I just recently installed Windows 7, after all was up and running I started installing other programs. Installed my Itunes and proceeded to listen to music. The hotkey mute button would show the mute icon on the scree, but didnt affect the sound, same with the volume icon on the screen. It would show up , but no movement or change in sound. I then tried the other hotkeys and the brightness one worked fine. I am usuing a Sony Vaio VGN-FS840/W. I have tried installing all the updated drivers. After reading several forums, I downloaded the shared library, utilities update and the other files that were suggested, but the same outcome. Any help with this is appreciated. JD
