Thread: Playing sound each time mouse is clicked (not working)

Hey guys, I'm really stumped. I have a chat program and figured it'd be nice to add sound alerts for new messages, but it's not playing sound at all now.

        private class AudioClip extends Thread implements ActionListener{		
		private InputStream in;
		private AudioStream as;
 
		public void run(){
 
		        //Open audio stream
			try{
				in = new FileInputStream("alert.wav");
				as = new AudioStream(in);
				AudioPlayer.player.start(as);
 
				Timer time = new Timer(5000, this);
				time.setRepeats(false);
				time.start();
 
			}catch(FileNotFoundException e){
				e.printStackTrace();
			}catch (IOException e){
				e.printStackTrace();
			}
		}
 
		public void actionPerformed(ActionEvent event) {
			AudioPlayer.player.stop(as);
		}
	}

This is in the chat portion and happens each time a message pops up:

        if(playAudio){
		new AudioClip();						
	}

EDIT: Got it! I was in a hurry and forgot '.start()' haha
