    Sound Crackling

    I turned on my computer today to find that the sound has stopped working correctly, all it does is crackle when playing any sound.

    It was fine last night, and i don't think i have changed any settings.

    I have used the sticky guide at the top of the page and it has not worked.

    help

    What do you have your audio config set to? Automatic, ALSA, etc?

    Try and set it from autodetect to ALSA.

    Re: Sound Crackling

    I have exactly the same problem (turned on computer to find sound was cracking), I have tried to change the settings to ALSA but that didn't work.
    Any clues as to what might be going on? Thanks

    Re: Sound Crackling

    Set the sound playback options back to Autodetect. Your problem is most likely because your PCM mixer's volume is muted/set to 0%. Check it via alsamixer:

    Code:
    $ alsamixer -Dhw
    P.S. Searching the forum is always worthwhile. I've replied to similar threads at least half-a-dozen times in the past week.

    Psyke83, thanks for the post, increasing the PCM volume did the trick for me as well... strange bug!
