Sound problems after Ubuntu 12.04 upgrade

I have managed to make my first successful migration since I am using Ubuntu. Of course successful is a relative term. I had a few issue, among them was my sound. I had no sound from my OS or Rhythmbox. I did have sound from movies (probably due to the fact that my VLC drivers/codecs were installed correctly, and I also had sound in Google Chrome on youtube

I found the solution to my sound problem on SoundTroubleshootingProcedure.

For me the first tip did the job:

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop  linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop  linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; sudo usermod -aG `cat /etc/group | grep -e '^pulse:' -e '^audio:' -e '^pulse-access:' -e '^pulse-rt:' -e '^video:' | awk -F: '{print $1}' | tr '\n' ',' | sed 's:,$::g'` `whoami`

Cheers

    This solution worked fine until i restarted the laptop (Dell Vostro) for a second time after the installation. Any assistance to sort out this problem once and for all will be greatly appreciated.

    I now have absolutely no sound now. I was able to hear anything except audio for a game before. :/
