I'm using a Lenovo SL500 for several years now and suddenly the Volume keys stopped working. It could be that a kernel updated caused it - I don't know.

However when I go to the keyboard settings -> Shortcuts -> Sound and Media, I can set e.g. Volume Mute with my multimedia key and then it says "AudioMute". But when I later hit the Volume Mute key nothing happens.

Maybe your volume/mute keys got reassigned to some other program? –  Pavel Dec 7 '13 at 10:33
How can I check this? –  tauran Dec 8 '13 at 15:36

I tried a new user account and there everything was ok. So it's definitely a settings problem. However xmodmap -pke gives the same output in both user accounts. –  tauran Dec 11 '13 at 15:36
It's a bug, see here................ bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/… –  user302077 Jul 9 '14 at 23:01

I found a solution: deleting ~/.pulse then logout. Next time it happens I will try the other answer too.

This has fixed my problem, but you must reboot the computer, not just logout, or you may find all the sound controls to be quite broken. I recommending taking a backup of .pulse incase you need to revert. –  Steve May 30 '14 at 8:40
This is the right answer, helped me too. –  Piotr Jurkiewicz Sep 20 '14 at 0:40
Deleted folder and rebooted. This helped in my case as well (Asus N55S). It restored the sound previously gone from the left headphone channel and the volume and mute keys. Thanks! –  Andrea Borga Dec 2 '14 at 22:03

Resetting media key prefrences worked for me

dconf reset -f /org/gnome/settings- daemon/plugins/media-keys/

if it does not work maybe you should try

dconf reset -f /org/gnome/settings- daemon/plugins
