1.8.2 Audio Connectors and Headers

The board contains an audio connector on the back panel and audio headers on the

component side of the board.

• Back panel audio connector:

⎯ Line out

• S/PDIF header:

⎯ 3-pin header

• Front panel audio header (supports both AC ’97 and HD Audio):

⎯ 10-pin header (for headphones/mic)

• Internal mono speaker header:

⎯ 2-pin header

⎯ Supports a 1.5 W/8 Ω speaker

The front/back panel audio connectors are configurable through the audio device

drivers.

The audio stream for the line-out port is routed according to these dependencies:

• By default the audio stream is down-mixed to mono and amplified for an internal

mono speaker.

• A connection is detected at the rear line-out port, the audio stream goes to the

rear line-out port and the internal mono speaker is disabled.

NOTE

BIOS status and error beep codes can be heard through an internal speaker if the

internal speaker is connected to the internal mono speaker header.
