Title:
  [Alienware Area-51 R2, Creative CA0132, Green Line Out, Rear] No sound
  at all

Status in alsa-driver package in Ubuntu:
  Incomplete

Bug description:
  Description:	Ubuntu 15.04
  Release:	15.04

  
  This is a 5.1 surround sound set up. No output from any speaker. Sound settings configuration doesn't show proper options for this card - no channel info except for analog stereo and S/PDIF outputs where I would expect to see information on Front/Rear/Center speaker outputs.

  Output from aplay -l:
