In the smartphone scenario, there are some streams that are not handled
by the processor. This is typically the case if you have a phone module
wired to the bluetooth pcm. Today's smartphones even have a hardware
routing chip capable of mixing and routing streams. Example inputs are
radio and phone module, example outputs are speaker, loudspeaker,
earphone and bluetooth.

The audio router should be able to take these streams into account.
Having a separate global audio routing would be very flexible. This
would allow to fit a large number of hardware platforms.

Last, there should be a way to distinguish between different streams
natures : for example an alert should not interfere with a voip call .

BR,
