Bob,
If you want to embed the audio file - first go to the "Button" in the upper
left - go to Options - Click Advanced - scroll down - to the Save line - you
will see the line Link sounds with the file size greater than: _____KB-
change this number to a size larger than your largest sound file - click
OK - You will need to reinsert all the audio file(s) then save your PPT. Now
the sound files will be imbedded into your PowerPoint and not linked.
