You're right, that is the same in my testing. The tuner complains if there aren't any input devices available in Windows.

Specifically, in the Windows sound settings (this is the dialog you get when you press WindowsButton+R and type mmsys.cpl), on the Recording tab, there needs to be one item that is available (both enabled and not disconnected). Stereo mix might be an option if you don't have anything else connected. I'm not sure if this will have an impact on your recording with the USB interface / ASIO drivers?
