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

    Also used commenting instead of deleting.

  2. 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.

  3. Het man thank you for adding the credits, i didnt know that it would help THAT many people. I really do appreciate it. this is linuxgeek77 from the ubuntu forums post.


  4. You can either comment it out with # or delete it. it is the same concept. I dont like to waste bytes:P so i deleted it.

  5. 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 =)

  6. 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.
