This may help some Lenovo user :

with a laptop model : Lenovo 3000 C200 8922AZG

Using headphone, I was obliged to mute manually the speakers output
(with gnome volume manager)

Adding this line in /etc/modprobe.d/alsa-base:

"options snd-hda-intel model=lenovo"

fixes the problem : when I plug headphones, speaker are automatically off 
(the box headphone in the volume manager has to be checked whatever output you use)

Additionnal information of my current install :

$uname -a
Linux NEANT 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux
