I could test this problem with 4.0 kernel, but I'm on 14.04, and there is no 4.0 kernel for this version.
Will http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-rc5-vivid/ even work?

** Tags added: apport-collected

** Description changed:

  Combo jack (headphones and microphone) working only as headphone output.
  Microphone is not detected at all when plugged-in.
  
  My exact laptop model is: Dell XPS 15 9530.
  
  I'm on 14.04 LTS, but I dont think its version-related. What more
  informations shall I collect and post here?
  
  I have also sent a report via http://www.alsa-project.org/alsa-info.sh.
  Would it help if I include one here?
