Microphone volume very low when routed through Pulseaudio

I wasn’t referring to the ALSA mixer, just where it sits with respect to PA. I tend to install pavucontrol as a matter of course since it provides an easy way to configure sources, sinks and respective levels.

With so much time having gone by, another look at the output of the alsa-info.sh script might be useful to see if it yields any hints.

Else this could be bug reporting territory.
