For this sort of question you should follow the DAPM graph... the headphone and speaker mixers have IN4 and MIXIN as inputs for analogue bypass and the STL and STR paths provide digital sidetones through the ADC and DAC.
So I could test it merely by using 'amixer cset' to enable those switches without doing anything to power WM8962 up as long as my operation follows the DAPM graph so that the DPAM would automatically turn on the regulator for me?
Yes, as soon as you have a complete path from an active input to an active output the path should get powered up.
I'll try again tomorrow. Thank you sir.
