[Android-development] Audio to Earpeice

[Jason H]

I had a peak at the Qt source on gitlab (assuming it's up to date) and it looks like it does not support Roles, or Android's Streams. They map pretty closely:

Android AudioManager 	: Qt Audio Role
STREAM_ACCESSIBILITY	: AccessibilityRole	
STREAM_ALARM		: AlarmRole	
STREAM_DTMF		: ** no match **
STREAM_MUSIC		: MusicRole	
STREAM_NOTIFICATION	: NotificationRole 	
STREAM_RING		: RingtoneRole	
STREAM_SYSTEM		: SonificationRole	
STREAM_VOICE_CALL	: VoiceCommunicationRole
** no match ** 		: VideoRole	
** no match ** 		: GameRole
** no match ** 		: UnknownRole

supportedAudioRoles should be: [AccessibilityRole, AlarmRole, MusicRole, NotificationRole, RingtoneRole, SonificationRole, VoiceCommunicationRole]

It should be an easy add... Would this have to wait until 5.13?
