Hi,

Just wondering if anyone has any experience getting sound working for an 
nforce1 motherboard?

Seems I have the correct driver loaded and the device exists but no sound...

Some info:

# pciconf -vl

<snip>

none4 at pci0:5:0: class=0x040100 card=0x37301462 chip=0x01b010de rev=0xc2 
hdr=0x00
    vendor   = 'NVIDIA Corporation'
    device   = 'nForce MCP Audio Processing Unit (Dolby Digital)'
    class    = multimedia
    subclass = audio
pcm0 at pci0:6:0:  class=0x040100 card=0x37301462 chip=0x01b110de rev=0xc2 
hdr=0x00
    vendor   = 'NVIDIA Corporation'
    device   = 'nForce MCP Audio Codec Interface'
    class    = multimedia
    subclass = audio


kldload snd_ich.ko

Any help appreciated :)

Cheers,
