I have a working script that mutes my sound. The script is:

amixer -q -D pulse sset Master mute

I want to let this script run on shutdown and reboot so that when I turn on my PC, the sound is muted. If I run this script manually before shutdown/reboot, then it works and my sound gets muted and is muted on startup.

However, I can't get it to run automatically. I have tried shutdown, reboot and startup seperately using this guide.

For shutdown I tried editing /etc/rc6.d. For reboot I tried putting my script in /etc/rc0.d. for startup I tried editing /etc/rc.local.

Does someone know the solution?

Thanks :) !

PS: The reason for this is that my thinkpad laptop make a loud popping noise from the speaker at startup and this is prevented by starting it up muted.
