IMHO enumeration should not be done just for soundcards, but rather for
"devices" and channels. I was proposing something like that in the scope
of a Resource Manager and Configuration system for ALSA. Unfortunately i
could not go any further beyond some general ideas, because of current
very bad employment conditions :( (no time...).
I posted my thoughts on the ALSA wiki, if someone may be interested:
