I've recently switched platforms and my new motherboard no longer has a PCI slot so I had to ditch the Xonar ST. :( I've been looking into a couple of USB DACs in the meantime and I've settled with this one, the Audio-GD NFB 15.32 with the TXCO upgrade, I've read good things about it, it seems a nice deal for $250 and everybody seems to like it. I have a rather simple question for those who have the DAC: Can I get sound through USB to the DAC no matter if I'm gaming or listening to music with foobar? I know I could manually switch between listening to music on USB vs. having data sent through SPDIF with my motherboard's output but it would be kind of nice to have only one cable running from my PC to my DAC, preferably USB. Is this possible? I'm running Windows 7 Ultimate x64, by the way. :) Thanks in advance.
