how to stop all audio players playing if one player is selected?

Question

I have a demo here: demonstration

In the demo I have 2 questions and in those questions it contains jplayer audio players where it plays audio which belongs to each question.

So in demo question 1 has 2 pieces of audio, hence why there are 2 audio players for question 1, one audio file per player. In question 2 it has one audio player as it only contains one audio file. Now code below displays this where if a question has no audio file, then display a blank else display audio players for each audio file.

Only problem is that if you click on an audio player, then all audio players are playing, playing their files. All I want is that if a user uses a audio player, only the audio file that belongs to that audio player should play and that is it. This is same for the other controls, if user uses a control in an audio player, then it only control that audio player only.

But what do I need to do in order to fix this?

Below is code:

<?php

foreach ($arrQuestionId as $key=>$question) {

?>

<div class='lt-container'>
<p><?php echo htmlspecialchars($arrQuestionNo[$key]) . ": " .  htmlspecialchars($arrQuestionContent[$key]); ?></p>

<?php

        //start:procedure audio
        $aud_result = '';
        if(empty($arrAudioFile[$key])){
          $aud_result = '&nbsp;';
        }else{

$j = 0;
foreach ($arrAudioFile[$key] as $a) { 

        $info = pathinfo('AudioFiles/'.$a); 
?>

<script type="text/javascript">   
    $(document).ready(function(){
  $("#jquery_jplayer_1-<?php echo $key.'-'.$j; ?>").jPlayer({
    ready: function () {
      $(this).jPlayer("setMedia", {
        <?php echo $info['extension'];?>: "<?php echo "AudioFiles/".$a; ?>"
      });
    },
    solution:"flash,html",
    swfPath: "jquery",
    supplied: "<?php echo $info['extension'];?>"
  });
}); 
</script>
  <div id="jquery_jplayer_1-<?php echo $key.'-'.$j; ?>" class="jp-jplayer"></div>
  <div id="jp_container_1" class="jp-audio">
    <div class="jp-type-single">
      <div class="jp-gui jp-interface">

      </div>

  </div>
<?php $j++; 
}

}
//end:procedure audio
?>

</div>


<?php

}

?>

UPDATE:

  $("#jquery_jplayer_1-<?php echo $key.'-'.$j; ?>").jPlayer({
    ready: function () {
      $(this).jPlayer("setMedia", {
        <?php echo $info['extension'];?>: "<?php echo "AudioFiles/".$a; ?>"
      });
    },
    $(this).bind($.jPlayer.event.play, function() { //ERROR HERE
      $(this).jPlayer("pauseOthers");
    },
    solution:"flash,html",
    swfPath: "jquery",
    supplied: "<?php echo $info['extension'];?>"
  });

Code above giving me this error: missing : after property list

We ran into this on a recent project. See this jPlayer demo:

http://www.jplayer.org/latest/demo-03/

According to that page, "Additional $.jPlayer.event.play event handlers have been used to avoid the jPlayers playing together."

Add the play function in the jPlayer properties, like this:

  $("#jquery_jplayer_1-<?php echo $key.'-'.$j; ?>").jPlayer({
    ready: function () {
      $(this).jPlayer("setMedia", {
        <?php echo $info['extension'];?>: "<?php echo "AudioFiles/".$a; ?>"
      });
    },
    play: function() { // To avoid both jPlayers playing together.
      $(this).jPlayer("pauseOthers");
    },
    solution:"flash,html",
    swfPath: "jquery",
    supplied: "<?php echo $info['extension'];?>"
  });
