Audio Connector: F_AUDIO
The audio interface provides two kinds of au-
dio 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 Line-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 short, and then the signal
will be sent to the rear audio port.
Besides four USB ports on the rear panel, the
series of motherboards also have two or three
10-pin connectors on board which may connect
to front panel USB cable(optional) to provide
additional four USB ports.
