[Dandromb <1478781@xxxxxxxxxxxxxxxxxx>]

for what it's worth, another solution to the horrific stuttering I
encountered was to change in /etc/pulse/default.pa the line "load-module
module-udev-detect" to "load-module module-udev-detect tsched=0". I am
worried that this negatively impacts performance, or increases CPU or
other resource usage. I am hesitant to recommend that as the default
behavior if it does use more  resources.

Title:
  [Inspiron 1010, Realtek ALC269, Speaker, Internal] Underruns, dropouts
  or crackling sound (ie stuttering audio)

Status in alsa-driver package in Ubuntu:
  New

Bug description:
  steps:

  install a fresh copy of xubuntu (or Ubuntu or Debian . . .)

  watch any html5 video (that was the only kind of video I could find
  without installing flash/nonfree packages.) eg:

  http://www.w3.org/2010/05/video/mediaevents.html (anything from here)
  or
  https://youtu.be/kmk43_2dtn0

  expected outcome:

  clear, stutter-free audio.

  actual outcome:

  horrible stuttering, so bad it makes me worry it might be harming my
  system.

  Thankfully there is a workaround.

  WORKAROUND:

  open the file "/etc/modprobe.d/alsa-base.conf"

  add a line that reads "options snd-hda-intel position_fix=1"

  this fixes the stuttering entirely (except when the CPU is totally
  maxed out; then video and audio stutter together, which is to be
  expected)
