Salut
J'ai eu besoin de cela aussi une fois, voici ce que j'avais trouvé qui rejoind la réponse de BULTEZ avec le volume en plus
<HTML>
<HEAD>
<bgsound src="#" id="soundeffect" loop=1 autostart="true" volume=-1500 />
<script type="text/javascript">
/***********************************************
* JavaScript Sound effect- © Dynamic Drive DHTML code library (www.dynamicdrive.com)
* Visit 
[ Lien ] for hundreds of DHTML scripts
* This notice must stay intact for legal use
***********************************************/
var soundfile="son1.wav" //path to sound file, or pass in filename directly into playsound()
function playsound(soundfile){
if (document.all && document.getElementById){
document.getElementById("soundeffect").src="" //reset first in case of problems
document.getElementById("soundeffect").src=soundfile
document.getElementById("soundeffect").volume='10'
}
}
function bindsound(tag, soundfile, masterElement){
if (!window.event) return
var source=event.srcElement
while (source!=masterElement && source.tagName!="HTML"){
if (source.tagName==tag.toUpperCase()){
playsound(soundfile)
break
}
source=source.parentElement
}
}
</script>
</HEAD>
<BODY>
<DIV><a href="#ancre1" onMouseover="playsound('chemin .wav');">test de son</a></DIV>
</body>
</html>
