By cleaning-up/rewriting my code, I get the bypass working.
Now I will try to put a mixer widget referenced "Mixer, Adder, Balance" 
in "Audio Ouput Section Diagram" of User's guide to be able to select 
which analog audio stream will be fed into selector then I will add 
control to be able to select needed SOC_DAPM_OUTPUT.

Is there a way to defined state of a SND_SOC_DAPM_SWITCH to 1 or 0 by 
default ?
