To do that, you first want to search out the method ID (PID) of the applying you wish to mute. You will discover the PID utilizing Job Supervisor (Ctrl+Shift+Esc) or utilizing the tasklist command within the command immediate.

After you have the PID, use the next command to mute the applying:

nircmd.exe muteappvolume [PID] one

Substitute [PID] with the precise course of ID of the applying. To unmute the applying, use the next command:

nircmd.exe muteappvolume [PID] zero

Muting Particular Audio Units (Superior): That is extra complicated and requires figuring out system IDs. It is much less generally used, however nircmd can management particular audio gadgets if their identifiers. Seek the advice of the nircmd documentation for particulars on the right way to obtain this.

Methodology Two: Utilizing PowerShell (Much less Dependable)

PowerShell affords some built-in capabilities for audio management, however they are often much less dependable and extra susceptible to points in comparison with nircmd.

PowerShell can generally use Part Object Mannequin (COM) objects to work together with the audio system.


# Warning: This technique could not at all times work reliably.
# Use nircmd for a extra steady resolution.

# Instance: (Doubtlessly unreliable)
# $WShell = New-Object -ComObject WScript.Shell
# $WShell.SendKeys([char]onehundredseventytwo) # Mute key

This instance makes an attempt to ship the mute key to the system. Nevertheless, the reliability of this technique varies relying on the system configuration and will require administrative privileges.
