Publisher’s description

This paper presents programming guidelines and a set of reference pages for the Intel High Definition (HD) Audio device driver interface (DDI). Audio and modem drivers call the routines in this DDI to manage hardware codecs that are attached to an HD Audio bus interface controller. In the Microsoft Windows codenamed "Longhorn" operating system, Microsoft intends to provide both a Universal Audio Architecture (UAA) class driver for a UAA-compliant HD Audio codec and a bus driver for the HD Audio controller.
