.Dd November 29, 2006 .Dt SND_ATIIXP 4 .Os .Sh NAME .Nm snd_atiixp .Nd "ATI IXP bridge device driver" .Sh SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: d -ragged -offset indent .Cd "device sound" .Cd "device snd_atiixp" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent snd_atiixp_load="YES" .Ed .Sh DESCRIPTION The .Nm bridge driver allows the generic audio driver, .Xr sound 4 , to attach to ATI IXP audio devices. This driver supports 16bit playback and recording, and 32bit native playback and recording. .Ss Runtime Configuration The following .Xr sysctl 8 variables are available in addition to those available to all .Xr sound 4 devices: l -tag -width ".Va dev.pcm.%d.polling" -offset indent t Va dev.pcm.%d.polling Experimental polling mode, where the driver operates by querying the device state on each tick using .Xr 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. .Sh HARDWARE The .Nm driver supports the following audio chipsets:
p l -bullet -compact t ATI IXP 200 t ATI IXP 300 t ATI IXP 400 .El .Sh SEE ALSO .Xr sound 4 .Sh HISTORY The .Nm device driver first appeared in .Fx 6.1 . .Sh AUTHORS This manual page was written by .An Joel Dahl Aq joel@FreeBSD.org . .Sh BUGS The .Nm driver does not support S/PDIF, but implementing it should be fairly easy if the right hardware is available.
p 32bit native recording is broken on some hardware.
