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
    }
}
