SND_VIA8233(4) 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 mother- boards. 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 de- vice 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 sup- port in the code, so implementing it should be fairly easy if the right hardware is available. FreeBSD 13.2 November 29, 2006 SND_VIA8233(4)
