You mean AOA?
ASoC doesn't do any dynamic module handling by itself, AFAIK.

Well, originally there shouldn't have been so many codec variants.
The current situation came up due to a couple of obvious reasons...

Ayway, the current plan is to develop an improved generic parser and
add the capability to extra setup for each hardware, either
dynamically or statically.  In that way, the whole static function
callbacks and mixer arrays can be removed or replaced with smaller
hints.

The codec reconfigure patches are already in my tree in
topic/hda-reconfig branch, and the improvement of generic parser is
under development.
