Hi Jean,
You can make it disappear during slide show by choosing the "Hide while not
playing" setting for the sound file. How this is done depends on the
version of PowerPoint that you are using.
PPT 97/2000 -> Slide Show -> Custom Animation ... Play Settings tab in the
dialog
PPT 2002/2003 -> Slide Show -> Custom Animation ... Effect Options (from
effects drop down menu in Custom Animation task pane)
