Looking to learn linux. Audio not working. Windows says realtek hd audio

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa; sudo apt-get update;sudo apt-get dist-upgrade; sudo apt-get install pavucontrol linux-sound-base alsa-base alsa-utils lightdm ubuntu-desktop linux-image-`uname -r` libasound2; sudo apt-get -y --reinstall install linux-sound-base alsa-base alsa-utils lightdm ubuntu-desktop linux-image-`uname -r` libasound2; killall pulseaudio; rm -r ~/.pulse*; ubuntu-support-status; 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`

Run that as one big command and reboot to test

Hi, thanks for your help! The commands and downloads were successful, but unfortunately after the reboot there was still no sound. I noticed while ubuntu is booting I see some errors on the screen. I'll try to save those but they flash quickly on the screen and they're gone. I was already burned out when I posted the question so I'll check it out more and be fresh tomorrow. Thanks again.

Wanted to add to this... If you check the device id I posted above, it has 10ec for the vendor id which I believe is Realtek. When I run:

cat /proc/asound/card0/codec* | grep Codec

It comes up with:

Intel Haswell Hdmi. Hope that helps some. Thanks again.

More info....

If you run:

alsamixer

Are all levels maxed and unmuted? Use cursor keys to edit, M to un/mute and ESC to exit. Also use F6 in alsamixer to make sure you are selecting the right device for output.

Then run the 'sound' application in Dash and repeat, be sure to try all sound devices for output.

Also try some headphones in the system, see if they work.

Ubuntu does indeed see the Realtek codec used for analog output:
Codec: Realtek ID 233

I'm seeing all kinds of audio issue reports with the 3.8.0-34 kernel, so you may have picked a bad time to upgrade. If you haev another kernel to try, it may work.

Thanks for your answers. I tried checking everything is alsa mixer and tried 3.5 kernel. I'm too new to this to figure it out. I installed 12.04 on my desktop to mess with and everything is working out of the box. :)
