In addition to the accepted answer, you can check out the following post: Disable PulseAudio Auto Volume.

This post indicates that you can edit the following files as root:

sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-dock-mic.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-front-mic.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-headphone-mic.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-headset-mic.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic-always.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-mic.conf
sudo emacs -nw /usr/share/pulseaudio/alsa-mixer/paths/analog-input-rear-mic.conf

And update the following fields wherever you see them in these files. You don’t need to update volume if it’s set to off. Only devices that are awake need to be adjusted.

Restart the computer for the changes to take effect.
