I have been trying to record a short video using the add-in on PowerPoint '13 but the audio is always out of sync! It is out of synch right from the beginning. I am using all the standard settings. Even when I do a brief (<1 minute) test video the audio is out of sync. I am using version 8. I never had any problems like this when I was using version 7. I am using a Dell Optiplex 7010 with an upgraded processor. No other programs are used while recording. The system is set for best performance. What do we need to do to make it work?!?
