My problem:

I use the Media Class from Cordova. The MP3 file is only played once (the first time).

Code:

Add this code to the Cordova Starter project to reproduce my problem:

    var playCounter = 0;
    function playMP3(){
      console.log("playMP3() counter " + playCounter);
      var my_media = new Media("app/www/test.mp3");//ressource buildAction == content
      my_media.play();
      playCounter++;
    }
    [...]
    <p onclick="playMP3();">Click to Play MP3</p>

VS output:

[...]

My Config:

• cordova-1.6.1.js
• Lumia 800
• WP 7.5 (7.10.7740.16)

WorkAround (kind of):

• Desactivate the app (turn off the screen)
• reactivate the app (turn on the screen)
• -> you get one more shot.

Any help is welcome as I am blocked on this since may days and I found no usefull information anywhere.

Also, Can you tell me if this code work on your config ?

.

.

Update: add a demo code

using a global var. Keeping the instance alive.

result

• The test2.mp3 is played and can replay fine.
• the test.mp3 is not played at all.
• It is the first file you play that will work.

Code

  function onDeviceReady()
  {
  document.getElementById("welcomeMsg").innerHTML += "Cordova is ready! version=" + window.device.cordova;
  console.log("onDeviceReady. You should see this message in Visual Studio's output window.");
  my_media = new Media("app/www/test.mp3");//ressource buildAction == content
  my_media2 = new Media("app/www/test2.mp3");//ressource buildAction == content
  }

  var playCounter = 0;
  var my_media = null;
  function playMP3(){
    console.log("playMP3() counter " + playCounter);
    my_media.play();
    playCounter++;
  }

  var my_media2 = null;
  function playMP32(){
    console.log("playMP32() counter " + playCounter);
    my_media2.play();
    playCounter++;
  }

</script>
[...]

<p onclick="playMP3();">Click to Play MP3</p>
<p onclick="playMP32();">Click to Play MP3 2</p>
