1. A method for audio processing, using a processor or circuit within a communication device, comprising:

  • determining, for a combined output audio signal that includes a plurality of component audio signals, again component audio signals;

    determining a total gain of the combined output audio signal as a sum of the determined gains of the plurality of component audio signals in response to detecting an off-hook state of the communication device;

    comparing the total gain to a predefined saturation threshold;

    implementing a volume control algorithm to limit the total gain when the total gain exceeds the predefined saturation threshold, the volume control algorithm comprising;

    determining audio requirements for each of a plurality of audio processing devices in a downlink processing path of the communication device;

    determining a default mix signal gain, a downlink gain adjustment, and a calibration gain based on the determined audio requirements; and

    calculating a mixed gain for the downlink processing path based on the determined default mix signal gain, the downlink gain adjustment and the calibration gain; and

    adjusting the total gain based on the mixed gain.
