Hi,

Are you sending the presentation out on a CD? If so have you tried this?

1. Click on the Microsoft Office button in the upper right-hand corner of your screen.
2. Click on Package for CD
3. Make sure the linked files are included by default, and then click on the Options button
4. Make sure there's a dot next to "Viewer Package."
5. Click OK to get out of the box.

Now click on "Copy to CD" and see if the music plays when you send it out.
