cally turned off after the system enters suspend mode.

CD_IN, AUX_IN is Sony standard CD audio connector. It can be connected to a
CD-ROM drive through a CD audio cable.

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.
