I just encountered this bug for the first time after upgrading from
12.04 to 14.04.  My old Turtle Beach Santa Cruz card worked fine before,
but after the upgrade I started to get distortion and crackling.

hoocker's suggestion in #96 seems to have fixed it!  Or at least,
greatly reduced it.  Thanks much!

Title:
  [cs46xx] Need tweaks to daemon.conf to eliminate crackle/distortion

Status in “linux” package in Ubuntu:
  Invalid
Status in “pulseaudio” package in Ubuntu:
  Confirmed

Bug description:
  Ever since the pulseaudio updates on 9/11 (1:0.9.16-0ubuntu1, see
  http://changelogs.ubuntu.com/changelogs/pool/main/p/pulseaudio/pulseaudio_0.9.16-0ubuntu1/changelog),
  I've had crackling or distortion on the audio output. Audio was
  perfect prior to that update.

  The output will vary from normal, to crackling, to distorted, to the
  stuck "machine-gun" sound if and only if I change the audio volume up
  and down. This is the same across all sound sources.

  Audio card is cs46xx based hercules game theater XP. Running latest
  Karmic.
