Is there a way in Java (+- JNA) to set the master system volume reliably in XP+Vista+Windows 7?

Question

Appears that java's sound API's work well for single streams, and even for setting the input from the microphone, but not for setting the master volume level in Vista/Windows 7.

http://stackoverflow.com/questions/294292/changing-master-volume-level/294525#294525 only works on XP for the master volume

Anybody have something that'll work for all of them (without compatibility mode or controlling the mouse to increase volume level [robot-like]).

Answer 1

seeing as there's no other answers, my current one is to use jna to send the keyboard strokes for volume up and down: http://superuser.com/questions/82229/how-to-control-master-volume-in-windows-7/86227#86227

Ideally, however, you'd hook into a dll that was "vista aware" and could actually control it right. And somehow do it the "right" way for XP, as well, using the legacy way.
