    PCM is the raw digital data of audio before converting into a file format, such as WAV, MP3, FLAC, etc and for Home Theater, such as 3.1, 5.1, 7.1, etc.  Basically, keeping your audio PCM at the cable-box and TV allows your soundbar to process the PCM data.

    Cable-boxes and TV sets do not process audio well so just leave it PCM and allow something designed to process audio process the audio.
