Using Lion, latest and fully updated.  At some point in the past week or so the volume control stopped having an effect.  Using either the keyboard function keys or the item in the task bar, the graphics look good and the blocks/slider move around just fine, but there is no effect whatsoever on sound output.  I can control the volume in whatever app I'm using, whether it's a Web app or local app with its own volume control.  But the system volume controls no longer have an effect.  This is true whether or not I'm using the display output or headphones.
