private var audio:Sound;  
audio = new Sound();  
.  
.  
.  
.  
audio.load(new URLRequest(FILENAME));  
audio.play();

while executing this code, i’m getting the following error.

1. type was not found or was not a compile time constant.Sound
2. call to a possibly undefined method Sound.
3. call to a possibly undefined method URLRequest.
