Go to Preferences, Game Sounds, click on the Advance button, select music from popup and set the volume slider.
I must be especially dense as I see no "Preferences" on the Main Menu and the arena menus don't have the opening music option. What am I missing?Thanksiwlf
I've got an older system by today's standards that still runs the game well by my standards.
It's inside the game. Clipboard>Options>Preferences>Game Sounds>Advanced>Music
OK, start with Offline Practice, then follow as I said before.
