  Lenovo IdeaPad Yoga 13: Inverted Internal microphone (phase inversion)

Status in “linux” package in Ubuntu:
  Fix Committed

Bug description:
  As per this meta-bug:

  Reporting for Lenovo IdeaPad Yoga 13. Inverted channel is visible when
  recording stereo in audacity. Mono recording via pulseaudio gives
  silence with occasional cracks somewhat corresponding to the sound
  level around. Skype and pavucontrol level gauges are also affected.

  Changes in balance in pavucontrol do not help with mono recording, I
  don't know why.

  I'm attaching two patches against oem-audio-hda-daily-
  dkms-0.201310111402~ubuntu13.10.1 (https://launchpad.net/~ubuntu-
  audio-dev/+archive/alsa-daily); either of them fixes the problem for
  me (the -alt one may affect other hardware, though). No additional
  steps were needed after applying a patch, building and installing the

  Output of alsa-info.sh is also attached.
