[Bug 996906]

 

Also, when CPU is loaded for any reason I sometimes get this:

Title:
  periodic audio skips with Intel HDA

Status in PulseAudio sound server:
  Confirmed
Status in pulseaudio package in Ubuntu:
  Confirmed

Bug description:
  When running PulseAudio, if I'm playing music via any source (Exaile, Totem,
  Flash in Firefox or Chromium, VLC, etc.) every few minutes the audio will skip
  once or twice.  top doesn't show any process eating CPU any more when it
  happens.  dmesg doesn't show anything.  Nothing else seems to be affected.  It
  doesn't seem to happen regularly.

  I just installed Ubuntu 12.04 from scratch (with pulseaudio 1:1.1-0ubuntu15),
  but the same thing happened in 10.04 on the same hardware.  Uninstalling the
  PulseAudio packages and going back to ALSA gives me no issues whatsoever, which
  is how I know the issue is with PulseAudio.  I'm using my onboard audio device:

  $ lspci | grep Audio
  00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel
  HDA)

  Following mailing list instructions, pulseaudio -vvvv --log-time shows during a
  skip:

  time.
