Sound Over-Amplification doesn't work properly after update to 18.04

[prakop]

It's not possible to set the sound level to more than 100% in Settings->Sound menu using the slider. When I switch on the Over-Amplification trigger the Output volume slider remains the same (it used to increas it's max value in 17.10).
BUT it still possible to set volume level to more than 100% in the top bar.

Ubuntu 18.04.1 LTS

Thank you for your bug report. What session are you using? Could you make a screenshot of the sound settings screen you get?

Sorry for late response. Unfortunately I can't make a screenshot for you, because I've moved to 18.10 which doesn't have such problem.
