My sound chip doesn't support ASIO natively, so the onyl way form e to do asio was using asio4all, which isn't really a realistic way to write the ASIO code. I stopped coding it when the DSound module was good enough, mostly because I didn't feel I needed it anymore.
i'm not an audiophile and I don't really have much money to spare atm (/me hints at the donation button in his googlepages site).
