Hmm...Sorry for asking a stupid question that how to test bypass path with WM8962? I've tried some amixer commands to enable the bypass-path switches. But we still need to power the Codec up like using arecord or aplay to call wm8962_resume() and DAPM-related, right?
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.
