Unison Audio in a Converted PPT not playing

If the audio on a converted PowerPoint is not playing, this is likely due to the audio file not being embedded in the PowerPoint before being converted. To ensure that the audio is embedded in the PowerPoint, you must:

 

1- Make sure that the file is .wav format. PowerPoint will not embed .mp3 files

2- Click Insert, Sound, Sound from File

3- Browse for your .wav format audio file. Select the button that says “Automatically” when prompted. PowerPoint will then add an audio icon to your PowerPoint page, which you can place anywhere on the page.

4- Be sure that the Max Sound File Size is greater than the size of your audio file.

PowerPoint 2007 (PC version): this setting is found by selecting the icon for your audio file on your PowerPoint page, and adjusting the Max Sound File Size located at the top of the PowerPoint window.

PowerPoint 2003 (PC version): this setting is found by selecting the icon for your audio file on your PowerPoint page, selecting Tools; Options, and under the General tab, adjusting the number where it says “Link sounds with file size great than”

On a Mac, you adjust this setting by entering the PowerPoint Preferences, and under the General tab, change the number where it says “Link sounds with file size greater than:”

By default these amounts should be set to 100. It is suggested that you set this number to the 50000 maximum size to ensure your files embed properly.

Powerpoint 2010 for Windows and Powerpoint 2011 for Mac do not require you to change the file size, this is done automatically for you after bringing the audio file into the ppt slide. As long as the audio file is in a .wav format, just drag and drop.
