I have some jquery code that calls a function called playSound, which plays a sound file when a dialog box opens. The sound file plays in firefox but not in IE11. It even plays in IE9. Does IE11 require some specific programming? I'm using jquery-1.8.3.min.js

1. function playSound(soundfile){
      $('#dummy').html("<audio autoplay='autoplay'><source src='" + soundfile + "wav' type='audio/wav' /><source src='" + soundfile + "mp3' type='audio/mp3' />Audio tag not supported.</audio>");
     }
   
   
2. playSound("media/alert.");
   $("#arrivalNotification").dialog("open");
   if(soundTimer){
        clearInterval(soundTimer);
   }
   soundTimer=setInterval(function() {playSound('media/alert.');}, chimeDelay);
