Script to mute laptop when suspend button is pressed

Question

I am wanting to make my laptop mute its sound when I suspend, as well as hibernate. I have attempted this by writing a simple script and placing it in my /etc/pm/sleep.d folder and making the script executable. However when I suspend my laptop nothing happens. Can someone tell me what I need to do to make this goal of mine to work?

#!/bin/bash
#script to make  system mute sound on  suspend


    amixer -q -D pulse sset Master toggle

sleep.d scripts must have quite strict names and structure.... See if http://askubuntu.com/a/436389/16395 helps for hints — Rmano, Oct 25 '15 at 08:03
So then would this be what you are talking about then? http://paste.ubuntu.com/12941216/ — philipballew, Oct 25 '15 at 08:30

Here's how the script in /etc/pm/sleep.d should look like. Name it 20_mute_audio

#! /bin/sh
case $1 in
     suspend|suspend_hybrid|hibernate)
         amixer -q -D pulse sset Master toggle
        ;;
esac

Probably --- although I will use "mute" instead of toggle (you never know your status when entering there). And remember to chmod +x the script, otherwise it will not executed. – Rmano Oct 25 '15 at 19:24
This is not working for me. I'm using 17.10. – Miladiouss Feb 12 '18 at 09:59
Try placing it in /lib/systemd/system-sleep/ – dfsg76 Dec 24 '19 at 07:58
