This looks already bad.  It means that power down of the codec
failed.

But, the recent version should ignore this error.  There was a logic
failure to check this, but this was corrected recently.

Could you check the latest 4.0-rc whether it works better?
If not, take alsa-info.sh output snapshots at good and bad working
moments.  Run the script with --no-upload option, and attach the
outputs (better compressed).
