// AudioChannels are used by:
// * HTMLMediaElement
// * AudioContext (WebAudio)
// When used, it has to throw an exception if the app tries to change the audio
// channel type without the permission (manifest file for B2G apps).
// The supported values are:
// * normal (default value)
// Automatically paused if "notification" or higher priority channel
// is played
// Use case: normal applications
// * content
// Automatically paused if "notification" or higher priority channel
// is played. Also paused if another app starts using "content"
// channel. Using this channel never affects applications using
// the "normal" channel.
// Use case: video/audio players
// * notification
// Automatically paused if "alarm" or higher priority channel is played.
// Use case: New email, incoming SMS
// * alarm
// Automatically paused if "telephony" or higher priority channel is
// played.
// User case: Alarm clock, calendar alarms
// * telephony
// Automatically paused if "ringer" or higher priority
// channel is played.
// Use case: dialer, voip
// * ringer
// Automatically paused if "publicnotification" or higher priority
// channel is played.
// Use case: dialer, voip
// * publicnotification
// Always plays in speaker, even when headphones are plugged in.
// Use case: Camera shutter sound.
