Title:
  [SB-XFi - Creative X-Fi, playback] Background noise and Distortion

Status in alsa-driver package in Ubuntu:
  Expired

Bug description:
  Recently upgraded to Kubuntu 12.10 x86_64. Was previously using 11.10
  x86 (32 bit) and no problems with sound. Now sound is very glitchy,
  distorted and even has a warbling delayed echo.

  Tried all maner of Pulse Audio stuff like changing sampling frequency
  in /etc/pulse/daemon.conf and timer scheduling in
  /etc/pulse/default.pa.

  Tested with Pulse Audio suspended and using Jack and the problem
  persisted which makes me think it may be driver related (not pa) -
  possibly 64 bit version as I had no problems with 32 bit.

  Kubuntu 12.10
  uname: Linux 3.5.0-17-generic x86_64

  Alsa version 1.0.25
