Loading sound drivers

[af300wsm at gmail.com]

Hi,

My motherboard, an ASUS K8V-X, has a generic type sound chip on board,  
according to ASUS' specifications, it is an AD1980 chipset. The hardware  
notes, linked from the handbook, does not list this chipset but does list  
several Intel type HDA chipsets including one AD1981 chipset. Never the  
less, using the handbook instructions I loaded the meta sound driver and my  
chipset was identified as a via8233 chipset. The meta driver loaded many  
drivers into the kernel, but through trial and error I've discovered that  
only sound.ko and snd_via8233.ko need to be loaded. So, I put these two  
lines into /boot/loader.conf:

sound="YES"
snd_via8233="YES"

However, these two modules do not load on bootup. Why? How do I fix this?

Thanks,
Andy
