Title:
  [Dell L521X, ALC3260]No sound through headphones after boot

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  After Ubuntu boots, randomly (say with 25% probability) the Headphone
  alsamixer setting will be muted and set to 0 on my notebook. The
  notebook will not play any sounds on headphones, only through the
  notebook speakers when headphones are disconnected. I then have to
  manually run alsamixer, unmute the Headphone setting and max it out to
  100. This started to happen after upgrade to Ubuntu 15.10 - Ubuntu
  15.04 worked fine.
