Why the SoundMix Volume Change has a little delay?

[EGO.I]

I use a slider to change SoundMix Volume. In picture, the “OnValueChange” actually is Slider’s “On Mouse Capture End”.
When I change the slider value, there is a small delay in the change of sound. For example, when the volume is adjusted from 100 to 0, the sound gradually becomes smaller.
How can i fix this delay?

Set Fade in Time to 0 on the Set Sound Mix Modifier, that will make audio change instantly

Please tell me if it helped or if you need more help
