Sound API

The Sound API provides functions to control the volume level for several sound types and to check whether a specified sound device type is connected.

You can get the maximum volume level for system, notifications, alarm, media and so on. Also, you can change or get the current volume level.

For more information on the Sound features, see Audio Management Guide.
