If you want to play Audio CD during slide show, please see "Play a CD during
a presentation" in the PowerPoint Help.
If you add sound file to the presentation "Add and format sound in a
presentation" in the Help tells you how to do it also. When you select the
sound file, the Sound panel will be available in the Formatting Palette.
You can hide the sound file during the slide show and you can loop playing
the sound file while your slide show is running.
