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:

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.
