the entire application, not just the music. (That's my understanding anyway. ) The music currently plays at full volume and that's way too loud in my opinion and there's no way it can be adjusted. Using Windows Volume, every sound in the game would be muted and that's not what I'm trying to do.
