I haven't got a lot of help for you as I'm not knowledgeable about this 
but I can give you
some suggestions.

You could ask you question on alsa-devel mailing list as they know the 
internals and might be able to answer your question directly.

You could look at the alsa driver code.  Go to 
ftp://ftp.alsa-project.org/pub/driver/ and download 
File:alsa-driver-1.0.16.tar.bz2. 
<ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.16.tar.bz2>
This is the latest official alsa version.  Unpack it and then look in 
"top level"/alsa-kernel/pci/emu10k1.  That has the C source.
