I have a little problem, I touched something related to alsa on the software center, becuase there was a corrupted package that I tried to install (alsa-conexant... or something like this)

After removing it, the sound stop working, now at the taskbar it does not show the sound notification.

I can acess sound config, via "Sound" in Applications, but when I try to choose a Hardware, the list is in blank, there are no devices.

You may have removed a package or two too many. Make sure the ubuntu-desktop package is installed, and if not, install it.

sudo apt-get install ubuntu-desktop

That it does not work, I can not select any hardware on sound config. – jochy2525 Aug 23 '11 at 16:02
Let's see the APT history log. 'tail -n 50 /var/log/apt/history.log' The output of that command should show what was installed and uninstalled recently. – mikewhatever Aug 23 '11 at 17:40
