The newer players have some changed hardware, but most importantly the line out now appears to be routed through the stereo switch instead of being hardwired directly off the DAC. Disable muting the headphone amp, enable switching the stereo switch, and rename some of the GPIOs to be more generic since the DAC, headphone amp, and stereo switch all appear to have changed.
