Russell Treleaven helped me on Alsa bugtracker :
https://gitlab.freedesktop.org/pulseaudio/pulseaudio/issues/617
He found that when Pulseaudio Capture level is more than 21%, Line boost, Mic
Boost and Internal Mic Boost are always at Max in Alsamixer and then, nothing
is recorded.
With Alsamixer or Pavucontrol, it's possible to set correctly all levels and to
activate Capture 0 and Capture 1.
But each time I'm using again Linux Mint MATE or Ubuntu sound control
panel, if I put Pulseaudio Capture level at more than 21%, capture
doesn't work anymore again !

Title:
Internal microphone doesn't work with Realtek ALC268 chipset
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
I have this problem with Ubuntu 18.04, 18.10 and Linux Mint 19, on my HP
Pavilion dv6700, with a Realtek ALC268 chipset.
Audio is working but not internal and external microphones.
As explained in https://elubuntero.wordpress.com/tag/realtek-alc268/ ,
I tried to add linux-backports-modules-*** but this package isn't
anymore in Ubuntu and Mint repositories.
I tried all options as explained in https://doc.ubuntu-
fr.org/audio_intel_hda, without result.
