Hi everyone, I have been using the iPad 3 for a week now, after using iPhone1 and iPod for a number of years. Transition has been smooth and interesting. I have though already a trouble trying to play PPS Files with Keynote. The file plays well in any of my computers, but in the iPad, the sound does not come out from the speakers. Is this a limitation of Keynote or is it an iPad problem. Any suggestions will be appreciate.
