I have a HP Pavillion Elite d5200t and like an idiot I just installed an update from MicroSoft for Relteck today that has killed my sound. My windows media player has no sound but if you go to sound in control panel the realtek is OK and the bar is going up and down but I get no sound out of my speakers. Everything was working OK before this update. Has anyone run into this yet and if so what was the fix? Forgot to add and I'm using Vista Home Premium SP2 64 bit. Creative sound card is working OK. I rolled back the driver, but that didn't help.
