I've a small problem with my sound control under Linux Mint Daryna.
If I try to control the system sound with the function keys and [LEFT] [RIGHT], an image apprears which display the changings of my commands. (louder, quieter, ...). But these control does not control the system sound. That does not take any changes on the volume of for example amaroK.
That worked, but now it does not work anymore
What can be the problem?
(I hope you understand what I want to say
