NAME

snd_csa — Crystal Semiconductor CS461x/462x/4280 PCI bridge device driver

SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

device sound
device snd_csa

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

snd_csa_load="YES"

DESCRIPTION

The snd_csa bridge driver allows the generic audio driver sound(4) to attach to Crystal Semiconductor CS461x/462x/4280 based sound cards.

HARDWARE

The snd_csa driver supports the following sound cards:

Crystal Semiconductor CS4280
Crystal Semiconductor CS4610
Crystal Semiconductor CS4611
Crystal Semiconductor CS4614
Crystal Semiconductor CS4615
Crystal Semiconductor CS4622
Crystal Semiconductor CS4624
Crystal Semiconductor CS4630
Genius Soundmaker 128 Value
Hercules Game Theatre XP
Turtle Beach Santa Cruz

Some onboard CS4610 chips are accompanied by the CS423x ISA codec instead of the CS4297 AC97 codec. Such configurations are not supported by the snd_csa driver yet.

HISTORY

The snd_csa device driver first appeared in FreeBSD 4.0.
