I have noooo idea why this would happen. You might post over on the
PowerPoint group and see if anyone there has any ideas for you.
You may want to mention if it happens when the projector isn't plugged in --
I know that's my first question. Also, does it hiccup in the same place each
time? If you play the presentation through once, then does it hiccup the
second time through? How was the sound inserted? What kind of sound file is
it?
You'll be asked things like that, I'm sure, for yours is not a common
problem.
