Command line control of Speaker Properties and Balance

Question

The left speaker of my laptop is not working well so I need to decrease left speaker level to 0% every time I use it. But whenever I need to use headphone I have to reverse it to 100% for left headphone.

I am here to find a solution through CMD. where I can switch from 0% to 100% volume of my left speaker using a .bat file.

Is there any way to control

speaker >> speaker properties >> levels >> balance

using command prompt?

Note: I have win10 (64bit)

Perhaps you should to use vbscript instead of batch, take a look at this [How to control Windows system volume using JScript or VBScript?](https://stackoverflow.com/questions/2216334/how-to-control-windows-system-volume-using-jscript-or-vbscript) — Hackoo, Oct 21 '19 at 08:15
@Hackoo I ask for `cmd` because one can place a `batch file` on desktop. Every time he/she need to switch form 0% to 100% he/she will only have to run that batch file. — VBAbyMBA, Oct 21 '19 at 08:31
@IbneAshiq you can place a VBScript on the desktop too. Just save the code in a .VBS file and you will be able to execute it by double-clicking it. — Étienne Laneville, Oct 22 '19 at 15:26

If you want to do it in batch script, just save this code below as Switch_Mute_Volume.bat

So, When you double click on this batch script the volume switch from Volume (no mute) to mute. and when you repeat this action another time the volume switch from mute to no mute

@echo off
Title Switch Mute Speaker Volume
(echo CreateObject("WScript.Shell"^).SendKeys chr(173^))>"%Temp%\%~n0.vbs"
cscript //NoLogo "%Temp%\%~n0.vbs"

And if you want just to do it only in vbscript : Just save this code below Switch_Mute_Volume.vbs

CreateObject("WScript.Shell").SendKeys chr(173)

Here is another method using a HTML Application HTA If you want to use a GUI : Just copy and paste this code below as Switch_Mute_Volume.hta

<html>
<head>
<HTA:APPLICATION 
APPLICATIONNAME="Volume + - ON/OFF"

As mentioned in the question. Only left speaker volume need to be change. Your answer is about switch between mute volume. — VBAbyMBA, Oct 22 '19 at 15:38
@IbneAshiq So in this case if you found an answer to your issue, just let me know. Good Luck ! — Hackoo, Oct 22 '19 at 15:40
