This is an overview of how I configured my system to play a sound when a USB device (such as a flash drive) is plugged in.

Requirements

• Linux install with udev and systemd.
• Root access.
• A utility to play sounds (I used aplay).
• Sounds to play.

Playing a sound

Using the tool aplay (found in the Arch package alsa-utils), it is easy to play an audio file: aplay insert.wav
