Question: The [ping manual](http://manpages.ubuntu.com/manpages/maverick/en/man8/ping.8.html) says that `ping -a` will generate audible pings, but when I try this no sound is made.

What am I doing wrong?

Answer: 
[1](https://www.richud.com/wiki/Ubuntu_Beep_Audible_Bell_Ping_Fix) says it's missing a sound file. You can add it with the following command:

```
  pactl upload-sample /usr/share/sounds/gnome/default/alerts/glass.ogg bell.ogg

```

For a permanent solution add the command to ~/.xprofile
If you are using Terminator as terminal on Ubuntu 18.10, left-click the Terminator, select preferences/profiles, and there is the audible beep option.
