  Microphone not working in Ubuntu 18.04.3 LTS on new hp-
  spectre-x360-convertible-15 laptop

Status in alsa-driver package in Ubuntu:

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).
