After upgrading to Windows Vista from Windows XP the audio stopped working. I am having a nice set of headphones from creative. When I connect it to the pc there is no audio on it. I tried many settings here but nothing worked out. It was working really well on Windows XP. The volume icon on system tray is grayed out. I cannot click nor I can access anything on that. I need some help here to make it work. Can anyone guide me for the same. Thanks.
