Help! My Volume mixer won't open so I can adjust the volume on my computer. Volume is stuck on loud. When I right click on the speaker in my tool bar, it gives me the option to open volume mixer. When I click on that option, nothing happens. I don't even get any kind of error messsage. I have a presario notebook cq50 laptop computer. Windows Vista System. Can you help me fix this problem.
Configuration: Windows Vista Internet Explorer 8.0
