SND_VIA8233(4) BSD 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 in- tegrated 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 op- erates 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. BSD November 29, 2006 BSD
