Ionic Native Audio Delay (fade in/fade out) not working

Hello there,

I’m trying to make the fade in / fade out effect using the Native Audio Plugin and its does nothing. The music simply play without any delay.

I tested it on Browser and Android 7.1 . I have the following code:


loadmusic(path: string){
			this.nativeAudio.preloadComplex('audio', path, 1, 1, 5000).then(() => {'audio');
			this.loader = true;

(The ‘5000’ was for testing purposes, it doesn’t work with smallest numbers either)

Everything works but the delay feature. Anyone?
