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 sounddevice snd_atiixp
Alternatively, to load the driver as a module at boot time, place the
following line in
loader.conf5:

DESCRIPTION
The
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.
