Why do I still get giant gray 'X's instead of an audio player, even with the correct MIME type for my Ogg Vorbis file, whether coded in the audio tag or as a source?

Question

I uploaded Saturnalia.ogg to my site and used the audio tag to try to display it on my test page. I'd love to ditch the ultra-slow Flash players I currently use, but I don't want to leave most of my site's users wondering what the files sound like, where they are, and why are there giant gray Xs ruining my layout. The audio files work fine in Safari and Opera, and IE uses the correct fallback text. I've tried both coding the file into the audio tag and into source tags. I've set controls="controls" and tried both type="audio/ogg" and type="audio/vorbis". I've tried with and without autoplay.
According to Mozilla, audio tags are supported, but I'm not seeing any of that support on my site.

Answer 1

Where are you seeing that?
Earlier:
<audio src="dsh.ogg" controls="controls" type="audio/ogg">Your browser does not support the HTML5 audio tag.</audio>
Now:
[<object type="application/x-java-applet" width="580" height="15px" controls="controls">
<param name="archive" value="cortado.jar" />
<param name="code" value="com.fluendo.player.Cortado.class" />
<param name="url" value="http://desolosubhumus.webs.com/dsh.ogg" />
You need to install Java to play this file.
</object>]<br />
<audio src="dsh.ogg" type="audio/ogg">
You need to install Java to play this file.
</audio>
*p tags removed for readability
I know the audio tag should open before the object tag opens and close after the object tag closes, and that I shouldn't need duplicate fallback text, but it wouldn't show up that way. The way I have it set up now finally works on Firefox, IE (plays, not fallback text), Opera, Safari, and Chrome. I'm still trying to tweak the code to make it more standard (audio tags in the proper places), to clean it up so it's not such a huge chunk, and to see if I can get the applet to stay visible (which may not be possible, as the only way I've made it work is as a Cortado VIDEO instead of a purely audio file), and to make it stop autoplaying instead of playing when the user chooses play. Perhaps a Kate stream for track labels and a play button image set directly behind the applet when the play button actually is.
