I had a "dummy output" problem and started messing with the terminal. After trying multiple users' solutions I decided to uninstall pulseaudio and use alsamixer instead. That didn't fix my issue, rather it just got rid of the volume system tray that I would like to get back.

I used sudo apt-get autoremove pulseaudio to uninstall then sudo apt-get install pulseaudio to re-install but all of my issues are still the same, and the system tray volume icon isn't back after re-booting either.

How do I get my sound devices to output properly and the volume tray back?
Also, the hdmi output disappeared from PulseAudio Volume Control.

  • Also, when you have a dummy output problem, see my answer here: askubuntu.com/questions/491346/how-do-i-get-my-sound-working – mchid Jul 18 '16 at 22:56
  • I can't get past the first command as the terminal throws back Failed to stop pulseaudio.service: Unit pulseaudio.service not loaded. (first command being sudo service pulseaudio stop) – HelpMeee Jul 18 '16 at 22:58

    Then keep going. It can't restart if it's not started. – mchid Jul 18 '16 at 23:00

    Just ignore the service commands as the newer versions of ubuntu don't seem to run that as a service anymore. – mchid Jul 18 '16 at 23:03

Okay, a simple run of the following command:

apt-cache search pulse | egrep 'tray|indicator'

returns the following:

indicator-sound - System sound indicator.
indicator-sound-gtk2 - System sound indicator.
pasystray - PulseAudio controller for the system tray
pnmixer - Simple mixer application for system tray
volti - control audio volume from system tray/notification area

Although, I think what you are looking for is indicator-sound as the tray icons are called indicators for unity. In any case, run the following command to hopefully install the system tray icon you are looking for:

sudo apt-get install pasystray pnmixer volti indicator-sound

reboot.

If you are using unity, you might be able to skip a reboot by running the following command:

indicator-sound &

For Kubuntu:

Run the following command to install the systray icon:

sudo apt-get install kmix

Start it up using the following command:

kmix &

  • I get almost the same output (only volti is in a different line) indicator-sound - System sound indicator. volti - control audio volume from system tray/notification area indicator-sound-gtk2 - System sound indicator. pasystray - PulseAudio controller for the system tray pnmixer - Simple mixer application for system tray after inputting the second code in the terminal and rebooting, the volume is not back on the system tray – HelpMeee Jul 18 '16 at 22:56
  • @HelpMeee What does it return when you run indicator-sound & on a unity desktop. – mchid Jul 18 '16 at 22:58

    @HelpMeee I see, I have changed the commands to use kmix instead. – mchid Jul 18 '16 at 23:19

    @HelpMeee To get rid of the second tray icon, you can uninstall kmix. – mchid Jul 18 '16 at 23:24

    Thank you for letting me know. Posted separate question here: askubuntu.com/questions/800262/persistent-dummy-output – HelpMeee Jul 18 '16 at 23:37
