Title:
  Laptop headphones stopped working after updating system

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When I applied updates installing linux-image-3.2.0-65-generic, the
  laptop headphones (sound system) stopped working.  When I pull out the
  sound-system plug, sound works through the (pathetic) laptop speakers.
  Sound is at a reasonable level, and is not muted.

  When I reboot with the former system linux-image-3.2.0-61-generic,
  sound works through the speaker system as it always did before.

  I am using an Acer Aspire 4339, running Ubuntu (Unity) 12.04.

  I expected sound (audio) to continue working through my sound system
  after applying system updates, but it didn't.  The only way to get any
  sound is to use the laptop speakers.
