  If users use the latest Dell USB Dock, e.g. TB16, they will found the
  analog audio (lineout jack) can't work under ubuntu linux

  [Test Case]

  After applying the fix, users can play sound via analog speaker or
  lineout freely. Without the fix, users can't play sound from lineout
  jack.

  No any possibility to introduce regression since this fix just adding
  a new dock's support, it does not change any existing code.

  Steps:
  1. Cold boot system with BME/IE connected
  2. Plug in a speaker to Line-out jack
  3. Set Analog Stereo Output from Sound settings
