I work for a university. Some faculty distribute their lectures as Powerpoint slideshows with embedded audio. The audio works fine for most students, but a few are having issues. All the students have Powerpoint 2010.
If I extract the audio from the Powerpoint slide (by changing it to a zipfile), the audio clips play just fine on the student's computer. This ensures it is not a problem with the audio being embedded improperly or using a codec they do not have available.
Suggestions?

Over a year later, I found the answer!
The issue is related to execution protection. If you remove the 'fetched from the Internet' attribute from the file then Powerpoint will play the audio.
Solution: Just click Unblock on the bottom of the properties for the PowerPoint file. When you next open it, the audio will play.
1That's a weird one for sure... :) If the workstations in question are running Vista or 7, ensure that PowerPoint hasn't been muted/turned down in the audio Mixer (Vista+ allows per-application volume settings in the mixer).
I had the same problem. I checked the properties and the file was not blocked. Eventually I discovered that I had to download DivX software to play the audio
