AFE module sits right at the other end of cpu where the codec/audio devices are connected. AFE provides abstraced interfaces to both hardware and virtual devices. Each AFE tx/rx port can be configured to connect to one of the hardware devices like codec, hdmi, slimbus, i2s and so on. AFE services include starting, stopping, and if needed, any configurations of the ports.
