AIR Desktop - Audio Device Manager ActionScript API
The Audio Device Manager ActionScript API was added in Flash Player 27. This functionality is now enabled in AIR starting from AIR 28 for
Desktop only. This API provides the functionality of selecting audio output devices. AIR app developer should build their own UI to list the
available audio devices in a system and select the device for playback.
