HPLaptop Mic Mute Button LED Always On - Linux Beginner's Issue

Mic Mute Button with Orange LED - Always On for Linux Beginners

This article aims to help Linux beginners understand how to make the mic mute button on their HP laptop display an orange LED when muted, regardless of the system settings. This can be particularly useful for those who rely on visual cues to manage their audio input.

Background

The mic mute button on many HP laptops comes with an LED indicator. By default, the LED turns red when the microphone is muted. However, some users may prefer an orange LED to differentiate between muted and unmuted states more easily. Unfortunately, there is no straightforward way to change the LED color using the standard system settings.

Solution

To achieve this, we will use a simple shell script that toggles the microphone mute status and sets the LED to the desired color. We will use the amixer and ledctl tools for this task.

Requirements

To follow this guide, you need:

• An HP laptop with a mic mute button and an orange LED
• Linux distribution installed
• The amixer and ledctl tools installed

You can install the required tools using your distribution's package manager:

 Ubuntu/Debian:
 sudo apt-get install amixer ledctl
 

Fedora: sudo dnf install alsamixer pactl ledctl

Setup

First, create a new shell script named mic-mute.sh in your home directory:

 touch ~/mic-mute.sh
 

Now, open the script in your favorite text editor:

 nano ~/mic-mute.sh
 

Add the following content to the script:

 #!/bin/bash
 # Toggle microphone mute status
 if [ "$(amixer get Master | grep 'Mono: Playback' | awk '{print $3}')" = "on" ]; then
 amixer set Master toggle
 ledctl on --device-name "mic-mute" --color orange
 else
 amixer set Master toggle
 ledctl off --device-name "mic-mute"
 fi
 

Save and close the file.

Next, make the script executable:

 chmod +x ~/mic-mute.sh
 

Usage

Now, you can use the script to toggle the mic mute status and LED color:

 ~/mic-mute.sh
 

The script will toggle the microphone mute status and change the LED color accordingly.
