Title:
  speakers audio won't work - pavucontrol is switching continually
  between speakers and headphones

Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  The port is continually switching between Speakers and Heaphones and no audio is outputting from the speakers. I have tried various distributions and have found that this problems is NOT present in Ubuntu 11.04, 12.04, 13.04. I have not tried 11.10, or 12.10. But have found 13.10 and 14.04 to show this identical problem.
  My main concern is for the 14.04 LTS version I am currently using.

  - I tried regulating the audio from alsamixer -by disabling auto-mute in alsamixer i managed to stop it switching from one port to the other. Still, no audio from speakers (only a regular and low-volume BUMP comes out)
  - I tried modifying the /etc/modprobe.d/alsa-base.conf file. Since i could not find my pc (Packard Bell EasyNote MX45) in the alsa-configuration list, i have tried using only the audio boards main info as referral (Intel HDA AD1986A NM10/ICH7). Thus i have added to the alsa-base.conf the following and rebooted after trying each and every new line (added only once per try, not all of them together).
                    -options snd-hda-intel model=laptop
                    -options snd-hda-intel model=laptop-eapd
                    -options snd-hda-intel model=3stack     
                    -options snd-hda-intel model=generic

  - Also tried the position_fix quirking suggested on the ubuntu documentation pages
                   -options snd-hda-intel position_fix= 1 
                   -options snd-hda-intel position_fix= 2

  The audio outputted from the speakers kept being a regular BUMP and
  nothing more, regardless of the input.
