Title:
  2.1 surround support (userspace)

Status in “alsa-lib” package in Ubuntu:
  Fix Committed
Status in “pulseaudio” package in Ubuntu:
  In Progress

Bug description:
  2.1 surround should work as seamlessly as other surround options, such
  as 4.0, 5.1 and 7.1 work today.

  Alsa-lib and pulseaudio patches for 14.04 can be tested here:
