I don't actually play the audio, I just land on the page.  The audio device 
goes to state PREPARED.  It remains in that state until I navigate away from 
the web page.

In the bug that you referred to, the state went to RUNNING.  The situation I 
am encountering seems different.  Maybe it is intended that the state should go 
to PREPARED, but the effect is that no other program can use the audio device, 
even one that actually has something to play.  The application running webkit 
will never actually play anything, so it would be unfortunate if there weren't 
a way to prevent webkit from monopolizing a device that it only thinks it 
might use.
