People were worried about the maintainability of this (proposed as shipped 
/usr/share/cards/<card>.state files) but I feel this shouldn't be too bad 
indeed. I'd suggest "alsactl defaults" to just load those "unmuted card 
defaults" and leave looking for previously saved settings to an init script 
same as now. Distributions then have full freedom.

Is the "id" parameter to modules (and multiple cards with the later ones 
having an id postfix) a problem for finding the right state file to load? 
That is, is it a problem for the current <card>.conf files in there? Not 
sure how that works...
