I'm looking for a way to adjust the volume of my speakers via a keyboard a custom shortcut.

If this is not possible, is it possible to do in C++? Thank you in advance.

You can do it with the program AutoHotkey, available here:

If you wanted to program it in C++, it is a pain in the butt to change mixer controls, but it is possible as explained in this Stack Overflow article:

I personally almost find it a must have, as its a pain in the ass since i listen to music and play games, to have to minimize the game to adjust volume.

also, a "next/previous track" button is nice to have


The result of origin.. Oh and ponies

Isn't it easier just to adjust speaker volume?

@ionstream Thanks I'm checking that out now.

I'm using a desktop and the keyboard that it came with has no volume controls, and I don't feel like buying another keyboard if I can avoid it.

Method 1: Not so elegant
~ via explorer open the system32 folder. (usually C:\Windows\System32)
~ send a shortcut of sndvol.exe to the desktop (by right-clicking)
~ right-click the shortcut on the desktop and click properties... then select the shortcut tab.
~ click in the shortcut field (it will say none).
press the key combination you wish to launch the shortcut ie. Ctrl+Shift+Alt+V.
~ That will launch the volume mixer, use up and down arrows to adjust volume
~ use alt+f4 with the mixer still active to close it

You can alternately use the above method to launch a batch or vbscript. you can assign any key combination to launch a volup vbscript,, and a voldown vbscript. I'll post an example script below...

Method 2: More elegant than Method 1
A VBscript solution. I think this will give you enough to to play with and figure it out. Just save the snippet in notepad as voltest.vbs to your Documents [folder]... send a shortcut of the script to the desktop. Launch it. I'm sure you can work it into two separate scripts,, and map the key combination via the shortcuts using the same method as above. Happy Coding!!!



For loop example. Should look familiar......
