[Bug 2121815] Re: Internal microphone works with 6.11.0-17 kernel. It does not work with 6.14.0-29.

  Thread Previous • Date Previous • • Thread Next 
For 6.14.0-29 kernel boot there is additional line printed:
"snd_hda_codec_realtek hdaudioC0D0: ALC256: picked fixup  (pin match)"
Also different order during initialization, irg, pm_blackjlist value and other.

Title:
  Internal microphone works with 6.11.0-17 kernel. It does not work with
  6.14.0-29.

Status in alsa-driver package in Ubuntu:
  New
Status in linux package in Ubuntu:
  New

Bug description:
  I installed Ubuntu Desktop 24.04_02. With kernel 6.11.0-17 internal
  microphone works. After upgrade to 6.14.0-27 and later 6.14.0-29 it
  does not. I preserved 6.11.0-17 and when I boot it once again
  microphone is working again. There are no any sound configuration
  changes except kernel boot.
