The over-amplification setting is an Ubuntu-specific patch. Although collaborated on with GNOME Design, it doesn't look like GNOME is interested in it at this time.
In order to try to keep the vanilla GNOME session close to upstream, Ubuntu's patch only affects the Ubuntu session. (The slider does go past 100% in the Ubuntu session.) The upstream tracker bug for this new feature contributed by Ubuntu to GNOME 3.28 (but not gnome-control-center in particular yet) is https://bugzilla.gnome.org/show_bug.cgi?id=790988 ** Bug watch added: GNOME Bug Tracker #790988 https://bugzilla.gnome.org/show_bug.cgi?id=790988 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1755982 Title: Cannot go beyond 100% sound level anymore in GNOME session Status in gnome-control-center package in Ubuntu: New Bug description: Since very recently, overamplification (going beyond 100%) is missing in sound settings, when running in GNOME session. In Ubuntu session, there is a switch to enable overamplification, but I don't know if it does anything. The UI with a slider that went beyond 100% certainly worked better, and was available in gnome session too.
