The use case I have in mind is a vision impaired/blind user using a screen reader. The screen reader wants to duck all audio except the speech synthesizer, such that the user can more easily hear it. In addition, the user may want the audio for certain roles corked when there is an incoming VOIP call.

It can't do that right now, but the functionality could easily be added. 
It would only need an
additional parameter duck_roles, so that cork_roles would be corked 
while duck_roles would
only be ducked. I can implement it if this is needed.
