title: howler "playback was unable to start"
body: <p>I'm creating an angular App (PWA) which need to play a list of audio file.
  I'm using Howler librairy</p>
  
  <p>First , I've found why it's didn't work on iOS, it's because the flag html5 of howler must be set to TRUE.</p>
  
  <p>Now, I've an other issue on iOS only ! (not in MAC, Android, Windows). I can't manage to launch an other audio file when the first is finished !</p>
  
  <p>Error msg : Playback was unable to start. This is most commonly an issue on mobile devices and Chrome where playback was not within a user interaction</p>
  
  <p>=> Please help me to avoid that !</p>
  
  <pre><code>var sound = new Howl({
    src: ['/assets/fr/audio/gsp.mp3'],
    format : ['mp3'],
    html5: true
  });
  
  
  
  sound.on('end', function(){
    alert('end out');
    var sound_suite = new Howl({
      src: ['/assets/fr/audio/gsp.mp3'],
      format : ['mp3'],
      html5: true,
    });
  
  
  
  
    sound_suite.on('playerror',function(id,error){
      alert('error OP: ' + error); //&lt;===== Error here : Playback was unable to start. This is most commonly an issue on mobile devices and Chrome where playback was not within a user interaction
    });
  
  
    sound_suite.play();
  </code></pre>
