Contrived? It's an example of good behaviour by an existing phone, so it's a 
real world example.

Several people have asked about unusual audio routing configurations for 
specific applications. If another app changes the mixer settings then these 
apps will not work correctly, so it would be beneficial for them to handle 
this gracefully. To do this they need notification of the change in mixer 
setting. 

Changing the entire mixer scenario strikes me as being too coarse a control, 
but I haven't heard of any better proposals for abstraction.
