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?
