After returning from the GNOME GUADEC 2017 Developer Conference, Canonical's Didier Roche started a daily blog series, focusing on how the upcoming Ubuntu 17.10 (Artful Aardvark) release will transform from Unity to GNOME Shell . Interestingly, there is a skill hidden in the Ubuntu Unity desktop environment that allows users to exceed the 100% maximum volume limit. If your laptop speakers are not powerful, for example, the volume of the x220 is very low when watching YouTube videos or listening to music with Rhythmbox, then this feature will greatly improve your experience.
Didier Roche said: "If the maximum volume of the device cannot satisfy you, then PulseAudio can help you amplify it some more."
If you are using Ubuntu 17.10 (Artful Aardvark) on your PC, you can first add Canonical's official Ubuntu Desktop Team Transitions PPA to the resource library, and then execute the following command to fully update:
$ sudo add-apt-repository ppa:ubuntu-desktop/transitions、sudo apt update && sudo apt dist-upgrade Sound behavior - ubuntu session
