Sound is realtek

I tried the drivers at hp site support by bring up my model and they dont work, no sound. Heck not even X-plane 9 will start. Thankfully FSX will. I hope someone can help me please.

What operating system do you have? Try uninstalling the sound card driver then reinstalling it.

My ops is XP Pro Sp3 and the above dont work.

Since your sound is Realtek I presume it is onboard sound and not a sound card. Open your BIOS and make sure you have selected onboard sound. You may also have to open the Realtek control panel and select your desired sound output configuration.
