Supported routing paths

Each audio type (such as sound effects, ringtones, and so on) uses a priority system to determine which of the available devices to route audio to.

The following table lists supported routing paths for each audio type. The audio types are listed in descending order of their routing priority. That is, AUDIO_TYPE_SOUND_EFFECT has a higher routing priority than AUDIO_TYPE_RINGTONE, which itself has a higher routing priority than AUDIO_TYPE_VOICE, and so on.
