This is tricky since Acrobat is not designed to do this. After looking
at a PDF mark reference, I found that sounds and movies can be inserted
into Acrobat using the same pdfmark, hence see here:
http://wikiprosper.bbclone.de/index.php?pagename=HowtoIncludeVideo
and change the filename to your sound file.
This creates a button that you can click and will produce the sound.
You can but this construct on a custom template and click the button
when the new slide is there. There might be was to automatically
start this sound in displaying the link, but I didn't find the pdfmark
annotations for that.

It is actually more related to hyperref, pdfmark and PDF ;)
