That is because the ucm is not loaded successfully.

please change cset "name='Headset Mic Boost Volume' 1" to cset "name='Mic Boost Volume' 2" in the all LENOVO_*/LENOVO_*.conf; then reboot.

If it doesn't work, please upload log of "pactl list cards", maybe your machine has a specific dmi string that those 4 folders doesn't match the cardlongname of your machine.
