Hello I just had to replace my Asus M5A97 board because of a faulty bios chip. I bought this new Asus M5A99FX Pro motherboard, but my sound isn't working. Foolishly I forgot to uninstall all of my drivers before swapping boards. I installed the driver and I could here the first ping when you install the drivers, but then no other sound. I've tried Uninstalling both and reinstalling, but still no change.
