[Bug 52649] Re: After installing the latest Linux kernel with Update Manager, Gnome start not normal.

[Peter Belew]

This indeed looks like a duplicate to bug#53207. I'm using a Jetway
625EMP800 motherboard on the system I have the problem with. Disabling
sound for a particular user by taking that user out of the audio group
keeps the repeated sound (and any sound!) from happening, but the
drumming or repeated sound still happens when the login screen is up.

(Also the default screensaver hangs the system - that may be related -
I'll have to investigate that later on.)
