NAME

       snd_atiixp — ATI IXP bridge device driver

SYNOPSIS

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

             device sound
             device snd_atiixp

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

             snd_atiixp_load="YES"

DESCRIPTION

       The  snd_atiixp  bridge  driver  allows  the  generic  audio driver, sound(4), to attach to ATI IXP audio
       devices.  This driver supports 16bit playback and recording, and 32bit native playback and recording.

   Runtime Configuration
       The following sysctl(8) variables are available in addition to those available to all sound(4) devices:

             dev.pcm.%d.polling  Experimental polling mode, where the driver operates  by  querying  the  device
                                 state  on  each tick using callout(9).  Polling is disabled by default.  Do not
                                 enable it unless you are facing weird  interrupt  problems  or  if  the  device
                                 cannot generate interrupts at all.

HARDWARE

       The snd_atiixp driver supports the following audio chipsets:

       •   ATI IXP 200
       •   ATI IXP 300
       •   ATI IXP 400

BUGS

       The  snd_atiixp  driver  does  not support S/PDIF, but implementing it should be fairly easy if the right
       hardware is available.

       32bit native recording is broken on some hardware.
