Audio Subsystem
The board supports Intel High Definition Audio through a Realtek ALC662-VC audio
codec.
The Realtek ALC662-VC-based audio subsystem provides the following features:
•
6-channel (5.1) audio with independent multi-streaming stereo
•
Advanced jack sense for the back panel audio connectors that enables the audio
codec to recognize the device that is connected to an audio port. The back panel
audio connectors are capable of retasking according to the user's definition, or can
be automatically switched depending on the recognized device type.
•
Stereo input and output via back panel connectors
•
Headphone and Mic in functions for front panel audio connectors
•
A signal-to-noise (S/N) ratio of 90 dB
The board provides onboard audio headers and back panel connectors.
The onboard audio headers include the following:
•
Front panel (a 2 x 5 pin header that provides headphone and mic in signals for
front panel audio connectors)
•
S/PDIF out header (1 x 4 pin header)
•
Internal mono speaker (1 x 2 pin header)
Front panel headphone output is supported by a separate audio channel pair, allowing
multi-streaming audio configurations such as simultaneous 6-channel (5.1) surround
sound playback and stereo audio conferencing (through speakers connected to the
back panel audio connectors and a headset connected to front panel audio
connectors).
The onboard internal mono speaker header allows connection to an internal, low-
power speaker for basic system sound capability. The subsystem is capable of driving
a speaker load of 8 Ω at 1 W (rms) or 4 Ω at 1.5 W (rms).
The onboard S/PDIF header allows connection to coaxial or optical adapters for digital
audio output.
The back panel audio connectors are configurable through the audio device drivers.
