Pin Configuration Guidelines for High Definition Audio Devices

June 17, 2013 Version 1.2

Abstract

This document provides information about Intel High Definition Audio (HD Audio) devices and drivers for the Microsoft® Windows® family of operating systems. It provides guidelines for system integrators (OEMs and ODMs) and BIOS developers for programming default values for the Pin Configuration registers in an HD Audio codec. An HD Audio codec that follows the Microsoft Universal Audio Architecture (UAA) hardware guidelines can rely entirely on the system-supplied driver support in Windows. A primary component of this driver support is the UAA HD Audio class driver, which uses the data in the Configuration Default registers to identify the individual audio devices in the codec and to make them available to the operating system and applications.

This information applies for the following operating systems:
Microsoft Windows Vista™
Microsoft Windows Server™ 2003
Microsoft Windows XP
Microsoft Windows 2000

Future versions of this preview information will be provided in the Windows Driver Kit.

The current version of this paper is maintained on the WHDC Web site at:
