Ошибка, которую я получаю при первой загрузке приложения.Когда я очищаю ошибку в devtools, ошибка не возвращается, и я вижу эти два журнала, но не слышу никаких звуков. 

    console.log('current item', this.currentItem);
    console.log('clicked from onclickplaylist');

Ошибка состоит в том, чтобы долго публиковать здесь.Вы можете видеть это на проблеме github, которую я также отправил.https://github.com/videogular/videogular2/issues/786

Это мой рабочий код:

audioplayer.ts 

import { Component, OnInit } from '@angular/core';
import { VgAPI } from 'videogular2/core';
export interface IMedia {
  title: string;
  src: string;
  type: string;
}
@Component({
  selector: 'app-audio-player',
  templateUrl: './audio-player.component.html',
  styleUrls: ['./audio-player.component.css']
})
export class AudioPlayerComponent implements OnInit {
  playlist: Array <IMedia> = [
   {
      title: 'Bell',
      src: './assets/audio/bell-3.wav',
      type: 'audio/wav'
    },
    {
      title: 'compact car',
      src: './assets/audio/compact-car-screeching.wav',
      type: 'audio/wav'
    }
  ];

  currentIndex = 0;
  currentItem: IMedia = this.playlist[ this.currentIndex ];
  api: VgAPI;
  public name: string;
  controls: boolean = false;
  autoplay: boolean = true;
  loop: boolean = false;
  preload: string = 'auto';

  constructor() { }


  onClickPLaylistItem(item: IMedia, index: number) {
    this.currentIndex = index;
    this.currentItem = item;
  }

  onPlayerReady(api: VgAPI) {
    this.api = api;

    this.api.getDefaultMedia().subscriptions.ended.subscribe(
        () => {
            // Set the video to the beginning
            this.api.getDefaultMedia().currentTime = 0;
        }
    );

}

  ngOnInit() {}
}

audioplayer.html 

<div class="buttons">
<button mat-raised-button (click)="onClickPLaylistItem(item, $index); api.play()" *ngFor="let item of playlist; let $index = index" >
    {{ item.title }}

  </button>
<vg-player (onPlayerReady)="onPlayerReady($event)">

  <vg-controls>
    <vg-play-pause></vg-play-pause>

  </vg-controls>
  <audio #media [vgMedia]="media" [src]="currentItem.src" id="modalPlayer" preload="none"></audio>
</vg-player>
