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
