Sound card problem

[umarc]

Folks:

I just installed FreeBSD 6.1 on an old Compaq Presario 1277 laptop, and I 
can't get sound to work. When I load the driver module, I get two clicks 
form the speaker, but then the following lined show up in dmesg:

pcm0: <VIA VT82C686A> port 0x1000-0x10ff,0x1834-0x1837,0x1830-0x1833 irq 
11 at device 7.5 on pci0
via: codec invalid
via: codec invalid
via: codec invalid
via: codec invalid
via: codec invalid
pcm0: ac97 codec invalid or not present (id == ffffffff)
device_attach: pcm0 attach returned 6

I'm using the snd_via82c686 driver, which used to work in previous 
versions of FreeBSD. Is there something I should be doing differently in 
6.1?
