Audio Interface: F_AUDIO
The audio interface provides two kinds of audio output choices: the Front Audio,
the Rear Audio. Their priority is sequenced from high to low (Front Audio to Rear
Audio). If headphones are plugged into the front panel of the chassis (using the
Front Audio), then the Speaker Out (Rear Audio) on the rear panel will not work.
If you do not want to use the Front Audio, pin 5 and 6, pin9 and 10 must be
unlocked, and then the signal will be sent to the rear audio port.
S/PDIF Out Connector: SPD_OUT
The S/PDIF out connector is capable of providing digital audio to external speak-
ers or compressed AC3 data to an external Dolby digital decoder.
