Content: Workaround
To work around this missing slide transition sound issue, remove the transition sounds, and then add the sounds directly to the slide. The sounds can then be set to play across slides and be triggered just before slide transitions to the next slide. Note
This workaround only works if the presentation uses slide timings to advance to the next slide. Open the presentation in PowerPoint 2010. Locate the slides with the transition sounds. On the Transitions tab, set Transition Sound to [No Sound]. Under Advance Slide, note the slide duration time in the Automatically after box. On the Insert tab, in the Media Clips group, under Sound, click either Sound from file or Sound from Clip Organizer. Insert the sound that you want to play across the slide transition. Click Automatically when you are prompted.
