The machine is a Lenovo 3000 N100.

There are two methods I can choose to get sound working partially:

1.  Edit patch_realtek.c (near line 10971):
     from     SND_PCI_QUIRK(0x17aa, 0x2066, "Lenovo", ALC861VD_LENOVO)
     to         SND_PCI_QUIRK(0x17aa, 0x2066, "Lenovo", ALC861VD_3ST)


2.  Use modprobe snd-hda-intel model=3stack

I guess both methods accomplish the same thing.  I'm not saying I know 
the reason why this works, but I'd like to help find out why the 
ALC861VD_LENOVO quirk is not working on my machine.

Using this hack, I can hear sound from the speakers and headphones, yet 
headphones do not mute the speakers when pluged in.  I can record from 
either the built-in or external mic.  Is pluging in an external mic 
supposed to mute the internal mic?  (It doesn't).

Here is a pastbin using Kubuntu 7.10 with model=3stack:

Is there any information I could get from Vista to help?  I can dual boot.

Thanks,

Chris
