java - Audio Clip won't loop continuously

Question

Can anyone point me in the right direction as to why this code will not play this audio clip continuously? It plays it once and stops.

final Clip clip = AudioSystem.getClip();
final AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File("Alarm_Police.wav"));
clip.open(inputStream);
clip.loop(Clip.LOOP_CONTINUOUSLY);

Answer 1

If you are running a bigger application, this answer may not apply. But for a simple test with only that piece of code, this may help:

Clip.loop() starts it's own thread, but that thread will not keep the JVM alive. So to make it work, make sure the clip is not the only thread.

If I leave out Thread.sleep(..) from this snippet, I get the same issue as you;

import java.io.File;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;

public class Snippet {
    public static void main(String[] args) throws Exception {

        AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File("notify.wav"));
        Clip clip = AudioSystem.getClip();
        clip.open(inputStream);
        clip.loop(Clip.LOOP_CONTINUOUSLY);
        Thread.sleep(10000); // looping as long as this thread is alive
    }
}
