Hello everybody

To begin excuse my approximative english, I'm french (but I speak better than my president don't worry)

I have a laptop, but I can't use any micro, neither the one which is integrated in the computer, nor the one I recently bought...
My configuration is the following :
Code:
cat /etc/lsb-release
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04.1 LTS"

lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.21

uname -a
Linux airis 2.6.32-24-generic #43-Ubuntu SMP Thu Sep 16 14:17:33 UTC 2010 i686 GNU/Linux
I first followed the french doc (in vain) so I tried the english one (how can I give you the link?

But
Code:
$ cat /proc/asound/card0/codec#* | grep Codec
return three results instead of one :
Codec: Realtek ALC268
Codec: LSI ID 1040
Codec: Nvidia MCP78 HDMI

The only one to be in the file /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz is ALC268 so I try this one :
Code:
$ sudo nano /etc/modprobe.d/alsa-base.conf
and then I add options snd-hda-intel model=auto in the last line.
