I am on the HP 830 G6 and with 'options snd-hda-intel index=0 model
=laptop-dmic' I finally see the microphone appearing in pavucontrol.
However, I cannot get the microphone/input working.
Currently, I have the following lines added to make at least output
sound working and *see* the microphone in pavucontrol:
options snd-hda-intel dmic_detect=0
options snd-hda-intel index=0 model=laptop-dmic
My system is as follow:
$ lsb_release -a

Title:
Microphone not working in Ubuntu 18.04.3 LTS on new hp-
spectre-x360-convertible-15 laptop
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
Internal Microphone does not work in Ubuntu 18.04.3 LTS in a new hp-
spectre-x360-convertible-15 laptop. The microphone works perfectly on
Windows 10 (present in Dual boot mode).
Initially, Internal Microphone was not even detected but installing
alsa-tools-gui and overriding pin 0x12 to the Internal Microphone
fixed that issue. [Pin 0x13 does not work and causes static in a
headphone if it is plugged in.]
Microphone is not able to pick up any sound. I changed levels/settings in
alsamixer, pavucontrol without any success:
In alsamixer: Experimented with levels ranging from very low to very high for
Internal Mic, Capture, etc.
In pavucontrol: Set the Internal Mic as a fallback device, unlocked the
channels for the mic, experimented with reducing the level for one of the
channels (reduced right mic level to Silence while keeping the left mic level
normal/high and vice versa).
