lost my sound after installing updates

Please be sure all needed kernel modules are installed to make this check and install them:

So open a Terminal from the menu Applications → Accessories → Terminal and type:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-ubuntu-modules-$(uname -r)

give your user password when requested, you don't see nothing when you type it, then press enter.

Then reboot your pc.

Couldn't find package linux-ubuntu-modules-2.6.27-11-generic

this is what came up at the end.

after reboot still no sound

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo dpkg --configure -a

then to update and upgrade and also check pending or missing packages, still using terminal type:

sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove

Then reboot your pc and after reboot please reopen terminal and type:

sudo apt-get update
sudo apt-get install linux-ubuntu-modules-$(uname -r)

Then reboot your pc again.

Hope this helps
