I'm just starting to work with Powerpoint. I follow all the instructions about not using mp3 files but WAV files--nevertheless, I still can't get the sounds to work at all. Looking at previous posts and links, the issue may be that sounds play, not in wmplayer, but in mciplayer. I don't, however, seem to have mciplayer on my system--at any rate, nothing happens when I put mciplayer in Run on the Start bar. Can anyone please help and move me forward.
