3.18 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 an 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.
