I just upgraded to 12.04 I have sound. Using headphones also mutes the speaks. So far so good.

I can't use my shortcuts to control volume anymore. It's usually Fn + Left Arrow and Fn + Right Arrow.

In top right corner, the volume bar looks like the volume is all down. Clicking on it, I can go to Sound Settings... and it seems I can't use that application. It opens, but I can't click on anything and basically there is nothing to click on. It's greyed out with no information.

What do I do? I can control volume through Gnome Alsamixer... or whatever player I play music from (so it seems. I tried Rythmbox... and youtube). But it still seems the sound application doesn't work.

I've got a lenovo U350.

Try killing and restarting pulseaudio, do some /tmp cleaning too. Open terminal and type switch to root using "sudo su" and then do the following:

killall pulseaudio -KILL

rm -rf /tmp/pulse-*

Exit root by pressing CTRL+D and restart pulseaudio by typing: pulseaudio -D
