sound/pcm contains generic code.
sound/pci is most probably the part you want to understand most. It
contains the hardware specific parts. Not all drivers there are on the
same quality/maturity level. No idea which is the best one to look at.

Maybe the following link helps a little bit with understanding more
easy what is used where (automatically generated out of the FreeBSD
