Ubuntu 10.04 upgrade resulting in a no sound situation


After working happily a couple of months with Ubuntu 10.04 I installed a new kernel with the update feature. This resulted in not having any sound or volume controls. After reading a lot on internet articles  I found the following article... Comprehensive Sound Problem Solutions Guide v0.5e I followed the following commands that brought back sound to my notebook.

Getting the ALSA drivers from a *fresh* kernel

Sometimes, sound might be configured correctly, but for some reason or another (tinkering) it stops working. One way to go back to the old setup is to reinstall Ubuntu. However, this step is actually quite unnecessary since you are reinstalling everything because of one thing.

A faster way, is to just remove the problematic packages and reinstall them cleanly.

(1) Remove these packages
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils

(2) Reinstall those same packages
sudo apt-get install linux-sound-base alsa-base alsa-utils
VERY IMPORTANT NOTE: Ubuntu (GNOME) users have reported that packages 'gdm' and 'ubuntu-desktop' are removed after removing the linux-sound-base packages. If this happens, then do the following
sudo apt-get install gdm ubuntu-desktop

(3) Reboot
