谢谢楼上的兄弟，其实我就是想知道这个889到底是885的改进呢还是简化版，呵呵。

7.1+2 Channel High-Performance HDA Codec with Content Protection
  
! J' l, T- U( U+ _General Description
: J6 T+ V9 o4 k$ z+ }; kThe ALC885 is a high-performance 7.1+2 Channel High Definition Audio Codec with advanced lossless content protection technology that protects pre-recorded content while still allowing full-rate audio enjoyment from DVD audio, Blu-ray DVD, or HD DVD discs.


The ALC885 provides ten DAC channels that simultaneously support 7.1 sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. Three stereo ADCs are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies simultaneously.

: v2 f) n: s& hAll analog IO are input and output capable, and headphone amplifiers are also integrated at each analog output. All analog IOs can be re-tasked according to user’s definitions, or automatically switched depending on the connected device type.


# n: M( g3 N* p* F4 RSupport for 16/20/24-bit S/PDIF input and output offers easy connection of PCs to high-quality consumer electronic products such as digital decoders and speakers. The series incorporates Realtek proprietary converter technology to achieve 106dB Signal-to-Noise ratio (SNR) playback quality and 101dB SNR recording quality, and is designed for Windows Vista premium desktop and laptop systems.
