patch_analog.c related to ad1986a?


some laptop seem to use 3stack instead of laptop model in the past since the mic select is quite complicated

Title:
  Easynote MX65, AD1986A, No sound output in speakers/headphones, some
  with tricks

Status in “alsa-driver” package in Ubuntu:
  Incomplete

Bug description:
  I have a fresh install of KUbuntu 14.10 with this problem and i come
  of a KUbuntu 13.10 without problems.

  I don't have any sound from speakers or headphone, i think the driver
  isn't loaded, but the microphone works, it records. The sound playback
  works too, but the sound doesn't go through speakers or headphones.

  I was testing with a lot of LiveCD KUbuntu when the problem comes.
  With LiveCDs KUbuntu 12.04.5 LTS, 12.10, 13.04 the sound works, they
  configs the sound system as "HDA Intel AD198x". Since LiveCDs 13.10,
  14.04.1 LTS and, of course, 14.10 Live CD and my install, i have this
  problem, because the sound system is now "AD1986A". I will attach the
  alsa-info output for all this systems in my computer.

  But with HDA_Analyzer http://www.alsa-
  project.org/main/index.php/HDA_Analyzer i found the details of the
  problem: i can create a python script to brought back the sound
  working in a basic mode, like as previously. The details are
  activating EAPD in Card 0, Codec 0, Node 0x1b PIN (In my computer, it
  could be different in another) what brought back the sound to the
  speakers, and unmuting "Output Amplifier" in Card 0, Codec 0, Node
  0x1a VAL[0] and VAL[1] to brought back sound to the headphones when
  they are plugged. I will attach too the output of this diff and the
  python script created by HDA_Analyzer for my system.

  At least, the basic working state should be back, because with a
  untoching fresh install there isn't any sound. There are related bugs
  here and other post in internet, but i collected all information i
  found and can give more if it's necessary.

  For additional information: Searching the solution, i tested too all
  the models availables for HDA Intel AD1986A (editing /etc/modprobe.d
  /alsa-base.conf with AD1986A models /usr/share/doc/alsa-base/driver
  /HD-Audio-Models.txt.gz) and i found the default one doesn't fit my
  system and anothers are better, but have problems of no sound too and
  i don't found how to fix these problem. When this bug is corrected, i
  want to help to found a better model for my computer, i don't know how
  now, but first it brought back the sound. Also, i test with snd-hda-
  tools https://launchpad.net/~diwic/+archive/ubuntu/hda and with hda-
  jack-sense-test the Green Line Out sense doesn't work (always NO
  present) but the Pink Mic sense works without problems.
