Hi, I'm Trying to use the sketch demo of the toxiclibs - audioutils on ubuntu 8.10 but I've got this error :

Sorry for not replying sooner, but it's usually a better place to use the toxiclibs mailing list or issue tracker at google code than this forum for dealing with errors...

Anyway, I have no experience with using OpenAL under Linux, but I'd guess you'll need to download some drivers first:

It runs now.
Thanks

If you have another example a little more simple to can understand how works your library, it will help me a lot.

I've just uploaded a new release of this library and also prepared 3 more (simpler) examples for that occasion. get the libs from here:

http://code.google.com/p/toxiclibs/downloads/list

The most basic usage is just this:

Code:

import toxi.audio.*;
import toxi.geom.*;

JOALUtil audioSys;
AudioSource source;

audioSys = JOALUtil.getInstance();
audioSys.init();
source=audioSys.generateSourceFromFile(dataPath("test.wav"));
source.play();


Hth!
