Moreover, PowerShell can leverage Part Object Mannequin (COM) objects to work together immediately with the Home windows audio system.
Linux: Linux techniques sometimes use Bash or Zsh as their command-line shells. Two frequent utilities for audio management in Linux are amixer and pactl. amixer is a part of the Superior Linux Sound Structure (ALSA) and supplies a low-level interface to the audio {hardware}. pactl, alternatively, is a part of PulseAudio, a sound server that gives extra superior options resembling community audio and stream administration.
macOS: macOS makes use of the Terminal software as its command-line interface. Whereas macOS does not have a devoted audio management utility like amixer or pactl, it supplies osascript, a command-line device for executing AppleScript code. AppleScript means that you can work together with the working system and management varied elements of the system, together with audio quantity and muting. The afplay command can even have system quantity results.
These utilities work together with the audio system by sending instructions to the underlying audio drivers or sound servers. For instance, amixer immediately manipulates the mixer controls of the ALSA driver, whereas pactl communicates with the PulseAudio server to regulate audio streams and units. Understanding this interplay is essential for troubleshooting points and customizing your audio management setup.
Muting Sound with Command on Home windows
Home windows supplies a number of methods to mute sound from the command line. We’ll discover two fashionable strategies: utilizing nircmd and utilizing PowerShell.

nircmd is a free and moveable command-line utility that gives a variety of system administration features. To make use of nircmd for audio management, you first have to obtain it from the official web site and extract the executable file to a listing in your system’s PATH. As soon as nircmd is put in, you should use the next command to mute the default audio machine:
nircmd muteappvolume "System Sounds" one
To unmute the audio, merely substitute one with zero:
nircmd muteappvolume "System Sounds" zero
You can even mute particular purposes by changing “System Sounds” with the title of the appliance. For instance, to mute “Google Chrome,” you’ll use the next command:
nircmd muteappvolume "chrome.exe" one
Keep in mind to make use of the proper course of title of the appliance.
Utilizing PowerShell
PowerShell affords a extra built-in option to management audio utilizing Part Object Mannequin (COM) objects. The next PowerShell script can be utilized to mute the default audio machine:
$MMDeviceEnumerator = New-Object -ComObject MMDeviceAPI.MMDeviceEnumerator
$DefaultAudioEndpoint = $MMDeviceEnumerator.GetDefaultAudioEndpoint("Render", "Multimedia")
$DefaultAudioEndpoint.AudioEndpointVolume.Mute = $true
To unmute the audio, substitute $true with $false:
$MMDeviceEnumerator = New-Object -ComObject MMDeviceAPI.MMDeviceEnumerator
$DefaultAudioEndpoint = $MMDeviceEnumerator.GetDefaultAudioEndpoint("Render", "Multimedia")
$DefaultAudioEndpoint.AudioEndpointVolume.Mute = $false
You’ll be able to adapt this script to mute particular purposes by figuring out the proper audio session and setting its mute property.
You’ll be able to create batch information or PowerShell scripts containing these instructions to simply mute and unmute your system with a single click on.
Muting Sound with Command on Linux
Linux affords two main utilities for audio management: amixer and pactl.
Utilizing amixer
amixer is a command-line mixer that means that you can management the amount and mute standing of varied audio channels. To mute the Grasp channel utilizing amixer, use the next command:
amixer -D pulse set Grasp mute
To unmute the audio, use the next command:
amixer -D pulse set Grasp unmute
Be aware that the channel title may differ relying in your system configuration. You should utilize the amixer scontrols command to listing the obtainable mixer controls and determine the proper channel to mute. The -D pulse argument specifies utilizing the PulseAudio sound server. Omit for ALSA.
Utilizing pactl
pactl is a command-line device for controlling PulseAudio. To mute the default sink (audio output machine) utilizing pactl, use the next command:
pactl set-sink-mute @DEFAULT_SINK@ toggle
This command toggles the mute standing of the default sink. You can even use true or false as an alternative of toggle to explicitly mute or unmute the audio.
To mute a selected audio output, you must determine its sink ID. You should utilize the pactl listing sinks command to listing all obtainable sinks and their corresponding IDs.
You’ll be able to create shell scripts or aliases for these instructions to make them simpler to make use of. For instance, you possibly can create an alias referred to as mute that executes the pactl set-sink-mute @DEFAULT_SINK@ toggle command.
Muting Sound with Command on macOS
macOS primarily depends on AppleScript for command-line audio management.
Utilizing osascript with AppleScript
osascript means that you can execute AppleScript code from the command line. To mute the system quantity utilizing AppleScript, use the next command:
osascript -e 'set quantity output muted true'
This command units the output quantity to muted. To unmute the audio, use the next command:
osascript -e 'set quantity output muted false'
This strategy supplies a easy and efficient option to management the system quantity from the command line.
You’ll be able to create Automator providers or shell scripts that execute these instructions to offer even simpler entry to mute performance. A easy shell script may seem like this:
#!/bin/bash
