I have seen the audio player at http://next.liberation.fr/musique/20...-22-ans_847686 and tried to use it on my website at http://www.learnintouch.com/elearnin.../subscription/ but it does not want to play the audio file. This happens to the latest Firefox 15.0.1 only. You need it to see the issue. I guess it is related to the Flash version within the browser. But I can't see why my markup code does not work, when the other one does.

Thanks for any tip !
