Answer 1

停止播放所有声音

import flash.media.SoundMixer;
SoundMixer.stopAll();

要停止一个声音，您必须使用SoundChannel

import flash.media.Sound;
import flash.media.SoundChannel;
import flash.net.URLLoader;
var mySound:Sound = new Sound();
var myChannel:SoundChannel = new SoundChannel();
mySound.load(new URLRequest("myFavSong.mp3"));
myChannel = mySound.play();

// ...

myChannel.stop();
