I have found that the best fix for this bug is to re-write the sound functionality in AS 3.0:

import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLRequest;

var song = "demo.mp3";
var snd:Sound = new Sound();
var channel:SoundChannel = new SoundChannel();

function playMusic(songSource:String){
var req:URLRequest = new URLRequest(song);
snd = new Sound();
snd.load(req);
channel = new SoundChannel();
channel = snd.play();
}

function stopMusic()
{
channel.stop();
}

A fix for this without a rewrite would be most appreciated.
