I am currently unable to adjust the volume of my speakers using Control Panel. Each time I set the volume lower, the indicator rises back to the top (maximum volume). At the same time, I have also had a volume "gadget' appear on my screen indicating that the volume is at the maximum. I am also unable to make this gadget go away. I suspect it will disappear when I am able to lower my volume once again. In the meantime, any suggestions on how I can regain control of the volume would be greatly appreciated.
