** Description changed:
Every time I plug headphones to my laptop (while using battery) it
immediately powers off. I can only recognize the window saying: "unknown
audio device", and suggesting choice: "headphones", "headset" and
"microphone". However it works fine, when laptop is plugged with AC
adapter. But when I close laptop with both AC adapter and headphones
plugged in, instead of going to sleepmode it powers off.
I have googled the solution to disable Intel Audio power saving mode by
editing /usr/lib/pm-utils/power.d/intel-audio-powersave.
#INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
INTEL_AUDIO_POWERSAVE=false
But it didn't help. Laptop still powers off.
I have checked syslog for exact time when I plugged headphones, but didn't
found any recordings.
I am using Ubuntu 16.04.
My laptop: Dell Inspiron 5559
My headphones: Sound Intone E6

+ update: It helped to disable TLP to get rid of this bug. So, now when I
+ plug the headphones the laptop does not shut down. However, when I close
+ my laptop instead of going to sleep mode it shuts down. So disabling TLP
+ did not help to get rid of this bug completely.
