Dude, I wrote that wiki page for a reason: so that people read it. So read it again: http://pulseaudio.org/wiki/BadDecibel File a bug against the driver/kernel in your distro bug tracker. And explain that the dB data for your volume step 0 is invalid and that it needs to be fixed to be more like -inf dB. I am pretty sure your distro folks will then help you to make sure this gets fixed in the kernel. Include the output of alsa-info.sh --no-upload there.
