tty terminal Ctrl+Alt+F1 - silence the beep:
Here (as root) I created a file named
/etc/profile.d/beep-pcspkr-pcbeep-disable.shand included a setterm command.
Permissions of 644 work okay for this file.
What you should now experience is a TTY console having no beep.
Switch to a tty console login using Ctrl+Alt+F1 and login, your shell completion should now be free of any audible feedback beep.
X terminal - xfce4 terminal - silence the beep:
Graphical desktops (X based) have their own preferences for audio feedback beep, and in my terminal xfce4-terminal, the preference is shown below:
...which can be found in the file
But my MiscBell=TRUE?
Change it to FALSE using an editor if you want to silence the beep.
But my user does not have a file
.config/Terminal/terminalrc- does not exist?
Xfce4-terminal has a preferences screen in Edit->Preferences, go into there and change 'initial title' from Terminal to Xfce4terminal and select 'Close'
What your action above did, was trigger the creation of

Why would you want a beep anyway?
Some command line novices find the audible beep a useful feedback mechanism.
Being a novice, back before Red Hat became Red Hat Enterprise Linux, I remember using the feature myself.
But I still have a bootup and reboot Beep - absolute silence please?
Mute the 'PC Beep' column in alsamixer using the 'm' key.
- Startup alsamixer from a terminal (not required to be root)
- Navigate right until the PC beep column is highlighted
- Press 'm' to mute that column
There is no need to explicitly save alsa settings, as simply exiting using Esc is enough to make your new settings persistent.
Note: PC Beep '00' is probably not going to be complete silence. Mute the thing.
Notes and Further Reading:

- Soundcard testing guide [ alsa-project.org ]
The alsa-utils package contains the program alsamixer. The package alsa-utils should already be installed on your system. If not use the following:
apt-get install alsa-utils
( apt-get above is for Debian and derivatives including Ubuntu)
yum install -y alsa-utils
( yum for Fedora / Red Hat / MeeGo and similar )
That alsa-utils package includes a utility named aplay, which can be used to check which sound devices in your system are known to alsa.
The above is a Dell Inspiron 1525 laptop, which I am currently setting up with Debian Squeeze. This laptop will have an Xfce desktop, and I have yet to test HDMI audio output, as HDMI port is not something I use regularly.
