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

I want to make my speakers and headphone jack automatically mute when I return from hibernation/suspend, or maybe mute right before I hibernate/suspend.
