There are also some messages like "snd_hda_codec_realtek hdaudioC0D0:
Unable to sync register 0x2b8000. -11".

** Description changed:

  If I connect headphones after the system boot or if I boot the system
  with headphone connected and after boot disconnect the headphone without
  reproducing any sound before, the system starts flooding dmesg with
  messages like "snd_hda_intel 0000:00:0e.0: No response from codec,
- resetting bus: last cmd=0x01470500". If I boot the system and reproduce
- any sound before disconnecting headphone, everything works normally.
+ resetting bus: last cmd=0x01470500" and becomes very slow. If I boot the
+ system and reproduce any sound before disconnecting headphone,
+ everything works normally.
