The HD-audio driver can guess the right connection judging from these default configuration values. However – some codec-support codes, such as patch_analog.c, don’t support the automatic probing (yet as of 2.6.28). And, BIOS is often, yes, pretty often broken. It sets up wrong values and screws up the driver.

A part of the 12 problem is broken BIOS, and the rest is the driver implementation. 13 This document explains the brief trouble-shooting and debugging 14 methods for the HD-audio hardware. 15 16 The HD-audio component consists of two parts: the controller chip and 17 the codec chips on the HD-audio bus.

It only describes the standard way to write a PCI sound driver on ALSA. If you are already familiar with the older ALSA ver.0.5.x API, you can check the drivers such as sound/pci/es1938.c or sound/pci/maestro3.c which have also almost the same code-base in the ALSA 0.5.x tree, so you can compare the differences.

HD-audio is the new standard on-board audio component on modern PCs after AC97. Although Linux has been supporting HD-audio since long time ago, there are often problems with new machines. A part of the problem is broken BIOS, and the rest is the driver implementation. This document explains the brief trouble-shooting and debugging

alsa-driver alsa-driver contains the ALSA components that run in kernel space (e.g. all the modules). It also contains a few user-space components, including the alsasound startup script and a set of ALSA headers. This package is now obsolete. The kernel development continues in the standard linux kernel tree [2].
