At a guess & I ain't an expert, I would have thought that a look at the source 
code for alsaconf, kudzu &/ discover or even soundconfig or whatever would be 
enlightening here. Or even just the man pages:
Kudzu detects the current hardware, and checks it against
       a  database  stored  in  /etc/sysconfig/hwconf.
discover provides an extensible hardware detection and reporting inter-
       face.  Hardware  information is stored in an XML data format and can be
       retrieved across the network. Try /usr/share/list.xml.
If you can come up with something that works better than alsaconf on Debian 
(i.e. works ;-) I for one will be interested in your results.
Not quite in the same league, but also very useful is 
http://alsa.opensrc.org/?aadebug for simple alsa diagnostics.
