Yes I have it running through my usb port and I do have foobar with the WASAPI plug in installed. It's just not an option under preferences > playback > devices. My directx is up to date for win 7. I did remove my on board sound drivers and disabled it in BIOS when I installed the asus essence stx sound card. I don't think there's anywhere in windows where I could have uninstalled it by mistake either. Should it be shown in device manager (in control panel)?
