3.13 Audio
Audio input and output functions can be accessed via a 2x5 pin connector (JST B10B-PHDSSLFSN,
mating connector: PHDR-10VS). There are two ways to use this connector. Default functionality is the
familiar audio in, audio out, and microphone. OS dependent device drivers can switch these signals to
support a 5.1 output; thus in this mode no audio input signals are available.
Signals "SPDIFI" and "SPDIFO" provide digital input and output. If a transformation to a coaxial or optical
connector is necessary this must be performed externally.
