Play sounds with Java on a Mac

Question

Alright, before I post any code, here's my specs:

• Computer: Macbook Air, Early 2014 model
• Java version: Java 8, Update 65 (Java Control Panel says I'm using the recommended version)
• OS Version: OS X El Capitan, 10.11.1

Now that that's out of the way, I use Terminal as a Console window, java to run, and javac to compile. I have a class in my project dedicated to playing sounds. The complete code for it is below:

package javacoffeeadventure.audiomanager;

import java.io.*;
import javax.sound.sampled.*;
import javacoffeeadventure.io.FileIO;
import javacoffeeadventure.commandinterpreter.*;

public class AudioManager {

    public static void playSound(String soundName) {
        try {
            FileIO f = new FileIO();
            AudioInputStream ain = AudioSystem.getAudioInputStream(f.getURLForResource("sounds/" + soundName));
            Clip clip = AudioSystem.getClip();
            clip.open(ain);
            clip.start();
        } catch (Exception ex) {
            javacoffeeadventure.commandinterpreter.Console.sharedConsole().error("Exception while playing sound " + soundName + ": " + ex.getMessage());
        } finally {

        }
    }

}

Where...

• javacoffeeadventure is the top-level name of the package
• commandinterpreter.Console is a way to do stuff quickly with the Console (I had to use the full name because java.io.Console already exists)
• javacoffeeadventure.io.FileIO is a simple way to handle resources and load/save a file
• I'm playing a wav file

Either way, I'm using javax.sound.sampled.AudioInputStream , javax.sound.sampled.AudioSystem , and javax.sound.sampled.Clip to play sounds.

When invoking clip.start() , the following error occurs:

2015-11-15 21:23:08.195 java[77192:2681680] 21:23:08.195 WARNING:  140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

This tells me Java uses an obsolete framework, CarbonComponent.h , to play sounds, and OS X suggests Java transition to AudioComponent.h .

Is there a workaround available so I can play sounds without using deprecated methods and avoiding unnecessary exceptions?

Edit

The Java Sound API works , but it outputs this when letting the Jukebox play:

Answer 1

This is because OpenJDK is binding to openal-soft for this and it currently depends on Carbon.

There is an open issue on OpenJDK: https://bugs.openjdk.java.net/browse/JDK-8138754

It has been fixed in the master branch of openal-soft : https://github.com/kcat/openal-soft/issues/20

It has not been released as of openal-soft 1.17.0 which is the latest release available as I write this.

It should be possible to build an install a newer openal-soft to fix this. It may be already available in Homebrew.

You can build from source, but I recommend basing your code on the Java Sound API example and documenting this message as a known issue for now as openal-soft has been fixed and its release is outside your control.
