SND_VIA8233(4)	       FreeBSD Kernel Interfaces Manual		SND_VIA8233(4)

NAME
     snd_via8233 -- VIA	Technologies VT8233 bridge device driver

SYNOPSIS
     To	compile	this driver into the kernel, place the following lines in your
     kernel configuration file:

	   device sound
	   device snd_via8233

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   snd_via8233_load="YES"

DESCRIPTION
     The snd_via8233 bridge driver allows the generic audio driver, sound(4),
     to	attach to the VIA VT8233 audio devices.	 These audio chipsets are
     integrated	in the southbridge on many VIA based motherboards.

   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 fac-
			       ing weird interrupt problems or if the device
			       cannot generate interrupts at all.

HARDWARE
     The snd_via8233 driver supports the following audio chipsets:

     +o	 VIA VT8233
     +o	 VIA VT8233A
     +o	 VIA VT8233C
     +o	 VIA VT8235
     +o	 VIA VT8237
     +o	 VIA VT8251

SEE ALSO
     sound(4)

HISTORY
     The snd_via8233 device driver first appeared in FreeBSD 4.7.

AUTHORS
     This manual page was written by Joel Dahl <joel@FreeBSD.org>.

BUGS
     The snd_via8233 driver does not support S/PDIF.  There is partial support
     in	the code, so implementing it should be fairly easy if the right	hard-
     ware is available.
