The SPDIF out connector is capable of providing digital
audio to external speakers or compressed AC3 data to
an external Dolby digital decoder.
Front 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, pin
9 and 10 must be SHORT, and then the signal
will be sent to the rear audio port.

The connectors connect to the chassis security switch on the case. The system
can detect the chasis intrusion through the status of this connector. If the con-
nector has been closed once, the system will send a message. To utilize this
function, set “Intruder# Detection” to “Enabled” in the “Power Management Setup”
section of the CMOS Setup. Save and exit, then boot the operating system once
to make sure this function takes effect.
