Which driver for SIS sound controller ?

[edward]

Hi all,
I have installed 5.3 release and KDE 3.3 on a NEC machine (i386) with an
integrated sound chip. When I start KDE, i get the following error message :
Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (No such file or directory)
The sound server will continue, using the null output device

I assume I need to load a kernel module (handbook wise). The integrated
sound chip on my motherboard is labeled "Silicon Integrated Systems (SIS)
sound controller" and, under Linux, the driver is snd-intel8x0
It doesn't seem to appear in the hardware compatibility list for 5.3
release, although it seems to be a rather common component.
Does anyone know which FreeBSD driver I should use and if I'm on the right
track ?
Thanks,
Edward
