I'm attempting to embed an HTML5 audio element pointing to MP3 or OGG data served by a PHP file . When I view the page in Safari, the controls appear, but the UI says "Live Broadcast." When I click play, the audio starts as expected. Once it ends, however, I can't start it playing again by clicking play. Even using the JS API on the audio element and setting currentTime to 0 fails with an index error exception.
I suspected the headers from the PHP script were the problem, particularly missing a content length. But that's not the case. The response headers include a proper Content- Length to indicate the audio has finite size. Furthermore, everything works as expected in Firefox 3.5+. I can click play on the audio element multiple times to hear the sound replay.
If I remove the PHP script from the equation and serve up a static copy of the MP3 file, everything works fine in Safari.
Does this mean Safari is treating audio src URLs with query parameters differently than URLs that don't have them? Anyone have any luck getting this to work?
My simple example page is:
<!DOCTYPE html>
<html>
<head></head>
<body>
<audio controls autobuffer>
<source src="say.php?text=this%20is%20a%20test&format=.ogg" />
<source src="say.php?text=this%20is%20a%20test&format=.mp3" />
</audio>
</body>
</html>

I tried hard-coding the Accept-Ranges header into the script too, but no luck.
