My sound has been working fine until recently.I lost sound and the sound control on the menu bar.When I reboot all I get is a clicking sound. When I managed to get back the sound control, it had an x against it. When I clicked on it the sound was muted and I could not unmute it.

Also my sound card was not there any more, where it had been before. My sound returns by clicking on the Ambient Noise icon. I've looked around the internet for answers and tried a few things without success. Does the following mean anything to anyone?

sudo apt-get install indicator-sound

I'm a fairly new user, so as indicated above, do I need to delete some unwanted files to bring back the sound control?

Install the indicator-sound package which provides the normal ubuntu volumecontrol via the command

sudo apt-get install indicator-sound

and to make the change take effect do

killall unity-panel-service

if this didn't work than run following command in terminal

gsettings set com.canonical.indicator.sound visible true

and you will be good to go

  • Can you make it a bit clearer please.

  • when I enter killall unity-panel-service, nothing happens. Do I need to add something?

  • My sound indicator randomly vanished. The gsettings worked for me, thanks Nitesh, but why did the sound indicator vanish in the first place I wonder.
