Hehe, I'm just a 'translator' here. But going by you answer I'm taking
it there isn't in fact a rate-limit to adjustments. Which, even if you
were not opposed to that direction, makes it an unfeasible proposition.

Also, I'm not thinking its too mythical, sound/soc/intel/ is full of
audio DSP stuff, I think a newer version will just gain ART support.
