How do I prevent keyboard volume buttons from controlling Winamp volume as well?

[ksio.amaral89]

I have a multimedia USB keyboard plugged into a laptop with the standard "volume up" and "volume down" keys, besides the usual "play", "stop" and "skip to previous/next track".

The issue is: when I press volume down/up keys, not only they increase/decrease the soundcard volume level (Windows main volume level) but winamp volume control as well, and it's really obnoxious, because if I intend to lower or raise the volume in short increments, it results in a much lower/higher audio gain change as winamp volume is being changed too.

My intention is to set Winamp gain control slider all the way to the right (maximum loudness level) and then use the volume control keys to exclusively control the soundcard volume level. How can I accomplish that?

In Global Hotkeys plugins options, both "Enable default multimedia key support" and "Enable" (above a list of actions and corresponding shortcuts) boxes are ticked.

Thanks in advance.
