Notes:
Since there are not independent Audio Mixer inputs for Pgm and Pst, Audio Mixer Channel Mapping on Pgm and Pst is
NOT independent of the other. Therefore, Audio Mixer Channel Mapping changes always affect BOTH Pgm and Pst
buses. This is consistent with other Audio Mixer parameters such as Stereo Mode, Gain, and Balance.
