Need to be spoonfed a basic batch script to change system audio

paradoxum · Dec 4, 2023

Not sure where to post help for things like this, it's kind of a customization thing but I didn't think it'd fit there..

Anyway I have an alternative boot sound I use, but the boot sound uses windows system audio in the mixer, which I normally have at '1', because the slider for it has been uneven for years and anything higher is way too loud (not just me right?).

Anyway I'd like a script that I can add to task scheduler or something that will set the windows system volume to 50%, and then after 10 seconds set it to 1%, then I will have scheduler run it every hour after the first run, and if possible I'd like it to keep setting the system volume to 1% across all output devices then, because, I'm not sure what it is it could be anything from plugging my headset dongle into a different USB port, but my system volume is constantly being reset to 100% and I'm greeted with the loud DADUNNGGGG noise when there's a windows error popup.

I tried to get started myself and I won't even go into the actual script cause things I pulled from stackexchange and tried editing nothing worked, but I found this tool SoundVolumeView and it has extensive command line args;

View / change sound volume on Windows 11/10/7/8/2008 from command-line or GUI

Display, change, mute, unmute the volume level of sound components on Windows 11/10/7/8/2008 from command-line or GUI

I've been just trying things like
>
:: Mute/Unmute
svcl.exe /SetVolume "System Sounds" 75
Etc.

And a little mockup of what I'm looking for;
:: Mute/Unmute
svcl.exe /GetMute "Headphones"
if muted
svcl.exe /Unmute "Headphones"
svcl.exe /SetVolume "System Sounds" 50
wait 5s
svcl.exe /SetVolume "System Sounds" 1
every 60min repeat line 7

Forgot to say thanks if anyone can help. I really struggle with cmd line stuff and things like regex etc. (I know this has no regex but it often comes with making batch files.)

Code:

:begin
set isMuted=svcl.exe /GetMute "Headphones"
if %isMuted% equ 1 goto muted
:muted
svcl.exe /Unmute "Headphones"
svcl.exe /SetVolume "System Sounds" 50
timeout /t 5 /nobreak
svcl.exe /SetVolume "System Sounds" 1
timeout /t 3600 /nobreak
goto begin

I haven't written a batch file in years but the above should work? Otherwise it might be better to write it using PowerShell instead.

Haven't done this personally but maybe this will help? I think @x BlueRobot probably has it correct.

Auto set volume in a batch file

this is as close i could get to making a batch file to automatcially set the volume down i need to rewrite script so that just set it to 25% but cant figure out how to do and if already below 25% just leave it please someone could edit my code to achieve this? it only reduces by 40% the =20...

I haven't tested this myself yet but this should work?

Code:

# Executable File Path
$exe = "svcl.exe"

# Sound Sources
$headPhones = "Headphones"
$speakers = "System Sounds"

# Checks if the sound source is muted
function IsMuted {
    [Parameter(Mandatory=$true)]
    param([string]$soundSource)
    Start-Process -FilePath $exe -ArgumentList "/GetMute $soundSource"
}

# Unmutes the specified sound source
function Unmute {
    [Parameter(Mandatory=$true)]
    param([string]$soundSource)
    Start-Process -FilePath $exe -ArgumentList "/Unmute $soundSource"
}

# Sets the volume of the specified sound source to the desired level
function Set-Volume {
    [Parameter(Mandatory=$true)]
    param([string]$soundSource, [int]$level)
    Start-Process -FilePath $exe -ArgumentList "/SetVolume $soundSource $level"
}

# Sets the script to "sleep" for the desired timeout period
function SleepScript {
    [Parameter(Mandatory=$true)]
    param([int]$period)
    Start-Sleep -Seconds $period
}

while (true) {
    $isMuted = IsMuted -soundSource $headPhones
    if ($isMuted) {
        Unmute -soundSource $headPhones
        Set-Volume -soundSource $speakers -level 50
        SleepScript -period 5
        Set-Volume -soundSource $speakers -level 1
        SleepScript -period 3600
    }
}

audioctl.exe is a Windows audio control utility (pycaw/comtypes-based) with a scriptable CLI and an optional GUI.

It lets you automate common audio tasks like listing devices, setting default playback/recording endpoints, changing volume, mute/unmute, toggling “Listen to this device”, and managing Enhancements.

A key feature is learning vendor/driver toggles: audioctl can watch what Windows or your driver changes in the registry when you flip an enhancement or FX setting, save that behavior, and then reproduce it later, even if there’s no official API. Once learned, you can toggle individual effects (e.g. Bass Boost, Loudness) on demand.

It also has fast, read-only commands to safely query current audio state for scripts, hotkeys, or status displays.

The GUI is optional and just a helper layer, useful right-click menu for actions and guided learning, while the CLI remains the source of truth and is built for repeatability and automation.
