Title:
  1412:1712 Crackling Sound on PCI card

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  On my CyberpowerPC Gamer Xtreme 1030 desktop running up-to-date Natty
  Narwhal 64bit on fresh install, there is a variable crackling
  overlaying the sound on my card when any sound is playing. It is
  invariable to the output, as looping the same clip does not cause
  crackling to loop. The output of sudo aplay -l is:

  card 0: M1010LT [M Audio Delta 1010LT], device 0: ICE1712 multi [ICE1712 multi]
    Subdevices: 1/1
    Subdevice #0: subdevice #0

  Any idea's on what this is? Occurs with pulseaudio on or off (even
  with speaker-test), and only on my Delta 1010LT sound card. Jaunty
  livecd plays audio without crackles, while Natty livecd produces
  crackles.

  WORKAROUND: nohz=off
