Wonderfull ! I'm happy !:)
OpenAlSoundManager can only play wav file with 8 or 16 bits per sample, mono or stereo.
The wav file you have posted is 24bits per sample. This is the reason there is no sound when you click play button.
On my Windows system, if I just double click on your wav file it plays also OK.
Thanks you very much Carl Caulkett and to Handoko for your interest and your precious help. I learned a lot through our discussion
