1.9 Audio Subsystem
The board supports the following audio options:
•
An audio subsystem based on the Realtek ALC202A codec providing:
Signal-to-noise ratio
≥
90 dB
Wake event support (driver dependent)
Mic in pre-amp that supports dynamic, condenser, and electret microphones
•
An optional Flex 6 audio subsystem based on the Analog Devices AD1985 codec providing:
Advanced jack sense with Auto Topology Switching that enables the audio codec to
recognize what device is connected to an audio port and alerts the user if the wrong type of
device has been connected
Split digital/analog architecture for improved S/N (signal-to-noise) ratio:
> 94 dB
1.9.1

1.9.2
Audio Connectors
The board contains 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)
•
Auxiliary line in (a 1
x
4-pin ATAPI-style connector for the left and right channel signals of an
internal audio device to the audio subsystem)
•
ATAPI CD-ROM (a 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-pin connector that provides S/PDIF output signals)
The functions of the back panel audio connectors are dependent on which subsystem is present.
Refer to Section 1.9.3 for back panel audio configuration for the Realtek ALC202A audio
subsystem.
