I think you mean hovering over the menubar volume control. If so, then yes, it's impossible. Even if you click on it, you have to move the cursor over the slider portion of the control to use the scroll wheel (or, two-finger trackpad scrolling).

Hasn't it always been scrolling while your mouse was over the slider? This behaviour is consistent throughout the entire OS, from background windows to well...sliders.
