Ok so is it possible to mute the music but still have the SFX? The music choice wasn’t the best in my opinion…
I have no looked but try pressing the menu button (old start button) and check what options are available under audio.
Of course you can turn off music and still hear the sound effects. There are even separate settings for race music and menu music. I have both off.
On the Forza home screen select My Profile then select the audio tab. You will see the options for in race music and menu music, just set those to off.
