VLC’s sound is crackling
Problem
Under Ubuntu, when playing a movie with VLC, I hear some crackling. The audio output is distorted. With mplayer everything works fine.
Solution
I found the solution here. This problem is caused by pulseaudio. Start VLC, then go to Tools -> Preferences -> Audio, and change the Output module from the default to ALSA. The distortion went away.
Note that I have Ubuntu on several machines and I had this problem on one machine only.

I had a very similar issue and somehow simply adjusting my volume by one notch (either direction) cleared up the issue- but this was not overdrive crackling but more of a bitcrush sort of distortion, as if a buffer’s offset wasn’t aligning properly or bits weren’t being processed in the right order. There was also a mysterious echo effect with the crush sound.
I followed you advice above and it got rid of my crackling on ubuntu’s vlc. Thanks very much!
Now check out the rest of my blog. It’s full of good advices :D
