Audio Header: F_AUDIO
The audio port includes two parts – the Front Audio and 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 , 6, 9 and 10 must be short connected, and then the
signal will be sent to the rear audio port.
S/PDIF Out Connector: SPDIF
The SPDIF_OUT output is capable of providing digital or 6 channel audio to
external speakers, or compressed AC3 data to an external Dolby digital decoder.
The motherboard is equipped with one bracket.
