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.
