Public bug reported:
This is intentionally a duplicate of bug #1817485 to collect info on a
fresh vanilla install of 18.04.2 after updating to prove that Ubuntu's
default session is also effected. I just wanted to collect all pertinent
logs to prove that this was in fact an unmolested install.
As in the previously filed bug report once over-amplification is
switched on only the volume slider in the top panel actually increases
the sound above 100%. Neither the slider in the sound settings UI or the
keyboard volume hot keys will increase the sound above 100%.
So, in use as an HTPC, if you're streaming content in full screen and
have the sound set above 100%, when a blaring loud commercial comes on
and you turn the volume down with the keyboard hot keys you can't use
the keyboard hot-keys to return to that over-amplified state.
I'm attaching a screenshot and I'll also update this with a full step by
step process to reproduce the bug. Either a reboot or logout is required
for the changes to take effect after switching over-amplification on (or
maybe off too). I just need to rinse-n-repeat a few times to be sure so
you won't have to waste time trying to reproduce.
