Title:
  Sound panel in System Settings fails to recognise built-in audio

Status in unity-control-center package in Ubuntu:
  New

Bug description:
  When the system starts up, the sound system sometimes fails to
  recognise the sound hardware correctly.

  One instance is where the System Settings > Sound window shows the
  Speakers, Built-in Audio in the Play Sound Through window but shows
  the settings for HDMI / Display Port instead. It is necessary to click
  on the Speakers in order to get the correct Settings for Speakers to
  be displayed.

  What the System Settings needs is a link to PulseAudio Volume Control
  which provides more options for selecting the various sound channels
  and options available e.g. Speakers, HDMI / Display Port or Bluetooth.
  This app is not necessarily known to the uninitiated. Perhaps some of
  its functionality needs to be included in the Sound window selected
  from System Settings.
