I agree that initialization should be implemented in alsactl, too. I think 
that only necessary values (Master, PCM, Front, Wave, enable recording 
from Mic) should be kept in database and all other "advanced" controls 
should be untouched. Initial values should be hearable minimum.

I'll try to propose and implement an interface.
