Most likely, your Vista 64-bit machine has a generic Vista 64-bit (High Definition) audio driver, instead of a specific audio driver for your machine's sound card. It seems PortAudio does not like the generic audio driver from Microsoft, even though you can play audio/video fine with Windows media player or Real Player. This is from my experience. I installed Windows 7 on my old PC. At first, PortAudio failed to pick up sound device before I installed proper audio driver. When I finally installed proper audio driver, PortAudio works perfectly. Good luck to find a proper audio driver to your OS!
