title: Make jPlayer play again without page reload
body: <p>Our users us IE7 and I need to play a sound if there are alert messages for dispatchers.</p>
  
  <p>This works fine when the page is loaded but if the dispatcher leaves a page open and messages have been received previously and responded to.... then when new messages are received, the sound does not seem to work.</p>
  
  <p>What am I doing wrong in using jPlayer? I just want to play the sound continuously as long as messages are there.</p>
  
  <p>My Ajax call </p>
  
  <pre><code>$.ajax({
      type: "POST",
      url: "/Messages/ViewMessages.aspx/GetMessages",
      data: "{messageId:" + 45 + "}",
      contentType: "application/json; charset=utf-8",
      cache: false,
      dataType: "json",
      timeout: 60000,
      success: function(data) {
          if (data.d.length &gt; 0) {
              showPanic(data.d);
              var sound = "/JavaScript/jQuery/UI/js/Audio/Air Plane Ding-SoundBible.com496729130.mp3";
       playSound(sound);
          }
          else {
              $("#dialog").dialog("destroy");
          }
  
      }
  
  function playSound(sound) {
              $("#jquery_jplayer_1").jPlayer({
                  ready: function() {
                      $(this).jPlayer("setMedia", {
                          mp3: sound
                      }).jPlayer("play");
                  },
