1. A method for muting zero level pulse code modulated (PCM) samples received as inputs to a digital to analog converter (DAC)
including a PCM input module and a mapping module, the method comprising:
monitoring a level of the PCM samples received as inputs to the PCM input module;
sensing consecutive zero level PCM samples from among the monitored input PCM samples; and
muting a PCM input to the mapper when only a single parameter has been sensed, the single parameter being a predetermined
number of consecutive zero level PCM samples.
