Logitech Wave Multimedia Keys Not Responding

I am using Logitech Wave wireless mouse and keyboard set. On Linux Mint KDE there is no problem. Buttons work well. But on Netrunner Linux, when I push multimedia buttons (e.g. Volume up, volume down, mute…) nothing happens. How can I fix this problem?
Thank you for help and sorry for my bad English.

Have you tried setting up the buttons in the sound settings.
Right click on speaker icon in panel.
Click on Veromix setttings.
Set up buttons in the Volume keyboard shortcuts

Worked for me. :cool:

Hey, thanks, Stennie, worked like a charm for me. Was missing my keyboard volume control.

Thank you @stennie. It worked.
