Comment 94 for bug 131133

http://ubuntuforums.org/showthread.php?t=564581&highlight=82801h

here is a solution for that chipset, that worked on Tribe 4 on a D630 for _Doc_, and worked on gusty beta on a D830 for me :

sudo apt-get install module-assistant
sudo m-a update
sudo m-a prepare
sudo m-a a-i alsa

+reboot ( or restart alsa components)

I had compiled Alsa version 1.0.15rc1 as described on https://wiki.ubuntu.com/LaptopTestingTeam/DellLatitudeD830 , but it didn't work.

maybe it's necessary to have that version of Alsa, and to do that trick to make it work.....

At last i have sound !!!
