ALSA driver configuration files
This package contains various configuration files for the ALSA drivers. . For ALSA to work on a system with a given sound card, there must be an ALSA driver for that card in the kernel. Linux 2.6 as shipped in linux-image packages contains ALSA drivers for all supported sound cards in the form of loadable modules. A custom alsa-modules package can be built from the sources in the alsa-source package using the m-a utility (included in the module-assistant package). Please read the README.Debian file for more information about loading and building modules. . ALSA is the Advanced Linux Sound Architecture.
