According to debug message, it is so, however in config:

>     [Mapping analog-stereo-input]
>     device-strings = hw:%f,1,0
>     paths-input = analog-input-mic analog-input-linein
>     channel-map = left,right
>     direction = input

There is explicit mentioning of required direction.

Sorry, I'm not sure I understand what do you mean by this.
I'm not C/C++ developer at all, can't even find definition of 
snd_mixer_elem_t to find what is that and how to use it (my guess that 
you've being asking about it, right?).

Seems to be the as previous, I really want to help with debugging, but 
you should be more concrete since code is too unfamiliar for me.

I have 24bit explicitly in pulseaudio config currently:

But it still uses 16bit, didn't managed how to force it to use 24bit
