Buffer-ahead loop

[En-TACT]

I have built a flash site where I have music looping; http://www.en-tact.com/africa2010 . However, is it possible starting with the 2nd loop to buffer-ahead the start of the music?

This is what I have to just loop it:

soundTrack = new Sound();
soundTrack.attachSound("Mumbai");
soundTrack.start(0, 99999);

volumeSlider.onMouseMove = function()
{
var currentVolume = this.position._x/2;
soundtrack.setVolume(currentVolume);
};

ok, I found a function called _soundbuftime. Not working...

soundTrack = new Sound();
soundTrack.attachSound("Mumbai");
soundTrack.start(0, 99999);
soundTrack._soundbuftime = 50;
.
