After I installed and uninstalled lxde with Ubuntu 16.04, I cannot hear any sound in Ubuntu after logging in with my user (at the login screen, it works).

It started with (from history | grep apt):

 149 sudo apt-get install lubuntu-desktop 
 166 sudo apt install --reinstall ubuntu-desktop
 167 sudo apt install --reinstall ubuntu-desktop && sudo apt install unity
 168 sudo apt lightdm restart
 170 sudo apt autoremove 
 172 sudo apt install --reinstall ubuntu-desktop && sudo apt install unity
 176 sudo apt remove lxde-core 
 177 sudo apt remove lxde-common 
 178 sudo apt autoremove 

And afterwards, the sound was not there anymore (maybe even earlier and I did not recognize).

After some tries (with reboots in between) the sound did not work either:

 194 sudo apt remove alsa-base 
 195 sudo apt autoremove 
 198 sudo apt-get autoremove pulseaudio
 199 sudo apt autoremove 
 202 sudo apt install pulseaudio
 206 sudo apt-get remove alsa
 207 sudo apt autoremove 
 210 sudo apt-get remove alsa-base alsa-utils
 212 sudo apt install indicator-sound
 213 sudo apt-get remove --purge alsa-base
 215 sudo apt-get remove --purge alsa-base
 216 sudo apt-get remove --purge pulseaudio
 217 sudo apt update && sudo apt upgrade
 219 sudo apt-get install alsa-base
 220 sudo apt-get install pulseaudio
 224 sudo apt install indicator-sound

But when I created a new user and logged in as that one, it worked. I've read this article, Sound not working in Ubuntu 14.04 and No sound-indicator after login but did not find any solution for the problem that the sound is only unavailable for one user. It seems like it is a configuration issue of this user. In the home folder, the following configuration files are present:

Deleting .config, .gnome2, .gnome2_private and .local and then logging out and back in did not change anything. Has anyone an idea where the wrong configuration may be?

I had the same problem yesterday.
I installed Jack and after a reboot I encountered this.

After a little searching I came out with this solution.

1. Uninstall JACK




2. Go to directory ~/.config/pulse/




3. Remove all the files located there.

Suddenly, I found my output devices started to show in sound settings.

Hope this helps.

I was in the same situation when a new user had sound but I had not after probably screwing something up with apt.

In alsamixer my sound card was displayed, but in settings -> sounds not.

It was solved when I copied (as new user):

/home/newuser/.config/pulse/*

to (as new user; also don't forget to mkdir this):

/home/newuser/pulsecopy/

because the user can't access the other users .config and then to (as original user)

/home/originaluser/.config/pulse/

Could this copying be done from a LiveUSB session and not have the "new user" work?

Quoting for reference:

try this command
"pulseaudio -D"
