To embed a sound file in your web page so that it plays when the page opens,
<embed src="filename" autostart="TRUE" hidden="TRUE"></embed>
<embed src="StarWars.mp3" autostart="TRUE" hidden="TRUE"></embed>
Be sure to upload BOTH the HTML file that calls the sound file as well as the sound file itself to your i5 website. Also be sure to list any important bibliographic information if the audio clip is not copyright-free.
To use a video clip, use a link to the video file.
