The recommended way, Is to put the sound file into the same folder as your
presentation before you insert it into your presentation, then insert it
into your presentation. Keeping in mind the only sound files that get
embedded into PowerPoint are WAV files. all others are linked that way you
can copy all the sound files onto your disc when it is completed.

I am new user of powerpoint 2003 and 2007. I have successfully made my
presentation but when copied to disc there is no sound.
