Intel Desktop Board D865GVHZ Technical Product Specification

1.9 Audio Subsystem

The board supports the following audio options:
• An audio subsystem based on the Realtek ALC202A codec that provides:

  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 that

provides:
 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

1.9.2 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 (a 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.
Section 1.9.3 describes back panel audio configuration for the Realtek ALC202A audio subsystem.
Section 1.9.4 describes back panel audio configuration for the Intel

Flex 6 audio subsystem.
