   @ranj063 reported she found same issue in CML chromebook. And Chrome team found suspicious commit.

   I tried to revert the commit id, but looks same to me.
   333ee22 ASoC: SOF: Intel: hda: fix the hda init chip

   I can try git bisect and update the candidate commit here.

   In terms of audio playback in GLK(sof-dev),
   072cf06 Merge pull request #970 from plbossart/merge/broonie-next-20190521 <== bad
   d807d30 ASoC: SOF: Intel: ipc: don't check for HIPCCTL register value <== good

   After git bisect, the result is,
   e57ccca is the first bad commit
   e57ccca (refs/bisect/bad) Merge tag 'sound-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

   This error started from e57ccca

   One more update, I tried today's daily build(20190601, China time), surprisingly it works. For more build info,

   I've seen coupe of CML boot instances failing with same error signature.
   HDMI HDA Codec ehdaudio0D2: HDMI: failed to get afg sub nodes
   HDMI HDA Codec ehdaudio0D2: Failed in parse and map nid with err: -22
   HDMI HDA Codec: probe of ehdaudio0D2 failed with error -22

   Test tried : run reboot script and check card lists everytime after boot. Happens 1 in 10 machines and 1 in 1000 iterations..
