Firefox not playing OGG audio

I have created ogg files by simply saving mp3 files "save as" ogg. But firfox is still not playing. They were playing 2 weeks ago so Im confused whether firefox changed something.

Following is my code. Please let me know if I had to save ogg files in some specific sample rate or something

// creation complete

try {

    yepnope({

        load: "http://cdn.edgecommons.org/an/1.0.2/js/min/EdgeCommons.js",

        callback: function() {

    var assetsPath = "wp-content/uploads/audio/";

    EC.Sound.setup(

         [

                {src: assetsPath + "bgMusic.mp3|" + assetsPath + "bgMusic.ogg", id: 'bgMusic'},

                {src: assetsPath + "click.mp3|" + assetsPath + "click.ogg", id: 'click'},

         ],

         function(){ EC.info("Sound setup finished", "Sound with Edge Commons"); }

    );

            }

    });

}

catch(error) {

    console.error("sw", error);

}

following is the setting I used in Adobe Edge

Following is the information that appears on my server where I upload the music
