Ubuntu – How to disable the popping sound when changing the volume in KDE/Kubuntu


I've just upgraded Kubuntu from 12.04 to 14.04, and (as expected) there are several annoyances. The first one I've tried and failed to solve is the "popping" sound that is played whenever I change the volume, with the mixer or with the volume keys. I have enough with the OSD, I don't want any sound.

I have "no audio" selected in the notifications setting, but that doesn't help.

Something else I've noticed, and don't remember it was like this before: when a system tray menu is displaying, the volume keys do not work…

And look in notification area there should be broadcasting speaker; click on it.You get dialog box with few buttons Select the button with Spanner on it. A window will open named "Configure KMix". In that window on left hand there will be General option. In General option you will uncheck the "Volume Feedback". close window. Right click on speaker in notification area select Quit.
