That was going to be my approach too. In this case, which virtual driver sample would you start out with? It's important that audio from player through virtual driver to application will be bit correct, and that the application (which knows the hardware) controls the timing during playback. > But, in that case, what's the point? Well, the application may already have a way to access the hardware outside of established audio infrastructure. This is the case with the Audio Widget ASIO driver where the library uses libusbK.
