[Doug Holton <1289930@xxxxxxxxxxxxxxxxxx>]

I still see the issue with a brand new dell xps 13 9333 and ubuntu 14.04
just installed fresh.

One temporary workaround (works only a few minutes) is to close the lid
and put the system to sleep.  When waking back up, sounds play without
the crackling/popping/clicking noises for a short while.

Title:
  Crackling sounds after rebooting, and when playing any audio. Going to
  sleep and coming back fixes it.

Status in “alsa-driver” package in Ubuntu:
  Confirmed

Bug description:
  Hi folks!

  I'm using Ubuntu 12.04 on a Dell XPS 13 developer edition, and the
  sound has a problem out of the box. I hear crackling noises whenever I
  play any sort of music (from the test sound in the settings to Youtube
  videos).

  I've been looking on forums to find a working solution, but none of
  them has worked yet.

  I have Alsa 1.0.25 installed, and I'm pretty sure my system info is
  sent along with this bug report. Feel free to reach out if you have
  more questions.

  Thanks a lot!
