Keyboard Volume Button Not Working

Hi, I installed 13.06, but could not get Netflix to run in it. So. I’m back on 12.12.1 and have already had a few issues with this version as well. My exact keyboard I used on the 12.12.1 OS originally, the volume button worked fine. Now it’s not.
How can I get it working?


Please try to go into systemsettings -> Schrotcuts and Gestures -> Global Keyboardshortcuts . Choose there Kmix from the dropdown and try to set the actions for decreasing and increasing volume.
