Bug#824059: plasma-desktop: When used with pulseaudio, can make people deaf

[Sami Erjomaa <sami.erjomaa@gmail.com>]

I remember having similar problem with kde4 knotify https://bugs.kde.org/show_bug.cgi?id=324975 and https://bugs.kde.org/show_bug.cgi?id=345651. I can still partly reproduce this with KF5 and gstreamer backend by playing notification and adjusting the notification volume to 100%. After this the master volume is raised to 100% but all the other streams are lowered to keep the same voume level.

Since this is probably a very complicated issue that might be caused by pulseaudio,
phonon, vlc as phonon backend or kdelibs, and it will probably take many years to be
fixed, I suggest to ship plasma with a sane default and disable all audio
notifications by default.

The second upstream bug says that gstreamer backend should manage the volumes better. Could you try that?
