I have installed Kubuntu Edgy from scratch and the problem happens too with the fresh install. I've found this post:
http://ubuntuforums.org/showpost.php?p=1647699&postcount=349 that describes the same problem. Since kdm doesn't make a sound when presenting the login screen, the problem is unnoticed until after login. Please advice on what hardware reports would be meaningful. -- Repeating broken sound after Dapper -> Edgy beta update https://launchpad.net/bugs/63388 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
