Well, It is because the .wav music is linked to your PowerPoin
presentation, when you email to others, the linked music will not b
shown.
The difference between linked and embedded, please view:

You can do as follows:
1. Put the presentation and .wav music and other inserted files to
same folder.
2. Reinsert these files to PowerPoint presentation. After you do thi
work, zip and send the file to others. Then the music can be shown.
Alternatively, you could try to convert your presentation to Flash an
send the Flash file to other computer. The music will be embedded i
Flash presentation. And then you could show the .wav music automaticall
on other computer.
