PowerPoint slides presentation with audio don't play. -- Codec problem.
Hi, I have a PowerPoint 2016 slide presentation (.pptx) that was created on a Windows 10 machine. We tried to play the presentation on another Windows 10 machine with PowerPoint 2010, but it did not play the audio. The slides all show the little speaker icon on the lower right corner of the slides, but there's no audio. -- If I hover my mouse over the little audio icon and try to play the audio, it says "Codec Unavailable." -- If I move the file back to the PowerPoint 2016 machine, it will play correctly.
So, in summary...the audio is there, but PowerPoint 2010 will not recognize the audio codec on the PowerPoint 2010 machine.
We tried to run the "Optimize Media Compatibility" form within PowerPoint 2016, but it will not allow us to do that. Apparently, PowerPoint 2016 thinks there aren't any compatibility issues.
So, my question is...how do I fix this?
I can't assume that end users will have the latest version of PowerPoint to play our presentation.
How do I identify the codec and how do I make sure I have the right one?
Thanks,
Fulano

Jamie, thanks for the comment, but I don't think its my OS. The problem is happening on multiple machines and all those machines can play everything and anything, except for these PP files. The only difference between the machines is the version of PowerPoint. The slides were created on PP 2016 and the other machines are running 2010.
I'm going to upgrade the version of PP on all those machines from 2010 to 2016 this weekend and check if that fixes the issue. I'll close out the question after this weekend.
Thanks,

Hi Jamie, sorry for the delay...this took a little longer than I expected to test. - In the end I performed the ZIP file test you suggested. The media files ARE within the media folder, however, they will not play with Windows Media Player, but do play with whatever player is used in the folder side panel view in Windows. To tell you the truth, I have no idea why they're not playing, but I was able to resolve the issue with upgrading to PP2016. Hopefully the proper codec will be included with the slides when I transfer then to another user.
That said, I am awarding you the points for your help. Thanks you again.

In terms of avoiding issues, I would suggest using WAV for importing your audio files and then run the optimise media tool before distributing the presentation.
