One thing that may help, is if someone could provide a mapping of the wolfson registers as 
documented in the WM8753L pdf to the alsa controls. Someone had to have written the code that 
twiddles the registers in that chip, and would know which also control matches which register.

I looked at the obvious choice which would be a 1:1 mapping of also control number to register 
number, but that doesn't match even closely.
