import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.SourceDataLine;

2. Initialization:

private final int BUFFER_SIZE = 128000;
private File soundFile;
private AudioInputStream audioStream;

private SourceDataLine sourceLine;

3. Play Sound Method:

public void playSound(String filename){
    // Open the sound file
