    AutoHotkey can do this, which you could compile and call from the command line

NirCmd is an application that does that and more.



Example of use:




  • Increase the system volume by 2000 units (out of 65535)
    nircmd.exe changesysvolume 2000

  • Decrease the system volume by 5000 units (out of 65535)
    nircmd.exe changesysvolume -5000

  • Set the volume to the highest value
    nircmd.exe setsysvolume 65535

  • Mute
    nircmd.exe mutesysvolume 1

  • Unmute
    nircmd.exe mutesysvolume 0

  • NirCmd is also great for getting a laptop to mute on every logon - this way it won't accidentally keep making the "ding" sound on the train (which I don't notice because of the headphones until an embarrassing moment when someone gets annoyed enough to point it out.....)

  • There's user-friendly interactive script I made for simplification that depends on nircmd.

Make the JavaScript files:



echo var oShell = new ActiveXObject("WScript.Shell"); >> volup.js<BR>
echo oShell.SendKeys(String.fromCharCode(0xAF)); >> volup.js

echo var oShell = new ActiveXObject("WScript.Shell"); >> voldown.js<BR>
echo oShell.SendKeys(String.fromCharCode(0xAE)); >> voldown.js

echo var oShell = new ActiveXObject("WScript.Shell"); >> togglemute.js<BR>
echo oShell.SendKeys(String.fromCharCode(0xAD)); >> togglemute.js


Show the volume control, so you can see what you're doing:



sndvol
(or maybe sndvol32)


Change the volume:



cscript voldown.js


Note: I've had this approach work reliably on machines that I've attempted to use it on. Helen's answer to Sibo Lin's StackOverflow question about this indicates muting isn't reliable, but volume-changing may not be quite as reliable. I suspect that the level of reliability may be different on different machines. This approach is using the technology of mimicking a keystroke, and specifically a volume control key on an enhanced media keyboard. At the time that Windows started supporting this, such a keyboard was basically a little-used frivolous feature that offered functionality that was previously available only with custom drivers. It wouldn't surprise me if this code was less polished, and less likely to work on some of the various (perhaps older) hardware that's out there. All that said, I haven't had troubles with it myself.

I don't recall if I actually tested this with that operating system. Still, if this approach doesn't work well, I don't expect it to cause problematic side effects.

  • Thanks for sharing those keycodes! Since my computer already has python installed, I was able to use this on the command line: pip install SendKeys (pure Python package for emulating keystrokes), followed by python -c "from SendKeys import playkeys; playkeys([(0xAE, True), (0xAE, False)])", which emulates a single press and release of the volume key. To emulate 100 distinct presses (for example), you can insert * 100 after the closing ] and before the final ).

Having read these posts and having looked for alternatives I decided to write my own command line utility, called SetVol, to set the volume. It works a little more simply than what is described in some of the other posts on this page, here are some examples that you would enter at the command prompt:



setvol 75
setvol -10
setvol +12
setvol mute
setvol unmute


There are other options too. I've released it as freeware, and you are welcome to visit www.rlatour.com/setvol for more information and to download a copy.



Enjoy

  • Thanks!! However, I REALLY need this for setting the mic volume. (I'm using Java but I don't expect JavaSound to do this.) Can it be added?

    Nov 30 '18 at 16:46











  • Awesome, thank you! Feature Request for future: ability to return current volume level as an errorlevel (so I can save current setting to later restore it)

    – ashleedawg
    Dec 13 '18 at 17:48











  • Sure, I can do that - and in fact, just did! The program has been updated to version 1.2 on the website, you may need to refresh your browser to see the changes. There is now a new parm 'report' that should give you what you want. Help on the website and in the app explains it use. Merry Christmas!

