General :: Can't Map XF86AudioRaiseVolume Key In QJoyPad

I wanted to map my PSone gamepad to do some basic KDE/keyboard/mouse functions and everything works well except one thing. I use logitech ultra-x keyboard which has a few multimedia buttons (play, home, volumeup, volumedown..) and I wanted to map volumeup and volumedown keys to my pad with everything else.

volumedown works well, but volumeup makes some trouble. after I start qjoypad and map it - it does work but after mapping it I still see the "[NO KEY]" (while it is doing its job - volumeup; that's strange).. after I turn qjoypad off and on I get this error: "Error reading button 6" and after that "Error reading definition for joystick 0"

this is my layout:

QJoyPad 4.1 Layout File
Joystick 1 {
Axis 4: gradient, dZone 6505, maxSpeed 11, tCurve 2, sens 2, mouse+h
Axis 5: gradient, dZone 6264, maxSpeed 11, tCurve 2, mouse+v
