Sometimes after installing XFCE/Xubuntu along side Ubuntu LightDM the configuration for your present and active sound devices will get overwritten or removed. The first thing you should do is go to “Application Menu -> Multimedia -> Pulse Volume Control” Click the “Configuration” tab and check what audio devices it is listing. If it doesn’t display any skip to the section titled “Update”.
Check:
If it shows your sound devices click the “Output Devices” tab and make sure the sound device which should be outputting sound is not muted and that it has “Speakers” or “Headphones” in the “port” dropdown box which ever the case may be. Your sound should be functional now
Update:
If the “Configuration” tab doesn’t show any of your audio devices run the following commands from a terminal window.
killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse* If it says it couldn't remove the files in question it means pulse never created them when it was loaded.
Now run the following commands from terminal, once they have completed reboot your computer, once you are back in XFCE open “Pulse Volume Control” and follow the directions from the section titled Check.
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`
