43 This diagram shows a simple smart phone audio subsystem. It supports Bluetooth,
46 supports 6 back end (BE) DAIs. Each FE PCM can digitally route audio data to any
47 of the BE DAIs. The FE PCM devices can also route audio to more than 1 BE DAI.
55 and audio continues playing on the speakers.
89 The audio driver processes this as follows :-
93 2) Machine driver OR audio HAL disables the Headset path.
98 4) Machine driver or audio HAL enables the speaker path.
