This jumper is used to set enable or disable CNR audio function. The default state
for J9 is set to disable (Pin1 & Pin2 together), then you cannot use the CNR audio
and onboard audio is avaliable. If you want to use CNR audio function, set J9 to
enable (Pin2 & Pin3 together).

The USB header is available for additional USB port if the USB ports on the rear
panel are inadequate. Compared to traditional USB 1.1 with the speed of 12Mbps,
USB 2.0 has a fancy speed up to 480Mbps, which allows faster Internet connection,
interactive gaming, and simutaneous running of high-speed peripherals.

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 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 motherboard is equipped with the Realtek ALC655 chip, which provides sup-
port for 6-Channel audio output, including 2 front, 2 rear, 1 center and 1 subwoofer
channel. ALC655 allows the board to attach 4 or 6 speakers for a better surround
sound effect. To apply this function, you have to install the audio driver in utility CD
as well as an audio application supporting 5.1 Channel. Picture bellow repre-
sents the standard location of all speakers in 5.1 Channel sound track.
