Title:
  crackling, popping, clicking in playback to audigy2 surround51 device

Status in “alsa-driver” package in Ubuntu:
  New

Bug description:
  After upgrading from Xubuntu 13.04 to 13.10, I hear lots of popping
  (aka crackle, click noises) during playback to my Audigy2 surround51
  device.  This was never a problem before the upgrade.  The noises do
  not show up if I use the card's default, front, or rear devices
  instead, but those leave me without surround sound, so they're no good
  for movie playback.

  The same problem shows up on the surround40 device.  I haven't tried
  the other surround* devices.

  I can reproduce problem in Totem or gst-launch playbin with an .asoundrc containing this:
  pcm.!default {
      type plug
      slave.pcm "surround51"
  }

  I can reproduce problem in Exaile with the custom sink pipeline set to
  "alsasink device=surround51" and no .asoundrc.

  I'm running the amd64 build of Xubuntu.

  My Audigy2 has the first alsa sound card slot, making it my default
  sound card.

  I am not using PulseAudio.
