ConEmu: disable bell

I'm really appreciating conemu as an alternative windows shell, but the alert bell sound is driving me crazy! (I wear earbuds and that sound goes right through me..)

Is there are an option to disable the bell alert noise (or switch for a screen flash or something)?

There is "Suppress bells" option.

It's caused by the terminal, not ConEmu. For example, it doesn't happen in a local terminal in msys (= Git Bash), cmd, or Cygwin (for me). It happens when you ssh into a remote machine (or VM). To fix in Bash you just need to run this command:

set bell-style none

To always turn off the bell in the future, place this command on a line in a file called .inputrc. I think it will also work in .bashrc. You can do this via your text editor of choice or on the command line with:

echo "set bell-style none" > .inputrc

Of course, you'll need to do this whenever you get to a new machine that does this. You can turn it off globally in /etc/inputrc. You can also set the bell style to 'visible' instead of 'none' to make the terminal flash.

There are other ways to turn off the bell in other shells and programs: http://www.tldp.org/HOWTO/Visual-Bell-8.html

A simple solution is to go to the Volume Mixer and set the volume for "Console Window Host" to 0. This will prevent any console from making any sounds at all. But in practice the only sound it makes is that horrible bell and this will silence it.

In Windows 7+ this sound is played by the Bell driver. In Windows 10 at least, you can change the sound it makes by using the Sound control panel to alter the noise it makes for the Critical Stop event. I found Windows Ding was a better choice for ConEmu, no idea what other apps might play that sound.
