Android home button does not suspend my app

Hi,

I have an app built in Edge Animate and then packaged in Phonegap Build.

The app works fine and does what it should. However on Android, when I press the home button, the app does not suspend - or at least the audio does not.

Is there a technique to use the event of pressing the home button on the device to pause or mute the audio?

I have tried

     document.addEventListener("pause", onPause, false);

in compositionReady and creationComplete as well as in my html, and with it

     function onPause() {

        my_MUSIC.pause();

     }

I am using Cordova's media plugin to control the audio as EA's native system does not seem to work with Android builds. So my audio loop command looks like this:

     function loopMUSIC(url) {

          // Play the audio file at url

          my_MUSIC = new Media(url,

          // success callback

          function () {},

          // error callback

          function (err) {},

          //Loop audio

          function (status){

               if (status === Media.MEDIA_STOPPED){

                    my_MUSIC.play();

               }

          });

          my_MUSIC.play();

     }

Any ideas gratefully received, thanks
