I think Leif was asking how to write drivers for the sound hardware 
device to alsa-lib interface(i.e. What alsa-driver/alsa-kernel does) and 
not the application to alsa-lib interface.
Maybe I will write some documentation when i attempt to write a new 
hardware driver myself. I am thinking of writing one for the dxr3 mpeg2 
decoder board, which has a simple audio out jack on it, which currently 
only have oss support.

Cheers
