Beyond Bullets (continued)

By popular demand from the commenters, here is the trick to creating a backing track to a powerpoint slide show. This comes courtesy of Cliff Atkinson of Beyond Bullets:

The trick here is to embed the sound file into the first slide. Then right click the sound icon as described below, and set “Stop Playing” to “After 99999” Slides. That should do the trick.

To adjust settings for when the sound file stops: click the sound icon , right-click, and on the shortcut menu, click Custom Animation.
In the Custom Animation task pane, click the arrow on the selected item in the Custom Animation list, and then click Effect Options.
On the Effect tab, under Stop playing, do one of the following:
To stop the sound file on mouse-click of the slide, select On click (the default).
To stop the sound file after this slide, click After current slide.
To keep the sound file playing for several slides, click After, and then set the total number of slides the file should play on.
