Why is Asio4all isn't working in Fruity Loops when trying to record? By the way, I'm using Windows 8 on a Satellite Pro laptop.
The problem with Asio4all is that it does not have full Windows 8 support. On the CHANGELOG page at the official website, Windows 8 is not mentioned as a supported OS. This could either mean you'll have some issues, or it might not work at all.
