Audio volume is not work

when i use audio volume and sound cue, but audio volume do not work. I place sound cue into audio volume, whether i in the volume or not, i can hear the music, do i miss some setting?

Is the sound file a WAV?, It needs to be converted to WAV before you import it into Unreal. Also, try adding a modulator to the sound cue and adjust the volume from there

Can you put some screenshots,? thanks.

my setting is follow, do i miss some setting?
