Title:
  Acer Aspire 5 issue when headphone plug in before login

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  Acer Aspire A515-56-57XR with ALC255 when headphone is plugged in before 
login causes few issues. I will list them below:
  - When headphones are plugged in and if I restart/shutdown-turn on the laptop 
and log in it does not detect headphones microphone at all and internal 
microphone is selected by default.
  - For output device headphones are plugged in but left/right channel is 
merged into both channels
  - To fix this need to re-plug the headphones/earphones and the issue goes 
away or after a restart/shutdown plug in only after logging in.
  - This issue does not occur when log off and log in only after a restart or 
cold boot from a shutdown while headphones/earphones are left plugged in.

  In another similar thread to this lots of other issues were fixed and they 
have been already merged into official kernel now. I will put a link to it 
below for reference. Looking to fix this issue now.
