Bug#735842: meta-kde: KDE notification service sets Amarok volume to 100%

Hi,

I have the same problem and can repeat it by generating notifications for example with Shift+Del on file and found a way how to change the max volume.

in System Settings > Application and System Notifications > Player Settings (tab) "Use the KDE sound system"-volume.

It seems that if the current volume is less than the volume set in there the volume will be raised to that volume but not lowered.

Hopefully this helps debugging this problem.

Just as additional input: I've seen this behavior with other sources than this
virtual terminal notification thing.
Hasn't happened in a while so I can't remember what triggered it last time. I
think it was a _javascript_ popup in Konqueror.

In my case the master volume got set to 100%.
