[Touch-packages] [Bug 1840725] Re: Microphone not working in Ubuntu 18.04.3 LTS on new hp-spectre-x360-convertible-15 laptop

2020-04-08 Thread Louie McCrady
I tried using the:

options snd-hda-intel dmic_detect=0
options snd-hda-intel index=0 model=laptop-dmic

in /etc/modprobe/alsa-base.conf

All it did for me was add a new microphone to the selection list in the
settings.  Neither build-in selections work.

Spent a little time looking through some files, but didn't find anything
that stands out.  It will take some time looking through files, and
scouring websites.  I might spend some more time looking into it again,
because I find myself needing a microphone lately.  and, I have a little
time on my hands lately.

  Microphone not working in Ubuntu 18.04.3 LTS on new hp-

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).

2020-04-08 Thread Louie McCrady
I've had an HP Spectre 360 with HP dock for 5-6 years, and this has
always been a problem, and it still is.  I traced it down one time to
the script that detects the available audio input devices, and sets the
default.  The script is poorly written and is hard to follow.  It
detects that there are two microphones.  Then correctly sets the default
microphone to what the user specified, but then it sets it again, to the
last microphone detected.  In my case, it was the non-existant
microphone on the HP dock.  This script got written over by some update,
and I haven't had the time to track it down again.

I'm still seeing this in 20.04 beta, the difference is now it no longer
remembers my selections for using the internal speakers, or the internal
microphone.  It defaults to the non-existent dock speakers and
microphone every time I reboot.

The only way I could get the internal microphone to work was if I booted
without being attached to the dock, then attach the dock after I logged
in.
