Hi there,
this post is related to this old thread [1]](http://forums.opensuse.org/english/get-technical-help-here/laptop/458643-cracking-sound-trough-speakers.html) and this old bug report [2]](https://bugzilla.novell.com/show_bug.cgi?id=697187) which where fixed in time by installing 12.1.
However, after yesterday’s updates I booted my laptop today to find out that the annoying cracking sound is back.
I looked at the logs and these are the updates from yesterday’s “zypper dup”

I tried changing /etc/modprobe.d/50-sound.conf as suggested but did not help

Any other ideas and/or suggestions? Could it really be pm-utils related?
I will also file a bug and post the number here.
Thanks!
