How to mute volume on every boot in Kubuntu 18.04?

  • 772

I want to set the speaker and microphone volume to zero or mute them every time my laptop starts, even if the last time I shut down my computer they where not muted. Just like what Kali Linux does. Thanks in advanced.

boot kubuntu mute

  1. This answer from stack exchange should do the trick: Set Ubuntu Sound Volume on boot

    From the question you want to use this command:

    `/usr/bin/amixer -c 0 sset Master,0 0% > /dev/null`

    From the answer you want to add the command in:

    /etc/rc.local

    Insert the command after the first line and before the last line:

    #!/bin/sh    # <---- This is the first line

`/usr/bin/amixer -c 0 sset Master,0 0% > /dev/null`

exit 0       # <---- This is the last line

    In my Ubuntu 16.04 LTS sound is already muted on boot. This happens to others as well: How to make my microphone unmuted on startup?

    Check the file /etc/modprobe.d/alsa-base.conf and look for the line:

    options snd-hda-intel model=auto enable=yes

    If it exists either delete it or put # in the first character position.
