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?

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.

In my Ubuntu (18.04) system this command worked:

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