Taskbar Volume Icon Not Working - If you're wondering what the problem is, it could be related to UI interaction. Many icons on the taskbar behave in the same way. Mouse hovering is possible, but it doesn't appear to do anything when you click on the icon. The volume icon issue doesn't appear to have any effect on the audio output from the computer. The volume icon works well and can be used on either the keyboard or the computer to adjust the volume. However, the software does not work. This is a problem for people who connect their laptops to large displays. The device is often not in reach.
