We will now add an audio track to the slideshow. We will want it to play starting just after the embedded video, right up to the last slide. Click on the first slide image line after the embedded video line, then click on the 
Add transition button. Click on the Audio tab, then the click the button to open the file dialog and select an audio file. We will play the audio file on track 1 and fade in for 3 seconds, then fade out for 3 seconds. Select the 'Insert before slide' radio button, then click on the Ok button.
We have the audio track in the right place, so now it is time to move on to the next step, adding transitions.
