Public bug reported:

after switch to pulse 6 pavucontrol/kmix behavior changed in a bad way
and sometimes jumps to 100%

some applications (i made some howto) just let them jump to 100% wich is
bad, because when you play a loud song this can cause ear damage and
hardware damage.


(how to recreate)
be in KDE Plasma, go to dolphin and to your settings. now loog at the trashcan 
menu whats the maximum size. close and create a file  bigger as the maximum. 
trs to move that file to the trash. a notification will show you that you cant 
move it to the trash can AND pulseaudio will jump to 100% for your master 
channel
