If the pathname of a linked file exceeds 128 characters, Microsoft Office PowerPoint will fail to search and play that linked file. As such, it is advisable to either rename the linked file, or shorten the path name by copying the linked file into the folder where your presentation is located. Then, update them manually by removing the sounds from the presentation and then adding them again.
Add Sound Effects to Transition Pages
Transition pages are the pages that occur when you advance from slide to slide within the presentation In PowerPoint. You can add sound effects to complement the slide transition animation if desired.
To add a transition effect, choose your page, go to the Transitions tab, and choose one of the available effects in the box.
When the transition is added, find the Sound option in the ‘Timing’ section, and choose one of the available sound effects from the menu. The added sound can be previewed during the transition of pages. Hope you find this tutorial useful.
