If you look carefully under (Control Panel)->(Sound)[Playback tab]-->Your device/driver[properties button] another window will pop up.
One of the tabs on that window will be "Enhancements" which allows you to do different things to the audio, some offer EQ or bass boost and a bunch of other things, sometimes even things you might never imagine as "Pitch Shift". So as you can see there is some fooling around in the drivers, So between that and possibly a touch of placebo, you never know what'll happen.
I use ASIO4ALL with certain USB devices with my DAW software. I get the best latency and no glitches, which is important with DAW. Well glitches are NFG period.
ASIO = Audio Stream Input Output (recording industry standard)
ASIO outputs a low-latency audio stream from a computer. It bypasses the Windoze KMixer.
