Although there are various reasons why music or other audio might not play correctly in a PowerPoint presentation, compatibility is the most common cause. Learn how to troubleshoot and resolve audio playback issues in PowerPoint.

Make Sure the File Format Is Supported

If you are not using one of the following supported audio file formats, consider converting it to a recommended format and then reinserting it in the presentation.

Instructions in this article apply to PowerPoint 2019, PowerPoint 2016, PowerPoint 2013, PowerPoint 2010, and PowerPoint for Microsoft 365.

The following audio file formats are supported in PowerPoint:

  • AIFF Audio file, .aiffAU Audio file, .auMIDI file, .mid or .midiMP3 Audio file, .mp3Advanced Audio Coding—MPEG-4 Audio file, .m4a, .mp4Windows Audio file, .wavWindows Media Audio file, .wma

Optimize Media

Optimizing your audio media for compatibility is the best way to resolve audio playback issues when you share your PowerPoint presentation.

  • Go to File.
  • Select Info.
  • Select Optimize Compatibility.
  • If Optimize Compatibility appears, your media format may have compatibility issues on another device. If it doesn’t appear, there are no compatibility issues and the presentation is ready to be shared.
  • Wait while PowerPoint optimizes your audio. Once it’s done, select Close.

Compress Audio Files

Embedding audio files rather than linking to them will guarantee playback. This increases the size of your presentation, but compressing your audio files helps save space.

Go to File.

Select Info.

Select Optimize Compatibility.

If Optimize Compatibility appears, your media format may have compatibility issues on another device. If it doesn’t appear, there are no compatibility issues and the presentation is ready to be shared.

Wait while PowerPoint optimizes your audio. Once it’s done, select Close.

  • Go to File.
  • Choose Info.
  • Select Compress Media.
