LIBGDX - Error creating music

votes

I'm attempting to simply load a Music asset using libgdx, and this is what I have:

Music main_background;
main_background = Gdx.audio.newMusic(Gdx.files.internal("data/music/main_bg.wav"));

This code is exactly the same code as they have in the small tutorial of "Making a game" with libgdx, and I'm trying to load my own sound that I have made (Using GarageBand, in case that matters). Whenever I try running this as a Desktop application, I get a bunch of errors:

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: Error creating music com.badlogic.gdx.backends.openal.Wav$Music for file: data/music/main_bg.wav

Caused by: java.lang.reflect.InvocationTargetException

Caused by: com.badlogic.gdx.utils.GdxRuntimeException: Error reading WAV file: data/music/main_bg.wav

Caused by: com.badlogic.gdx.utils.GdxRuntimeException: RIFF header not found: data/music/main_bg.wav

I'm not sure what the problem could be, because the audio file isn't corrupt (because I can listen to it perfectly fine) yet I can't find information anywhere about people getting this type of error when loading an asset.

I have a bunch of Texture's loaded just fine, but for some unknown reason I can't load a Music asset (and for the record, I tried loading the same file as a Sound asset and get essentially the same error).

Has anyone come across this before or have any ideas on what could be wrong?

EDIT: I should mention I also get this error if I try loading an mp3 or ogg file as well, it doesn't just happen with a wav

Are there any other GDX log messages in the console? Maybe something about OpenAL? Also, what platform is your desktop? Do you get a different error if the file doesn't exist at all (e.g., like "data/music/gibberish.wav") – P.T.
I just tried to run my small game including the music today, and now it worked. I'm unsure what the problem was still, because I didn't change anything at all (I didn't even close and reopen Eclispe), and I had refreshed the asset directory multiple times because I thought it didn't know it existed. – Ninjalemon

First of all, know the differences between Sound and Music in libGdx. Read this: https://code.google.com/p/libgdx/wiki/Audio
The problem maybe is in bit rate. I had this problem and I changed the bitrate of wav files to 705kbps and it worked.

I had the same issue. It was solved by restarting Eclipse. It seems some SDK files had not fully installed yet and restarting Eclipse allowed them to complete the install.

You can convert it to .ogg, it occupies less space. And keep it in your data folder. Then declare a variable named music:

Music music;

After that in your create method:

music = Gdx.audio.newMusic(Gdx.files.internal("data/whoo.ogg"));

Then use it anywhere in your game - in render, touchUp touchDown anywhere you want the music:

music.play();
