Public bug reported:
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" and becomes very slow. If I boot the
system and reproduce any sound before disconnecting headphone,
everything works normally.
