Which is fine for single audio stream applications, but as OP mentioned,
his app has two different reasons to want audio.  One for the "telephone
ring" which he wants on speakers and one for voice audio which he wants
a different on a different device.

I'd be surprised if pulse has not provided applications that use pulse
directly the ability to do this kind of per-stream identification, but
until all such applications can be written to take advantage to that, it
would be nice/interesting in the meanwhile for pulse to provide multiple
ALSA "devices" for applications that need/can use multiple devices.
