"Cable goes from USB laptop into USB on cable."
Just to be clear, you have your PC connected to the digital input on your integrated with the Straight Wire usb cable? I'm assuming that you know the H80 actually works because you've used it before with other sources, and you have the input selector set to the proper input.
You don't say what OS you are using, but whatever it is, you probably need to configure it to output digital via usb. Also, depending on your dac, you may need to install a driver.
