I recently uninstalled programs and reduced the number of programs that open at start up. After I did this, I have no sound. I have no audio device. There is nothing in device mgr. Downloaded the soundmax integrated digital audio driver for Windows XP. I get the error message windows audio service has been enabled! please restart your computer and run the soundmax installer again. I attempted to restore computer to 10/28 when I had no problems and date not available. The computer is not muted.Do you have any ideas as to what I can do to restore sound?
