Hello,
I am using JOAL in a university project to insert sound.
I want to prepare a little test program to learn JOAL.
I have a very simple model that uses change listeners (from Swing) to notify a change. Then I have a small controller that handles sound control acording to the model.
And I have the main class that implements the app controller which shall modify the model acording to certain key pressed.

So, to sum up: the user hit a key to move the sound in the 3D audio environment. The app controller modifies the model in consequence. The model notifies the sound controller described above, to move it acording to these changes.

But, there is a problem... The sound denies to move and to update its position.
I am really blocked on this problem...
Can someone help me please?
You will find all my code below.
Bee is the model. SoundingBee is the small controller for the sound rendering of the model. Test is the main class.

Huge thank in advance.
Regards.
