Your output did not include source usb audio input
Do you mean your usb audio are not default source ?
What is the default source ? alc892 analong input, alc892 output monitor,
usb output monitor or usb analog input

What do you mean "not working properly" ?
Are you complie and run from git ?

wrong, but I have no idea what.
when pulseaudio did not find dB scale or user specify ignore dB scale ,
pulseaudio just set volume to maximum and use software volume
It use snd_mixer_elem_set_capture_volume instead of snd_mixer_elem_s
