nVidia nForce2 sound

Hello!

My sound has dissapeared after pcm was removed. I've change pcm with 
'sound', but it does not help.
Today I decide to spend my time and to get back my sound.
But I have no success.

pciconf -l -v:
...
pcm0_at_pci0:6:0:  class=0x040100 card=0x10011695 chip=0x006a10de rev=0xa1 
hdr=0x00
     vendor   = 'NVIDIA Corporation'
     device   = 'nForce MCP-T Audio Codec Interface'
     class    = multimedia
     subclass = audio
...

'kldload snd_driver' loads all drivers with the same error:
pcm0: <nVidia nForce2> port 0xb800-0xb87f,0xb400-0xb4ff mem 
0xeb001000-0xeb001fff irq 11 at device 6.0 on pci0
pcm0: [GIANT-LOCKED]
pcm0: cannot reset channel 0
pcm0: unable to initialize the card
device_attach: pcm0 attach returned 6

What's up?
