The answer given by Wouter works better overall once set up, but it can be slightly confusing to get working as the correct option doesn’t always appear. Follow these steps:
Clic droit the volume control in the Windows taskbar
Ouvrez le Volume Mixer
Ouvrez le Bash on Windows console
Do something to trigger the console making the notification sound (e.g. press backspace on an empty line). If you’ve disabled the notification using the alternative method below, you’ll have to undo it.
Now a Console Window Host option should have appeared in the Volume Mixer (you might have to scroll right)
Mute its sound setting
Previous/alternative method
Vous pouvez simply run la commande suivante from within your Windows Bash shell [source]:
echo "set bell-style none" >> ~/.inputrc
or else edit .inputrc manually with a text-editor to add set bell-style none on it’s own line.
Vous devrez restart your currently open bash shell before it takes affect.
Cela va only work for your current user, and won’t help if you ssh into other accounts (unless you run that command again for each account).
