Manual Pages  — SND_ATIIXP

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.

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.
