This fine-grained control ensures that you can tailor your audio experience exactly how you like it without being restricted to the default options offered by standard volume control interfaces.

How to Control System Volume with NirCmd?

Step 1: Download and Set Up NirCmd

To start using NirCmd for controlling your system volume, follow these steps:

Download NirCmd

First, you need to download the NirCmd executable. It’s available for free on the official NirCmd website:

Download NirCmd from NirSoft.

• Click the download link to retrieve the tool. The file is typically small (under 1MB), so it will download quickly.

Extract the NirCmd Executable

NirCmd does not require installation since it’s a portable tool. After downloading the file (typically a .zip archive), extract it to a location on your computer where it’s easy to access. Some suggestions include:

• A dedicated folder for utilities (e.g., C:\Tools\NirCmd).
• Your Desktop for easy access and quick execution.

Simply right-click the downloaded .zip file and select “Extract All” to choose your desired folder.

No Installation Needed

NirCmd is portable; there’s no setup process to follow. After extraction, the nircmd.exe file can be run directly from its folder. You don’t need to go through a traditional installation wizard just place it in a folder, and you’re ready to start using it.

Administrator Privileges

Some commands, especially those affecting system settings like volume control, may require elevated privileges to execute successfully. To ensure NirCmd works without issues, follow these steps:

• Right-click on nircmd.exe.
• Select Run as administrator from the context menu.

Running NirCmd as an administrator ensures that it can access and modify system-level settings such as adjusting volume or muting the sound. If you encounter issues with specific commands not working as expected, this is likely due to missing permissions.

Verifying the Setup

Once NirCmd is set up in your chosen folder, open the Command Prompt to test if the tool is ready to use. Navigate to the folder containing nircmd.exe using the cd command and type:

nircmd.exe

If it executes correctly and shows the list of available commands, you’re all set to proceed with controlling your system volume using NirCmd.

Step 2: Launching NirCmd from Command Prompt

Opening the Command Prompt (CMD) in Windows

To begin using NirCmd, the first step is to launch the Command Prompt. Here’s how:

• Press the Windows key or click on the Start menu.
• Type “cmd” in the search bar.
• Click on Command Prompt when it appears in the search results. Alternatively, you can press Win + R, type cmd, and press Enter to open the Command Prompt directly.

Navigating to the Folder Where NirCmd.exe is Located

Once the Command Prompt is open, you need to navigate to the folder where the nircmd.exe file is saved:

Use the cd (change directory) command to move to the folder where nircmd.exe is stored. For example, if NirCmd is in the C:\Tools folder, you would type:

cd C:\Tools

Press Enter to execute the command, and you’ll be taken to that folder.

Invoking NirCmd Commands

To execute any NirCmd command, use the following syntax:

nircmd.exe <command> <parameters>

For example, if you want to set the system volume, the command would look like this:

nircmd.exe setsysvolume 5000

Here, nircmd.exe is the executable, setsysvolume is the command to set the volume, and 5000 is the volume level. Be sure to replace 5000 with the desired volume level in the valid range (0-65535).

Step 3: Setting the Volume with NirCmd

To adjust the system volume using NirCmd, you’ll use the command nircmd.exe setsysvolume . The parameter defines the volume intensity, with a range of values between 0 and 65535. A value of 0 represents mute, while 65535 corresponds to the maximum volume.

Example Command for Setting Volume

For instance, the following command sets the volume to a specific level:

ircmd.exe setsysvolume 5000

Understanding the Volume Level

In this case, 5000 represents approximately 7.5% of the maximum volume, offering a lower volume setting than the default. Adjust the value to suit your preference, from muted to full volume, based on your needs.

Step 4: Adjusting the System Volume Gradually with NirCmd

NirCmd allows you to set a specific system volume level and provides the flexibility to adjust it incrementally. This is especially useful when you want to increase or decrease the volume in small steps without setting an exact value.

To do this, you can use the changes volume command:

nircmd.exe changesysvolume <delta_value>

The represents the amount by which the volume will change. Positive values increase the volume, while negative values decrease it.

Examples:

nircmd.exe changesysvolume 5000   # Increase volume by 5000 units
nircmd.exe changesysvolume -5000  # Decrease volume by 5000 units

This approach gives you fine control over audio levels, ideal for scripting or shortcut-based volume management.

Step 5: Muting and Unmuting the System Volume Using NirCmd

Controlling audio muting through NirCmd is straightforward and especially useful for creating shortcuts or automating quiet periods, such as during meetings or nighttime hours. To mute the system volume, use the following command:

nircmd.exe mutesysvolume 1

This command instantly silences all system audio output. To unmute the volume and restore sound, use:

nircmd.exe mutesysvolume 0

You can also toggle between mute and unmute states using:

nircmd.exe mutesysvolume 2

These commands are ideal for scripts, scheduled tasks, or quick-access shortcuts, giving you seamless control over your system’s audio settings.
