Product Description

1.8 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.
