MinimumInterval=0 ?

1.Pictured above. How long does the sound play?

2.MinimumInterval=0

Pictured above.Means the sound playback time is: 0?
In other words: when the sound is playing, there is no sound. right?

But why does the program still make a sound when it is executed?

This has already been answered here:

It does not mean that. It means the time interval of "no sound" between sounds. So if I set that to 1 second and I had 4 sound files the sequence would be:

Sound File1 playing
Sound File1 ended
1 second interval
Sound File 2 playing
Sound File 2 ended
1 second interval
Sound File 3 playing
Sound File 3 ended
1 second interval
Sound File 4 playing
Sound File 4 ended
1 second interval
