4.9 Audio subsystem
The CIARA Astro SN-6310 micro PC supports Intel High Definition Audio through a Realtek® ALC887-VD audio codec.
The Realtek® ALC887-VD based audio subsystem provides the following features :
• 8-channel (4 + 4) 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 95 dB
The board provides onboard audio headers and back panel connectors.
The onboard audio headers include the following :
• Front panel audio (a 10-1 pin header that provides headphone and mic in signals for front panel audio connectors)
• Internal mono speaker header (1 x 4-pin header)
Front panel headphone output is supported by a separate audio channel pair, allowing multi-streaming audio configurations such as
simultaneous 8-channel (4 + 4) 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 back panel audio connectors are configurable through the audio device drivers.
Audio software and drivers are available from http://www.asus.com/us/supportonly/H110T/HelpDesk_Download/ or from your
private CIARA Website.
