Title:
  no sound from speakers, only headphones

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  Sound comes out of the headphones when I insert the jack, but does NOT
  come out of the speakers when I unplug it. This includes sound from
  any source, including aplay.

  This is a newly installed Lubuntu daily build (Lubuntu 15.10 "Wily
  Werewolf" - Alpha i386 20151017.1). If I go back to running from the
  Live USB install media, the sound works fine from the speakers OR the
  headphones, as expected.

  As suggested by https://help.ubuntu.com/community/SoundTroubleshootingProcedure I have tried:
  * killing and reloading pulseaudio and alsa-mixer 
  * purging (.config/) .pulse/ then killing/reloading and rebooting
  * installing and reinstalling pavucontrol linux-sound-base alsa-base alsa-utils libasound2

  In the installed version I notice that in Volume Control (pavucontrol)
  the output switches automatically between headphones and speaker when
  the jack is plugged and unplugged - as one would expect - and in
  alsamixer I can see the inactive device being muted automatically.
  However the speaker never issues any sound :(  On the contrary in the
  live usb I notice that alsamixer leaves both outputs active (unmuted)
  and simply relies on the microswitch in the headphone jack to control
  whether the speaker can be heard or not.

  For reference I past the output of the FAILING test case's alsa-
  info.sh below and attach the output of the WORKING test case's alsa-
  info.sh
