I see 2 sliders. No matter which one (or both) I move to say 25%, playing the
next system sound in KDE control panel or e.g. automatically at login time
resets (automatically) both to 66% again. This cannot be intended.

Unfortunately, this has only an effect to a currently playing sound. This was
my first and logical try...

In the evening I will try flat-volumes = no. The the music player cannot set
the master volume any more, but only its own, as far I have red.
