Flex：如何改變EMBEDDED聲音的音量？

Question

尋找如何改變聲音的音量，我總是得到這個惱人的snd=new Sound(URLRequest)，其次是snd.setVolume(val)。哦，很好，但我的聲音不是URLRequest，它是一個嵌入。

我做了很多隨機嘗試（1）無濟於事。我應該怎麼做呢？

（1），其包括鑄造我的類聲音，創建與所述嵌入類作爲參數，創建的SoundTransform並將其設置到信道一個聲音等

Answer 1

實例化嵌入類這樣的：

[Embed(source="MySound.mp3")] 
public var soundClass:Class; 


protected function application1_creationCompleteHandler(event:FlexEvent):void 
{ 
    var smallSound:Sound = new soundClass() as Sound; 
    var trans:SoundTransform = new SoundTransform(.01); 
    smallSound.play(0,0,trans); 
} 

更新：

如果你真正想知道的是如何改變音量，如果聲音已經播放：

[Embed(source="MySound.mp3")] 
public var soundClass:Class; 
public var smallSound : Sound; 
public var vol : Number = 0.01; 
public var trans : SoundTransform; 

public var chan : SoundChannel = new SoundChannel(); 

protected function application1_creationCompleteHandler(event:FlexEvent):void { 
    smallSound = new soundClass() as Sound; 
    trans = new SoundTransform(vol); 
    chan = smallSound.play(0,0,trans); 
} 

protected function volUp_clickHandler(event:MouseEvent):void { 
    vol += .1; 
    trans = new SoundTransform(vol); 

    chan.soundTransform = trans; 
}
