It's true, the USB drivers have always been finnicky, but I've always managed to get them working without too much bother. I think I've hit the end of the road this time, though.

Luckily, another user in another thread gave me the good idea of getting a USB > optical converter instead, which should help me get around the issue.

I use a Resonessence Concero as DDC between PC and NFB11.32 for everything barring DSD playback and S/PDIF definitely sounds best to my ears.

Be advised that I only use the Audio-gd as a pure DAC with output fixed to the amp of my choice.
It is a far better DAC than amp IMHO.
