Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::System::Window Mgmt, defect)

Description

[(inactive after 6/18) Alive Kuo [:alive]]

BrowserAudioChannel is the API wrapper of new audio channel API.
There would be an AudioChannelManager to gather all events from BrowserAudioChannel to decide competing result and control the instance.

The audio channel management API document: https://gist.github.com/evanxd/41d8e2d91c5201a42bfa
(discussed by Gaia and Gecko people)

We will implement the Gaia module without the Gecko API support, and the API doc is what we assume to do that.

When an app is created(`appcreated` event received) in app window manager[1], we do `audioChannelManager.register(app.browser.element)`[2] for managing its audio channel there[1].

And we do same thing for activity's audio channel management in activity window manager[2].
