I'm running Kubuntu 18.04. In Xenia 20.04, it seems that you need the modules indicator-sound and indicator-sound-gtk2 to get the volume control on the taskbar. But that doesn't work in 18.04. So what do I need?

I think the problem lies in some configuration file, since when I created new user, that user did have the sound indicator.

You can try this:

sudo apt-get install indicator-sound
killall unity-panel-service
killall gnome-panel

or

sudo apt-get install indicator-sound
sudo apt-get install indicator-messages
sudo apt-get install evolution-indicator

Hope this helps.

  • Unfortunately that didn't help. Those programs were already there. I tried reinstalling them anyway -- no difference. I suspect the problem lies in some configuration flle. – Paul A. Sep 07 '20 at 15:24

You can even try this, it worked for me.*

sudo apt-get purge pulseaudio
sudo apt-get clean && sudo apt-get autoremove

Reboot. Open a terminal again and type (ignore any errors with the rm command):

rm -r ~/.pulse ~/.asound* ~/.pulse-cookie ~/.config/pulse
sudo apt-get install pulseaudio

Note: if you get E: Unable to correct problems, you have held broken packages. error, then you can try: sudo aptitude install pulseaudio
(if you don't have aptitude on your machine: sudo apt-get install aptitude)

sudo alsa force-reload
pavucontrol

The last command should restart the PulseAudio server and launch a desktop application for its settings.

*Note: Using apt instead of apt-get may work as well.

  • Unfortunately that didn't work either. I do have sound, but not a global volume control (the loudspeaker icon). – Paul A. Sep 09 '20 at 21:28

Hooray -- I got my loudspeaker icon back. The trick was installing kubuntu-desktop. Seeing that work explained why none of the other suggested solutions worked. I had been climbing the wrong mountain.
