sk-8115 Knob

I use VoiceMetter to control all of my audio inputs and it uses a virtual interface for it to work. sadly the windows interface wich the dell sk-8115 uses for its knob doesnt control the volume. Is there any way to rewrite the keyboards knob to go to the voicemetter audio? Theres an hotkey app i can use. i have tryed to find the key for the knob for the past weeks and havent been able to get any information.
