gnome-tweaks is missing the sound panel in my installation of Ubuntu 18.04. (which I need to enable sound over-amplification)
I have gsettings-desktop-schemas version 3.28 installed.
I am using vanilla gnome instead of the default "unitified" gnome of Ubuntu 18.04.
How do I get the sound panel back and is there any other way to use enable sound over-amplification?

  • On my Ubuntu 18.04 the sound panel is located in gnome-control-center, not in gnome-tweaks. Could it be that you're looking in the wrong place? – Frank van Wensveen Aug 23 '18 at 11:04
  • @FrankvanWensveen I think there is supposed to be a sound option in tweak tools. I do have the sound panel in gnome-control-center too but it lacks the option to over amplify the sound. Upon further reading I found out that this option apparently can be turned on from the sound panel within gnome-tweaks (which I lack) – AvZ Aug 23 '18 at 16:11

Having Googled this for you, I find: "There is a toggle switch in GNOME Tweaks but that toggle isn't exposed in Ubuntu because

  1. It duplicates the functionality already in the GNOME Settings app on Ubuntu
  2. The Ubuntu feature still uses a different gsettings key, in part because there are still patches for this feature that GNOME hasn't reviewed yet (for gnome-shell in particular).

So offhand, it doesn't look like you have this opton in Gnome Tweaks on Ubuntu 18.04.

Google also led me here and the suggestion to use 

pactl -- set-sink-volume 0 250%

(for 250% amplification) still works fine on 18.04. See "man pactl" for more info.

  • Yeah I saw the pactl way when I googled this too. I was hoping for a way to get this some way in gnome-control-center. Well anyways, guess I will have to make-do with pactl until Gnome does something. Thanks for the answer. – AvZ Aug 24 '18 at 14:02

In my Ubuntu (18.04) system this command worked:

pactl -- set-sink-volume @DEFAULT_SINK@ 250%
