1.9 Audio Subsystem

The boards support the Intel High Definition audio subsystem based on the Realtek ALC860
codec. The audio subsystem supports the following features:
•
Advanced jack sense (front and rear panel) that enables the audio codec to recognize the
device that is connected to an audio port. All jacks are capable of retasking according to user's
definition, or can be automatically switched depending on the recognized device type.
•
Stereo input and output for all jacks.
•
A signal-to-noise (S/N) ratio of 90 dB.
INTEGRATOR'S NOTE
For the front panel jack sensing and automatic retasking feature to function, a front panel
daughter card that is designed for Intel High Definition Audio must be used. Otherwise, an AC '97
style audio front panel connector will be assumed and the Line Out and Mic In functions will be
permanent.

1.9.2 Audio Connectors

The boards contain audio connector on both the back panel and the component side of the board.
The component-side audio connectors include the following:
•
Front panel audio (a 2 x 5-pin connector that provides mic in and line out signals for front
panel audio connectors)
•
ATAPI CD-ROM (an optional 1 x 4-pin ATAPI-style connector for connecting an internal
ATAPI CD-ROM drive to the audio mixer)
•
S/PDIF (an optional 1 x 3 connector that provides S/PDIF output signals)
The functions of the back panel audio connectors are dependent on which subsystem is present.
