I really dont want to buy foobar.I feel i have spent enough already:(
Foobar2000 is free, the WASIPI plugin is also free. Google "Foobar WASAPI setup guide" if you need help setting it up, there is a lot of excellent setup tips out there, you are not the first person to run into trouble.
In all likelihood you will get better sound using Foobar with the plugin because it bypasses Windows native drivers.
Use WASAPI with Vista, only XP uses ASIO.
