Changing the size of the audio volume increment of the “volume up” / “volume down” keys

Question

Same as this question but for Windows: How can I adjust by how much the sound volume changes every time I press the volume change keys?

I'm on a Windows 7 laptop. It has "volume up" and "volume down" keys on the keyboard. Pressing them changes the volume by a tiny amount. Is there a setting or registry key or something to change that amount, or will I have to install third-party software to do it?

Answer 1

Yes a third-party app seems to be the best solution.

Microsoft's response to the problem is this;

The keypresses are sent to the OS as APPCOMMAND_VOLUME_UP and APPCOMMAND_VOLUME_DOWN HID messages. These are then translated to calls to IAudioEndpointVolume::VolumeStepUp() or IAudioEndpointVolume::VolumeStepDown(); this is hardcoded to 51 steps.

Possible mitigations are to toy with the keyboard refresh rate in the Control Panel or to write an app that listens for the APPCOMMAND_VOLUME_UP HID messages and does its own thing.

Some laptop manufacturers provide a third-party application that captures special keypresses and provides OSD etc, and this might be customizable.

Otherwise I'd also recommend 3RVX as per your comments.
