<StackPanel>
<!-- The MediaElement control plays the sound. -->
<MediaElement Name="myMediaElement" />
<Button>Click to Hear a Sound!
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<!-- Sound wave from this source is played when the button is clicked.-->
