Override default audio sink from audio policy. When override is on, it is TvInputService's responsibility to adjust to audio configuration change (for example, when the audio sink becomes unavailable or more desirable audio sink is detected).
param
audioType one of AudioManager.DEVICE_* values. When it's * DEVICE_NONE, override becomes off.
param
audioAddress audio address of the overriding device.
