All we know that the version Ubuntu 17.10 is months away and Ubuntu development team is working for us to enhance our Ubuntu experience by adding new features and fixing the bugs. We got an new update that the upcoming Ubuntu 17.10 will include the feature that can automatically mute the music while you are taking call. Its Pretty awesome isn’t it.
This feature is provided by an PulseAudio Plugin called “Cork”. Cork was disabled due to some QT based Skype client issue. As the QT based Skype client is no longer available. The Pulse Audio team have decided to enable the Cork Plugin.
