SND_CSA(4)

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.