Owing and further simplifying Nircmd



@echo off
rem 65536 is 100%
rem device where zero is the default device
rem left and right
rem supports whole numbers only therefore throws "missing operator" error when specifying 655.36
set /a volume=%1 * 655
nircmd setvolume 0 %volume% %volume%


save it as a .bat file and execute by passing a parameter



eg: sound 60 will set the the sound volume 60%



make sure you put the bat file either next to the nircmd or in %windir% (or define its folder in %path%)

    Make the JavaScript files:



    echo var oShell = new ActiveXObject("WScript.Shell"); >> volup.js<BR>
    echo oShell.SendKeys(String.fromCharCode(0xAF)); >> volup.js

    echo var oShell = new ActiveXObject("WScript.Shell"); >> voldown.js<BR>
    echo oShell.SendKeys(String.fromCharCode(0xAE)); >> voldown.js

    echo var oShell = new ActiveXObject("WScript.Shell"); >> togglemute.js<BR>
    echo oShell.SendKeys(String.fromCharCode(0xAD)); >> togglemute.js


    Show the volume control, so you can see what you're doing:



    sndvol
    (or maybe sndvol32)


    Change the volume:



    cscript voldown.js


    Note: I've had this approach work reliably on machines that I've attempted to use it on. Helen's answer to Sibo Lin's StackOverflow question about this indicates muting isn't reliable, but volume-changing may not be quite as reliable.

I don't recall if I actually tested this with that operating system. Still, if this approach doesn't work well, I don't expect it to cause problematic side effects.

    Make the JavaScript files:



    echo var oShell = new ActiveXObject("WScript.Shell"); >> volup.js<BR>
    echo oShell.SendKeys(String.fromCharCode(0xAF)); >> volup.js

    echo var oShell = new ActiveXObject("WScript.Shell"); >> voldown.js<BR>
    echo oShell.SendKeys(String.fromCharCode(0xAE)); >> voldown.js

    echo var oShell = new ActiveXObject("WScript.Shell"); >> togglemute.js<BR>
    echo oShell.SendKeys(String.fromCharCode(0xAD)); >> togglemute.js


    Show the volume control, so you can see what you're doing:



    sndvol
    (or maybe sndvol32)


    Change the volume:



    cscript voldown.js


    Note: I've had this approach work reliably on machines that I've attempted to use it on. Helen's answer to Sibo Lin's StackOverflow question about this indicates muting isn't reliable, but volume-changing may not be quite as reliable. I suspect that the level of reliability may be different on different machines. This approach is using the technology of mimicking a keystroke, and specifically a volume control key on an enhanced media keyboard. At the time that Windows started supporting this, such a keyboard was basically a little-used frivolous feature that offered functionality that was previously available only with custom drivers. It wouldn't surprise me if this code was less polished, and less likely to work on some of the various (perhaps older) hardware that's out there. All that said, I haven't had troubles with it myself.



    Credits:




    • This answer was heavily influenced by Ryan's answer to Sibo Lin's question about changing the volume on the command line. (Having a good idea of how to do this, I looked for some example on how to get this done.)

    • I suspect that Ed Wilson's “Hey Scripting Guy!” blog on Microsoft: article about using a cheesy script to set speaker volume may have been the (direct or indirect) inspiration for many people who have suggested this approach.

    • Thanks for sharing those keycodes! Since my computer already has python installed, I was able to use this on the command line: pip install SendKeys (pure Python package for emulating keystrokes), followed by python -c "from SendKeys import playkeys; playkeys([(0xAE, True), (0xAE, False)])", which emulates a single press and release of the volume key. To emulate 100 distinct presses (for example), you can insert * 100 after the closing ] and before the final ).

    Having read these posts and having looked for alternatives I decided to write my own command line utility, called SetVol, to set the volume. It works a little more simply than what is described in some of the other posts on this page, here are some examples that you would enter at the command prompt:



    setvol 75
    setvol -10
    setvol +12
    setvol mute
    setvol unmute


    There are other options too. I've released it as freeware, and you are welcome to visit www.rlatour.com/setvol for more information and to download a copy.



    Enjoy

There is now a new parm 'report' that should give you what you want. Help on the website and in the app explains it use. Merry Christmas!
