Comment 81 for bug 486154

To re-enable the terminal bell on my ThinkPad X61 running Ubuntu 10.10 I took the following actions suggested above:
    * Un-blacklist pcspkr as described above, then either reboot or modprobe pcspkr.
    * On the terminal window, tick "Edit | Profile Preferences | General | Terminal bell"
    * Run gconf-editor and at "apps | metacity | general" tick audible_bell.
    * Run gconf-editor and at "desktop | gnome | peripherals | keyboard" change "bell_mode" from "off" to "on".
    * Use the alsamixer program to unmute and raise Beep volume to a suitably high level.
    * Do pactl upload-sample /usr/share/sounds/ubuntu/stereo/bell.ogg bell.ogg
