Title:
  5.1 built-in surround detected as 4.0 on Acer Aspire 8943G with ALC670

Status in ALSA driver:
  Unknown
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After fresh installation even stereo configuration is set. From the
  menu can be selected 4.0 configuration making the rear left and right
  speakers work, however, front center and LFE (subwoofer) do not emit
  any sound in any application. They can be only tested (and they are
  working within this command) by `speaker-test -D default -c6 -twav`.
