ALSA
Introduction to ALSA
The Linux kernel now provides Advanced Linux Sound Architecture (ALSA) support by default. However, applications need to interface to that capability. The following six sections deal with the six separate components of ALSA: the libraries, the plugins, the utilities, the tools, the firmware and the OSS compatibility libraries.
Note on nVidia nForce 430
If you have nVidia HDA audio chips MCP51, MCP55, MCP65, or MCP67, nVidia recommends the hda-intel module for these chips. The ALSA driver code did not include support for these chips until 1.0.14rc1. ALSA-driver-1.0.14rc1 wasn't included in the kernel until the 2.6.20 series. If you don't want to use a prepatch version of the kernel and can't wait for sound, the following patch can be applied to the linux-2.6.19 source so the snd-hda-intel module will support these nVidia chips.
