Relation with virtual audio destinations on mobile devices.

[chrisguttandin]

I wonder if this API somehow implies that audio will be played out on one of the virtual audio destinations on mobile devices. Sorry in case there is an official term for those destinations/groupings which I'm not aware of.

Android does for example currently allow to control the following four volume levels separately.

Media volume: Music, videos, games, and other media
Call volume: Volume of the other person during a call
Ring & notification volume: Phone calls, and notifications
Alarm volume

Would an AudioSession with a type of 'playback' imply that it will be played with the "Media volume"? Or would an AudioSession with a type of 'transient' imply that it will be played with the "Ring & notification volume"?

How would one play something with the "Call volume"? I imagine this would be useful for WebRTC calls. Similarly, how would one play something with the "Ring & notification volume"? I imagine this would be useful for a "notify me when the live stream starts" feature.

As far as I know everything coming from the browser is currently played with the "Media volume".
