Play sound on raspberries pi using java

Question

Hi, I have this code here

import java.io.File; import java.io.IOException; import javax.sound.sampled.AudioInputStream; import javax.sound.sampled.AudioSystem; import javax.sound.sampled.Clip; import javax.sound.sampled.LineUnavailableException; import javax.sound.sampled.UnsupportedAudioFileException; public class Playmusic implements Runnable { public static void main(String[] args){ Thread t = new Thread(new Playmusic()); t.start(); } @Override public void run() { AudioInputStream audioIn; try { audioIn = AudioSystem.getAudioInputStream(new File("test.wav")); Clip clip; clip = AudioSystem.getClip(); clip.open(audioIn); clip.start(); Thread.sleep(clip.getMicrosecondLength()/1000); } catch (UnsupportedAudioFileException | IOException | LineUnavailableException | InterruptedException e1) { e1.printStackTrace(); } } } 

to play sound on raspberries. But when I run it, it does not produce any output.
I tested it on both Windows and Linux, where it works.
The program does notice the file, though, since it sleeps for the entire duration of the sound and does not give me any Runtime exception.
It also cannot be the speaker causing the problem, because I can play the sound using aplay test.wav and it gives me the result. I wanted to use the JavaFX library, but it seems to be deleted when the java version of resbian is shortened.

This has nothing to do with Java or Raspbian ... Check your RPi sudo raspi-config configuration and make sure your audio output is well tuned between HDMI or Jack Out. That should do the trick ...
