How to control master volume in Windows 7?

Question

Some keyboards have volume controls on them that can be pressed anytime to control the master volume. My keyboard does not have that. Is there a way that I can create a key macro that will work like the volume controls on those keyboards? It should always allow me to control the volume, even if I'm playing a game.

Answer 1

I just did this with my laptop. I used AutoHotKey

Here is the script

#PgUp::Send {Volume_Up 3}
#PgDn::Send {Volume_Down 3}

so doing Win+PgUp or Win+PgDown changes the master volume.

1. If you don't have it installed already, http://www.autohotkey.com/
2. Once installed, right click your Desktop, and choose new AutoHotKey file
3. Make sure to title the file ending with .ahk (for example, I used "controls.ahk")
4. Paste the code in from above
5. Save it, and double click the script in windows explorer

To run it at startup

1. Use the AHK provided "Convert to exe" utility (or you can right click the file and select "compile script")
2. Create the .exe in "C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"

Volumouse

provides you a quick and easy way to control the sound volume on your system - simply by rolling the wheel of your wheel mouse.

Answer 3

NirCmd is an application that changes the volume 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

You could use it, together with AutoHotkey to invent your own volume keys.

Just found 3RVX. The web site is 'down for maintenance' but you can still download the software. And a documentation page is still available.

Simulates the look and feel of the OS X volume overlay (different skins are available) and you can configure key combinations.

You could use this AutoHotkey macro: Volume On-Screen-Display (OSD) -- by Rajat

The interesting part is here:

vol_WaveUp:
SoundSet, +%vol_Step%, Wave
Gosub, vol_ShowBars
return

vol_WaveDown:
SoundSet, -%vol_Step%, Wave
Gosub, vol_ShowBars
return

vol_MasterUp:
SoundSet, +%vol_Step%
Gosub, vol_ShowBars
return

vol_MasterDown:
SoundSet, -%vol_Step%
Gosub, vol_ShowBars
return

If you modify the script and remove the "Gosub", you can change the volume without the OSD bars.

Answer 6

Try Sound Volume Hotkeys

This tool allows to control sound volume using system-wide hotkeys. Customizable on-screen sound volume indicator will show you the current level.

Answer 7

Although it's a very old question, I want to report my findings on this topic. I stumbled across an AutoHotKey_L library whilst trying to overwrite my keyboard's Volume_Up and Volume_Down global hotkeys. The purpose was to be able to control master volume while running restrictive, key press consuming fullscreen applications/games (Bethesda's games as an infamous example). The functions are pretty straightforward, so I'll just post a little example:

Volume_Up::
    newVol := VA_GetMasterVolume() + 5
    VA_SetMasterVolume(newVol)
return

Volume_Down::
    newVol := VA_GetMasterVolume() - 5
    VA_SetMasterVolume(newVol)
return

In principle, this code contains everything you'll need. It overwrites both keys to do the same as before, but instead of relying on the OS to catch the keypress, AHK sets the volume by itself. Of course, you can specify any other hotkey. Since there doesn't seem to be a built-in function to change the volume relatively, you'll have to get the current volume first and then in-/ decrease it at will (here: 5). VA_SetMasterVolume accepts values between 0.0 and 100.0, inclusive.

To get this working in restrictive fullscreen windows, it was sufficient to call the #UseHook directive at the top of my script.
