I used the full EMBED with the clip selected in the SRC=""; I use Claire de Lune, HIDDEN="false" to show the control panel for the media player if someone wnants to shut off the clip, AUTOSTART="true" to start the clip on entry to the page, though it still took time to load and LOOP="true" to make the clip play repeat. it id in the sound clip tutorial. Vist my site to see it at work. Be sure that you have the clip in your file manager (or as I say file mangler:)).
A useful way to gain understanking is to use "View soruce" to see how the thing you are looking to learn about is set up.
