Hello Carlos,
Can you please answer David's questions? If the answer is yes to the first
question, can you please give us some exact repro steps and indicate which
exact model of MacBook Pro you have? Go to Apple Menu > About This Mac... >
More Info and indicate the machine model (example: MacBookPro1,1). Also, it
would help to know the exact version of PowerPoint you have (go to
PowerPoint menu > About PowerPoint).
Also, can you tell me what happens if you do this?
1. Start PowerPoint
2. Insert > Movies and Sounds > Sound From File...
3. Select a file from the Microsoft Office 2004/Office/Sounds folder [let
me know which you chose from there]
4. Insert
5. Answer No at the prompt
6. Double click on the sound in the presentation
7. Start Slide Show
8. Repeat step 8
The above will help us in trying to narrow down the issue. If the file
doesn't play, what if you use QuickTime Player to play it?
Andrew
