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`

Install ATI official drivers in Ubuntu

I find myself pretty often installing or re-installing my official ATI drivers for my video card. So here is a safe guide which will guide you through all the steps.

For a 64 bit system, install this first:

sudo apt-get install ia32-libs

Run each of these, one at the time, if getting any faults ignore it.

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

Remove your xorg.conf file

sudo rm /etc/X11/xorg.conf

Re-install xorg

sudo apt-get install --reinstall libgl1-mesa-glx:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:i386 libgl1-mesa-dri:amd64 xserver-xorg-core

Configure xorg

sudo dpkg-reconfigure xserver-xorg

Reboot:

sudo reboot

After the reboot all the fglrx packages will be gone, you will be using default ones.

Download the newest ATI driver (current version is 12.1)

wget http://www2.ati.com/drivers/linux/amd-driver-installer-12-1-x86.x86_64.run

Once downloaded go to the file location and set it to run as executable

cd /path_of_the_file
chmod 755 amd-driver-installer-12-1-x86.x86_64.run

Use these steps to install

sh ./amd-driver-installer-12-1-x86.x86_64.run --buildpkg Ubuntu/oneiric
sudo dpkg -i fglrx*.deb

Once the driver is installed you need to start up a new xorg.conf file with this command

sudo aticonfig --initial -f

Reboot

sudo reboot
