Been wrestling with apache2 on Laptop for a bit trying to get extension-less file playback in Firefox. Managed to get Firebug to show that the page has a audio/wav plugin loaded by changing the default mime-type for the server to application/octet-stream. So far no sound though.

In the process of doing this, I've also tried to get <embed>'s onerror attribute working so I can at least get some idea of what is going on. Unfortunately, as yet I've had no success.
