I’m trying to add narration to my PowerPoint 2010 presentation. The built-in narration tools are unsuitable because there isn’t a way to edit it. So, I used Audacity to create the narrations and CDex to convert them to wave files.
All are in the same folder as the PowerPoint. They are inserted [embed] in each slide with a duration of 999. Each plays fully except when I switch to Slide Show. Then the play for each only lasts 4 seconds.


Ideally, it would be nice for them to play as narrations. But, they need to play in their entirety. If I could replace the PowerPoint narration files with my wav files it would be perfect.
