FAQ: Why won't the sound play from my Interactive PDF?
You might not be able to listen to the sound of the audio file because most Macintosh computers use the Preview Application to view Adobe PDF files. To benefit from the interactive features of the file, download the most recent version of Adobe Reader --Don't worry it's a FREE application. If you currently have Adobe Reader installed in your computer, right-click on top of the file and select Adobe Reade to open the file. I would recommend setting Adobe Reader as your default PDF reader.
