Title:
  ubuntu 16.10 internal speakers don't work, but headphones do

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  Under sound settings only headphone output is listed as an option, no
  internal speakers are listed. Headphone playback does work. In
  alsamixer, speaker output was at 0 and muted, but unmuting and
  increasing volume does not produce playback in speakers.
