4. Check if the audio/video format is supported.

This brings us to the likely crux of the matter. If you cannot play video or audio in a PowerPoint presentation, chances are you are using an unsupported media format.

As for audio, PowerPoint 2010 uses mostly WAV files! For example, if you use an MP3 file in your presentation, you may experience problems.

In PowerPoint 2016, things are a little better. In addition to .wav files, this version also supports .m4a files encoded with AAC audio. The operation of any other format is not guaranteed.

Perform a system check for possible errors

Press Start Scan to find problems with Windows.

Press Repair All to troubleshoot proprietary technologies.

Scan the PC with Restoro Repair Tool to find errors that cause security problems and slowdowns. Once the scan is complete, the damaged files are replaced with new Windows files and components.

As with video, the choice of compatible formats is also very limited. Microsoft recommends .wmv files for PowerPoint 2010, while version 2016 adds .mp4 files encoded with H.264 video and AAC audio.

Microsoft also notes that Flash videos may not work in newer versions of PowerPoint (2013 and 2016).

5. Convert an audio or video file

Like we said, even if PowerPoint supports your current video or audio format, it’s always best to convert it to .wmv/.wma.

Fortunately, there are dozens of tools that can convert your media in no time. And since the choice is quite large, we have compiled a list of the best audio/video converters for Windows.

If the PowerPoint sound doesn’t work, then you need to use a file converter and hide it in an appropriate template.

  1. Navigate to Tools > Options.
  2. Select the General tab.
  3. Set link sounds with a file size greater than 500,000 KB (or any size larger than the file you are trying to insert).
  4. Click OK to save your changes.

Although it is recommended to use .wma files, this may not be practical. Mainly because .wma files are larger than other formats. And since PowerPoint has a little thing called limited reference value….

This option does not allow you to include large files in your presentation. If your file exceeds the limit, you cannot integrate it.

So if the TPP can’t play the media, try this little trick.

7. Delete the TEMP folder

  1. Press the Gain + R button.
  2. In the Run window, enter the following path: %temp%
  3. Select all files with the extension TMP.
  4. Delete files.
  5. Restart your computer.

There are tons of temporary files stored in the TEMP folder that can affect PowerPoint. So, if you are sure you are using the right formats and have all the necessary codecs installed, try deleting this folder.

I hope this will help you if the PowerPoint sound doesn’t work.

So here are some ways to correct a PowerPoint presentation that doesn’t play video and audio.

Make sure the media file formats are PowerPoint-compatible and have the required codecs.
