Luke Yelavich : Unfortunately, sudo /etc/init.d/alsa-utils reset pcsp did not fix the problem for me. However, I did have PC Speaker volume set in gnome-mixer-applet. Setting to mute fix the problem. Should we consider the crackling sound at boot as a bug when PC Speakers are not set to mute? IMO, yes, but I might be wrong.
