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):
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.
