I feel this method has a gap: Since the voice data from cell modem bypass PA in such a system, will the dialer app create the sink-input/source-output stream tagged as 'voice' or 'phone' for PA? If the phone streams do not appear in PA, PA cannot know the time to switch profile by checking the stream's media role. Please correct me if I misunderstand something.
