12.04 desktop has no speaker icon

Asked by Darreln

I upgraded from 11.10 to 12.04 last night and while most everything else looks the same I no longer have a speaker Icon in the top panel and thus no quick way to adjust or mute the volume. I have to go to applications/system tools/system settings/sound to adjust the volume. How do I get the speaker icon back on the desktop.

Hi Darreln,

please run this in terminal: unity --reset

That should fix your icon problems. I am sure, that it's here, but unity doesn't show it. When running commmand wait for a while that computer configure unity reset.

If that helps you solve your question, please mark thread as solved.

Regards,
Miha

Hello Miha,

You are on the right track. I ran the unity --reset command in terminal mode and as it was running the Icon came back and the unity panel on the left side of the screen appeared. However the command then locked up and after waiting about 5 or 6 minutes I killed the terminal mode. Maybe the problem is that I am running in Classic mode. I had forgotten about that until the unity panel appeared. I should have included that I am in classic mode in the original question. I have shutdown and rebooted and things are as they were with no speaker icon.

Thanks for your response,
Darrel

Seems you need to install some indicator-*. In Unity it's indicator-sound, in fallback-mode it may be indicator-applet*.

Ok, got it to work. The icon shows up each time I boot.

Used the gnome-session-properties command in terminal mode and added the gnome-sound-applet to the Startup Applications. This fixed the problem. I could not use the alt-f2 for the Run Application mode because alt-f2 does nothing on my system. I suspect because I am running in Classic mode.

Thanks to all,
Darreln

Darreln, actually alt-f2 is typical for Gnome environment.
Verify keyboard -> shortcuts -> system in system-settings aka gnome-control-center.
Other options:
gconf-editor
/apps/metacity/global_keybindings: panel_run_dialog <Alt>F2
or
ccsm (compizconfig-settings-manager)
gnome-compatibility: run-dialog <Alt>F2
