PulseAudio, by itself, auto-adjusts microphone input only if 
module-echo-cancel is loaded. However, it is not the loaded by default, 
so it's more likely that some application (Skype or Chromium, most 
probably) adjusts the gain for you.

For further troubleshooting, please provide the output of these two 
commands (run them as your user, not as root) when you find that the 
microphone gain has been adjusted against your will:

LC_ALL=C pactl list sources
LC_ALL=C pactl list source-outputs
