snd_atiixp — ATI IXP bridge device driver
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"
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.
The snd_atiixp driver supports the following audio chipsets: · ATI IXP 200 · ATI IXP 300 · ATI IXP 400
The snd_atiixp device driver first appeared in FreeBSD 6.1.

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.
