I'm revisiting an unresolved bug report I opened several months ago: bug 
# 0003468
The bug still exists as of ALSA v1.0.15 (Ubuntu 8.04).

A quick recap:

The following line in patch_realtek.c is my machine:

SND_PCI_QUIRK(0x17aa, 0x2066, "Lenovo", ALC861VD_LENOVO),

If I edit this line as follows, I get sound:

SND_PCI_QUIRK(0x17aa, 0x2066, "Lenovo" ALC861VD_3ST),

(or I can just pass model=3stack to get sound).

Inserting headphones doesn't mute the speakers or power the headphones.  
But I can manually unmute the headphones via alsamixer (but speakers are 
still not muted).

I do see that the special keyboard keys for speaker mute, volume up and 
volume down are working correctly; but I don't know if this is something 
ALSA is responsible for, or X, or Ubuntu.  So if this is ALSA, thanks!

Anything more I can do to help resolve this?
