[webkit-dev] Webkit seizes sound device

[Jeffrey Barish]

When I visit a web page that wants to play a sound, webkit opens the sound 
device and never lets go of it until the application exits.  I would like for 
webkit not to open the sound device (and ignore the play request, obviously).  
Is there a way to tell webkit globally that it should ignore all sounds and 
never, ever open the sound device?
