forward sound from source to V2100

Hey,

I just got my new V2100. Before I have been using Logitechs G35, and for easy sound management I had set a virtual audio cable, that I would forward to the G35 via the windows options. While this has been working really well, I can't seem to accomplish that with the V2100. I went to recording devices, selected the virtual audio cable and set it to forward to the V2100, but it doesn't show up in the mixer. As I can't seem to find any mistake on my side, is that just another downside on the drivers?

Any help is appreciated.
