The audio connector supports HD audio
standard and provides two kinds of audio
output choices: the Front Audio, the Rear
Audio. The front Audio supports re-tasking
function.
Note:
In order to utilize the front audio
header, your chassis must have front
audio connector. Also please make
sure the pin assignment on the cable
is the same as the pin assignment on
the mainboard header. To find out if
the chassis you are buying supports a
front audio connector, please contract
your dealer.
