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.
