Adds "Analog PCM Volume" control with supported values 0 = 10dB,1 = 13dB,2 = 16dB and 3 = 19dB. The amplifier can operate either in Speaker Mode or Receiver Mode as configured by the user. Speaker Mode has four gain options to support maximum amplifier output amplitude for loud speaker application. Receiver Mode has further optimized noise performance while maintaining sufficient output to support phone receiver application. While configured in Receiver Mode, the analog PCM Volume control is disabled and the analog gain is fixed to 1dB.
