Captivate 5 - Slidelet with audio when clicking

If all you need to do is trigger an audio file to play you could just use a rollover caption or rollover image object to do this.  Just attach the audio to the caption or image that appears on rollover.  Then the audio will start to play as soon as the image or caption becomes visible.  If you want to hear the audio but not see the image or caption, just drag it off stage so that it won't be visible to the user.

The above solution works where rollover is all you need.

If on the other hand you want to trigger the audio on click, then attach the audio to the Success caption of a button or click box object.  Once again, if you don't want to see the caption, just drag it off stage or convert it to a transparent caption with no text so that it is effectively invisible.

If you need to trigger audio by clicking some other object, you can use the Event Handler widget (http://www.infosemantics.com.au/catalog/widgets/interactive/wdgt_event_handler_01) and attach the audio to its Success caption.  This widget gives you the option of triggering the Success on just about all mouse actions you can think of, including rollover, rollout, click, mouse down, mouse up, double-click, and even right click.
