    Yay! That was frustrating and I couldn’t find help on my list visit to ubuntuforums.

    Also used commenting instead of deleting.

    That doesn’t work for me. When I comment the lines out nothing changes and when I delete the lines the crackling noise disappear but the rest of the sound too.

    my mind was confusing

  15. swedish_chef says:

    If you don’t want to reboot you may also restart the alsa driver like this

    sudo /etc/init.d/alsa-utils stop

    sudo alsa force-reload

    sudo /etc/init.d/alsa-utils start

    Klart, no reboot required =)

    Thanks, it worked for me. The annoying sound is gone now. Good job.

  18. Live says:

    Oh my shomai! How can we spread the word? This is working!

  19. I suggest you comment out the lines rather than deleting. If the fix doesn’t work and the user wan’t to roll back then there is no rollback path if the text is deleted.
