Product Description

1.11 Audio Subsystem

The boards support the Intel High Definition audio subsystem based on the Realtek ALC880 or the

Realtek ALC860 audio 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.

1.11.1

Audio Subsystem Software

Audio software and drivers are available from Intel’s World Wide Web site.

For information about

Refer to

Obtaining audio software and drivers

Section 1.4, page 19

1.11.2

Audio Connectors

The boards contain audio connectors 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)

The functions of the back panel audio connectors are dependent on which subsystem is present.

The 8-channel (7.1) audio subsystem is described in Section 1.11.3; the 6-channel (5.1) audio

subsystem is described in Section 1.11.4.
