http://ubuntuforums.org – After upgrading to 12.10, i'm getting a loud beep when shutting down or restarting my HP 2560p laptop. Sound comes through speakers and/or headphones. This happens on unity and gnome DE. hwinfo --sound shows the following: Code: 12: PCI 1b.0: 0403 Audio device [Created at pci.318] Unique ID: u1Nb.kZ5ZvXzaJL4 SysFS ID: /devices/pci0000:00/0000:00:1b.0 SysFS BusID: 0000:00:1b.0 Hardware Class: sound Model: "Intel Audio device" (Hardware)
