Closing a clip

[elamre]

Hello, i have a big memmory leak in my program, and ive found the problem. But i cant seem to fix it correctly. Im making a towerdefence game, every tower has his own thread. Then as soon as the tower will shoot, it will play a sound. Here it goes wrong. I have to close my clip (otherwise my game will run out of memmory) but i have to close it only AFTER the sound is done. Here is my playSound function:

	private void playSound(String filename) {
		 File soundFile = new File(filename);
		 
			AudioInputStream sound = null;
			try {
				sound = AudioSystem.getAudioInputStream(soundFile);
			} catch (UnsupportedAudioFileException e) {
				e.printStackTrace();
			} catch (IOException e) {
				e.printStackTrace();
			}
		    DataLine.Info info = new DataLine.Info(Clip.class, sound.getFormat());
		    Clip clip = null;
			try {
				clip = (Clip) AudioSystem.getLine(info);
			} catch (LineUnavailableException e) {
				e.printStackTrace();
			}

			try {
				clip.open(sound);
				sound.close();
			} catch (LineUnavailableException e) {
				e.printStackTrace();
			} catch (IOException e) {
				e.printStackTrace();
			}

		    clip.addLineListener(new LineListener(){public void update(LineEvent event){}});

		    clip.start();
		    try {
				Thread.sleep(100);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		    clip.close();
		    clip.flush();
	}

I have tried several solutions (clip.isOpen, clip.isRunning but nothing seems to solve my case)

Any help on closing the clip AFTER its done playing?

Also if im increasing the delay it will work. But not the way i want to (now it shoots 500 ms after you hear the sound. And if you are upgrading a tower the whole game will freeze, and the delay isnt long enough for that.
