Audio Controller: Cirrus Logic|CS 4614/22/24 [CrystalClear]
The Crystal 4614 is not supported by the 2.2.x Linux kernels, although it is supported by the ALSA-Project drivers which are freely available for download from
http://www.alsa-project.org. You will need to install the latest versions of the drivers, libraries, and utilities found at this site. You can find the documentation/mini "howto" at
http://www.alsa-project.org/~valentyn/Alsa-sound-mini-HOWTO.htm. After ALSA is installed you will need to run "modprobe snd-card-cs461x", and then unmute and turn up the volume of the sound devices by issuing the following commands:
amixer set Master 100 unmute
amixer set PCM 100 unmute
In order to be compatible with the standard OSS sound drivers, I also recommend running "modprobe snd-pcm-oss" to set your audio device to /dev/audio
