That warning is about using the internal audio in laptops. Assuming the usual mobo sound chip, you'll find the Tool of Satan if you go Control Panel > Sound, double-click on the default audio, and click the Advanced tab. The checkbox for "Enable Audio Enhancements" should be labelled "Destroy any Semblance of Audio Reality." Or more simply, "Enable Tool of Satan."
Thanks for posting, Noel! I had so many people come up to me and ask for me to do this presentation online somewhere and archive it...guess I need to do it in my spare time LOL.
