Dear experts,

I am trying to understand whether or not Android handles the phone
conversation's audio stream or it is done outside Android's framework.
Specifically, if, for example, Android controls a cellular processor
that provides PCM interface for voice conversation and there is a need
to send audio over Bluetooth instead of using mic/speakers, how this
is handled?
There are two ways here to the best of my understanding:

1. Route PCM from cellular to audio port on Android CPU, then let
Android receive the stream and send it to BT stack for processing and
eventually pushing to BT hardware over HCI
2. Have Android control a HW switch that will route PCM directly to BT
HW using direct PCM interface

Which one applies? Is there a preferable way (best usage of resources
provided by Android)?

Your advice is very much appreciated

Thanks,
Michael
