No audio from Mac laptop during PowerPoint embedded video

Check those internal audio settings

The cause of a Mac laptop computer's failure to play the audio track of a PowerPoint-embedded video clip is most likely traceable to the laptop's internal audio settings, which need to be changed to ""Crestron" when it is connected to the room's AV system. This issue is largely Mac specific and much less likely to occur when presentations are run from the podium computer.
