    Loud Beep on speakers when rebooting/shutdown

    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"
      Vendor: pci 0x8086 "Intel Corporation"
      Device: pci 0x1c20 
      SubVendor: pci 0x103c "Hewlett-Packard Company"
      SubDevice: pci 0x162b 
      Revision: 0x04
      Driver: "snd_hda_intel"
      Driver Modules: "snd_hda_intel"
      Memory Range: 0xd4700000-0xd4703fff (rw,non-prefetchable)
      IRQ: 47 (918 events)
      Module Alias: "pci:v00008086d00001C20sv0000103Csd0000162Bbc04sc03i00"
      Driver Info #0:
        Driver Status: snd_hda_intel is active
        Driver Activation Cmd: "modprobe snd_hda_intel"
      Config Status: cfg=new, avail=yes, need=no, active=unknown
    Already tried every solution found here to no avail:
    https://bugs.launchpad.net/ubuntu/+s...ux/+bug/331589

    Which include disabling sound notification on "sound" config, blacklisting pcspkr, going to alsamixer and lowering "Beep" to 0, etc etc..

    Audio is working 100% btw, although this Model: "Intel Audio device" is suspiciuous.. maybe my system is not fully recognizing my onboard audio?

    Also, i can't set any notification sound on the "sound" configuration panel, they're all greyed out, even when i enable it.

    Re: Loud Beep on speakers when rebooting/shutdown

    Problem solved. After trying the above, and also reinstalling the whole audio framework, and using alsamixer on console, i came across the gnome-alsamixer package. Using this software i was able to find a "Beep" entry which i disabled, muted, and lowered volume to 0, three times just to make sure. Problem got solved.

    So, for anyone having similar issues, use GNOME-ALSAMIXER.
