I am not at all familiar with the hardware design of phones, so I want to be very clear in my understanding.
Are you saying that the electrical signals from the microphone and to the speakers pass through the baseband chip before/after going to the main chip on the phone? Or that the baseband chip has separate access to the microphone and speakers?
