(1) Remove the ALSA packages. From a terminal:
Code:
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
(2) Reinstall the same packages
Code:
sudo apt-get install linux-sound-base alsa-base alsa-utils
Packages gdm and ubuntu-desktop are also removed in this process if you are using Gnome. They need to be reinstalled:
Code:
sudo apt-get install gdm ubuntu-desktop
If you are using xubuntu this will also happen to you
Code:
sudo apt-get install gdm xubuntu-desktop
(3) Reboot.
If you needed to edit your /etc/modprobe.d/alsa-base file you may not have to with the updated driver but if you still do the file in Jaunty is /etc/modprobe.d/alsa-base.conf. This is to conform to configuration file naming conventions.
Then follow the guide. let me know how this works out for you.
Nope, this did not help.
I had sound after the installation of Jaunty but weeks later after a reboot caused by an Amarok crash my sound diasappeared completly! I tested the hardware by using a 9.10 LiveCD and there was sound, so now i want my sound back on Jaunty!
Here the logs of alsa-info.sh on 9.04 w/o sound:

using the liveCD from 9.10 i have sound again:
