4.3.2 Audio Modes
The PP audio handling consists of four audio states. In
these states the audio subsystem is configured for a
certain audio mode:
1. Idle state (not relevant for microphone
configuration)
2. Earpiece Mode (Handset Speaker)
3. Handsfree or Speakerphone Mode
4. Headset mode
Selection between the modes is done by API calls; see
document reference [1].
The Alert state is for tone playing and is entered
automatically when tones are played using the API
calls. The Alert state can originate from idle earpiece,
handsfree or headset state
.
