Hi

I've encountered a problem with using OpenAL. When I run my program, it shows a black screen for a second then outputs the following error file. I'm using LWJGL 2.9.3 on Mac OS X Yosemite. My OpenAL code looks like this.

public static void playAudio() {
      WaveData data;
      try {
         data = WaveData.create(new BufferedInputStream(
               new FileInputStream("forrest.wav")));

         int buffer = alGenBuffers();
         alBufferData(buffer, data.format, data.data, data.samplerate);
         data.dispose();
         int source = alGenSources();
         alSourcei(source, AL_BUFFER, buffer);
         alSourcePlay(source);
         alDeleteBuffers(buffer);
      } catch (FileNotFoundException e) {
         e.printStackTrace();
      }
   }


Can anyone shed some light on this problem?

Thanks, DarkCart

You delete it as its playing?

Also, you can encounter this when you use a faulty file. Get a new sound file.

You think I haven't been monitoring the chat? http://pastebin.java-gaming.org/c47d35366491fHere is a compilation <3

Already tried removing the lines that delete it, nothing happens. The audio file is fine. I already tried a different file, still didn't work

I don't see where you are creating a context. You have to create a context before you can use it's functions.

1  
AL.create();


and finally you also have to destroy the context.

Do you suspend the thread like this?

while(!Display.isCloseRequested()) {
Display.sync(60);
Display.update();
}


Or LWJGL3 way?
