Recently my sound schemes quit functioning,(no sounds and no sound when checking alternate sounds at bottom of window. Also the small button that lets you preview sounds is pale and neither highlights nor works). Also, websites that used to automatically start playing music when you go to them no longer do. CD's work fine. DVD's work fine. Also if I download music from the web to my computer and then play it that works fine also. Songs in my music library also work. My sound card is a creative media card. No hardware conflicts. All Devices enabled. Ran creative diagnostic. All good. Ran windows sound troubleshooter. No help. Volume controls are up and like I said the problem seems to be very specific. What does work sounds excellent. Any ideas would be most welcome. Thank you.
