I've found a way to 'handle' the bug, and make changes as I wished, and have my sound back.
1 - To access the control-center.
# sudo gnome-control-center
There you make the changes, and your user stills affected.
2 - To have the sound back...
# sudo apt-get install dkms
#sudo reboot
After reboot the sound must be back.
This worked... Hope help the other eleven people with the same problem.
