JPlayer not playing music from localhost

Question

I am trying to play music from localhost using JPlayer but it is not working on Opera.

$(document).ready(function(){
  $("#jquery_jplayer_1").jPlayer({
    ready: function () {
      $(this).jPlayer("setMedia", {
        title: "Bubble",
        mp3: "demo.mp3",
        oga: "demo.ogg"
      });
    },
    cssSelectorAncestor: "#jp_container_1",
    swfPath: "js/swf",
    supplied: "mp3, oga",
    solution:"html,flash",
    wmode:"window" 
  });
});
