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

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 2

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
2. Create the .exe in "C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"

Answer 3

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 4

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.
