VLC’s sound is crackling

Under Ubuntu, when playing a movie with VLC, I hear some crackling. The audio output is distorted. With mplayer everything works fine.

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.

    Had an audio issue. I think it’s because of my old hardware, but this works for me. The issue was: “When I trying to run an video, the sound has a chance to configure the output correctly. But randomly, when I jump forward or backward, The sound has a chance to be activated, if it’s not. And also, the sound has a chance to be deactivated, if it’s running. (chance depending on the quality of the video (higher quality – lower chance to hear sound))”. Thanks, that’s fix my problem.

    Hey guys,

    You can try this to fix the audio quality => Go in to the Preferences and switch the Output Module to ALSA audio output. Quit VLC & relaunch.

    Know how to operate your VLC media player just by using the external keyboard? Discover how, click vlc keyboard controls
