Originally the script below was working in Safari however after Apple released Safari Version 5.1.2 (7534.52.7) the script stop working. I've test in Chrome, FireFox, Opera, IE9 it works. First time I've ever had an issues like this with Safari. Any suggestions on a solution to this problem is welcome and very appreciated.

jQuery code:
$( function() {
    var $volume = $( '#volume' );

    // Buzz audio library

    buzz.defaults.formats = [ 'ogg', 'mp3','wav','acc' ];

    var Sound = new buzz.sound( 'sounds/music' );

    if ( !buzz.isSupported() ) {
    Sound.loop().play().fadeIn( 5000 );

    // Volume button

    $volume.click( function() {
        if ( $( this ).hasClass( 'all' ) ) {
            $( this ).removeClass( 'all' ).addClass( 'none' );
        } else if ( $( this ).hasClass( 'none' ) ) {
            $( this ).removeClass( 'none' ).addClass( 'all' );
        return false;
