Cannot Get 5.1 Recognised

I'm using parallels Mac with windows virtual and cannot get 5.1 sound working. Parallels recognises my X4 sound card and is selected, but windows sound settings just sees the default speaker setup. ive tried installing the X4 driver into windows, which did nothing and ive tried giving windows access to the X4 over the Mac, but then it stops playing any sound.

I've followed the steps in the guideline below, up to the guest os part:
