Files not working

straight to the point --- ive got an image on one of my pages, made a couple of image maps on it, using the onClick-Playsound method, its suppose to play audio files, on my computer, the files play, on memory stick, when i burn it to CD, any other computer, it doesnt work, all the file linking and directory are in order and and nothing is wrong with audio file or format, is there something im not quite getting here, heres an example of the source of the image map-file location:

<p align="left" class="style1"><img src="Book%20Shelf/images/1.jpg" width="300" height="400" border="0" usemap="#Map">
<map name="Map">
<area shape="circle" coords="169,291,21" href="#" onClick="MM_controlSound('play','document.CS1205012999057', 'Book%20Shelf/lockShelf/Audio/left_Audio/4.wma')">
</map>

try changing Book%20Shelf, to bookshelf and see if it works
