I hear about this problem lots and lots: “I created my presentation, sent it (via CD, email, intranet, etc) and the other person sees the presentation but does not hear the music – what happened?”

PowerPoint is limited in its ability to embed any multimedia, instead it links to an external file and plays it. So when you add an .mp3 music track to a presentation – it is not inside (embedded) with the presentation – and it MUST be distributed with the presentation for it to work. Here is the best practice:
– Copy the selected audio file to the same folder as the presentation
– Insert the audio file into the presentation
– Always send a copy of the presentation AND the audio file

Next, the exception to the rule.
