With the latest stable versions of the audio stack on openSUSE Tumbleweed I
have also observed mismatches between PA and ALSA with my Thinkpad T530. In the
case of my internal integrated mic Capture level, 100% in `alsamixer`
corresponds to only ~33% in the `pavucontrol` Input Devices tab. Anything
beyond ~33% in `pavucontrol` starts enabling mic overboost in `alsamixer`,
which causes distortion.
