Public bug reported:
This appears to be somewhat related to bug #450122. The same loud
buzzing sound occurs at shutdown and in virtual consoles when the bell
is supposed to occur. This does not happen in the GNOME terminal, you
have to Ctrl+Alt+Fn into a virtual console and perform an action that
causes a bell.
Currently using the latest linux-alsa-driver-modules-2.6.32-22-generic
from the ubuntu-audio-dev ppa.
To reproduce:
1. Ctrl+Alt+F2 into virtual console.
2. Press backspace at the shell to cause the bell.
