Alsa/Sound/ in 10.04 --> SOLVED

[zongo saiba]

Guys, 

Finally got my external speakers working and most of all, headsets are
working with muted internal speakers. 

I am posting here so if you have the same sound card and codec as me,
you can these settings and should be sorted. 

Type this in terminal --> $ cat /proc/asound/card0/codec#* | grep Codec.
If the result is as follow: 
Codec: Conexant CX20582 (Pebble)
Codec: Intel G45 DEVCTG

Modify this file /etc/modprobe.d/alsa-base.conf and add this line at the
end: 
options snd-hda-intel model="olpc-xo-1_5"

Reboot and voila. you should be sorted with external speakers and most
of all with headsets and muted internal speakers when the jack is in
use. 

Ubuntu v10.0.4
Alsa v1.0.23

Hope this help some of you guys because I know sound is just a nightmare
in Linux and I have been searching for a long time. I know that going
without external speakers or headset is not an option (was not for me).

Kind Regards

zongo
