Slideshare provide no way to move an audio file without losing all the timings, nor do they respond to questions or feedback on this matter. As such you'll want to listen to the audio at http://users.on.net/~perltraining/hiveminder.mp3 while you page through the slides yourself.
I'm not uploading any more presentations to SlideShare. Check out http://www.youtube.com/user/pjfenwick for all my other presentations, which *do* have their audio in sync.
