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.
