The onboard audio DEM DAC operates at an oversampling rate of 96f
at 1f
driving low impedance headphones. A pair of analog inputs are provided to enable external audio sources to make use
of the headphone output buffers.
Audio data from the decoder part of the SAA7826 can be routed as described in Sections 7.10.1.1 and 7.10.1.2.
