Oh, actualy, in my case my music is an audio component inside my game mode, and my main menu uses a child bp of the game mode. From there I can get the music component and set its UI Sound to true and this works. Now it’s specific to my menu music only.
I thought this would affect the volume control of my audio cue as I want it to be set to music so I can adjust the music volume in my settings. I am pleased to say that setting the audio component to UI Sound does not affect the SoundClass, so it still responds to my music volume setting.
