Quake 2 Vanilla - Regulating CD Music via Console

Hey Everybody,

I’m playing the original 1997 vanilla PC version of Quake 2 and everything works perfectly. But the music is way to loud and drowns out the sound effects. I saw that there is a command line that I can put in the console to regulate the volume of the music. However when I tried it it didn’t work. But maybe thats my fault for putting a spacebar to many or the command wasn’t written correctly in the first place. Thats why I wanted to ask: could somebody write down the exact way of useing that command for regulating the music volume and show me how to regulate its numbers correctly (i.e. 0.4, 0.5 etc).
