HD Audio support in the 1xx3 improved through the chipset's life with several revisions. The DD and CC versions of the chipset both added full 7.1 HD-audio support to the chipset. The 1073 players all built on a common SDK (firmware+OS) provided by Realtek. This meant that they were all essentially similar in performance and interface.
Intel High Definition Audio. Realtek ALC 882 HD Audio Codec. Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard. [1]
AC'97 defines a high-quality, 16- or 24- bit audio architecture with 5.1 surround sound support for the PC. AC'97 supports a 96 kHz sampling rate at 24-bit stereo resolution and a 48 kHz sampling rate at 24-bit stereo resolution for multichannel recording and playback. Integrated audio is implemented with the AC'97 Codec on the motherboard, a ...
