Hm.  I confess I don't use my DF machine for multimedia, but I do load the
sound driver at boot, well, just because I can :o)

~# kldstat
Id Refs Address    Size     Name
 1    7 0xc0100000 321d08   kernel
 2    1 0xc0422000 5020     snd_via8233.ko
 3    2 0xc0428000 1c590    snd_pcm.ko

# pciconf -lv (irrelevant output snipped)
pcm0 at pci0:17:5: class=0x040100 card=0x18411019 chip=0x30591106 rev=0x50 hdr=0x00
    vendor   = 'VIA Technologies Inc'
    device   = 'VT8233/33A/8235/8237/8251 AC97 Enhanced Audio Controller - the
8251 controller is different'
    class    = multimedia
    subclass = audio

The trouble I see on my DF machine is that userland apps like
gnome-volume-control complain about 'unknown mixer device'.

Do you see any errors when you load snd_via8233 from a command prompt?
