Title:
  [SB-XFi - Creative X-Fi, playback] Sound is distorted -- (Echo with
  garble)

Status in alsa-driver package in Ubuntu:
  Expired

Bug description:
  This happens in many applications, but most often happens when using
  Orca Screen Reader.  The sound will be fine for a moment then start
  echoing with distortion.

  For instance, the "Welcome to Orca" will say:  "We We Wefds
  Wefdsalcome t t t05432o O Ordsa ORcadsa ORca fssgdsgdfas", where
  random characters are the garble.  It is important to note that this
  is compressed into near the original time-frame of the original sound,
  so it is near impossible to pick out what is being heard.

  When this happens, although it seems certain conditions trigger it, it
  is system wide.  Everything will have that horribly distorted echo.
