Ubuntu – Sound settings are missing

alsagnomepulseaudiosound

I know there are tons of topics with that name, but I just can't make it work.
I had alsamixer from start and it didn't show me sound settings except for mixer itself.

I tried to install gnome control panel, and now when I right click on volume and choose "Volume control" settings, I don't get even alsamixer to appear. Instead I see 1 extra sound icon of gnome control panel, which when I right click on it shows me button "Sound preferences" while it opens just control panel without settings in it… What should I do?

This is what I have in control panel

Also… I have noise in my earplugs when I don't play music, I can't fix it either even though Power saving is false.

Install gnome control center and pulseaudio again to fix this issue:

sudo apt-get install gnome-control-center

If still doesn't fix your problem:

sudo apt-get install ubuntu-desktop

If after installing gnome-control-center you still have noise problem try to install pulseaudio:

sudo apt-get install pulseaudio
