Need help controlling audio object volume in iE8

I'm very much a noob at this but I've got my .wav files playing sound effects and even overlapping when I need them to in Safari, Chrome, IE and FireFox but the only problem I still have is I can't set the volume in IE8. It just plays at the same loud level of the original file. Here is the code I have (with things I've tried commented out).

this.load = function( audiofile )

    {

    var i;



    for ( i=0; i<overlapMax; i++ )

        {

        var object = null;



        if ( ie8 )

            {

            object = document.createElement('div');

            var iesound = '';



    //      adding volume here didn't do anything

    //      iesound = iesound + '<object id="'+soundID+'track'+i+'" type="audio/x-wav" volume=2 data="'+audiofile+'" width="200" height="16">';



            iesound = iesound + '<object id="'+soundID+'track'+i+'" type="audio/x-wav" data="'+audiofile+'" width="200" height="16">';

            iesound = iesound + '<param name="src" value="'+audiofile+'" />';

            iesound = iesound + '<param name="volume" value="2" />';  // adding volume here didn't do anything          iesound = iesound + '<param name="autoplay" value="false" />';          iesound = iesound + '<param name="autostart" value="0" />';         iesound = iesound + '<param name="pluginurl" value="http://www.apple.com/quicktime/download/" />';

            iesound = iesound + '</object>';



            object.id = soundID+'track'+i+'div';

            object.innerHTML = iesound;

            object.style.visibility = 'hidden';

            object.style.position = 'absolute';

            object.style.left = '0px';

            object.style.top = '0px';

            }

        else

            {

            object = document.createElement('audio');

            object.setAttribute('id',soundID+'track'+i);

            object.setAttribute('src',audiofile);

            }



        document.body.appendChild( object );



        var newsound = document.getElementById(soundID+'track'+i);



        // needs to be handled with a method & params

        //

        newsound.volume = 0.02; // this sets volume just fine for everything but ie8



        tracks.push( newsound );

        }

    }
