So i just did a clean install of windows 7 64bit onto my new motherboard, its a asus M5A99FX PRO R2.0 and ive installed all of windows updates, and drivers, ive installed all the drivers that came with my mobos disc, and the realtek hd audio driver isnt showing up as an audio device, its neither in my device manager or control panel, ive tried uninstalling and reinstalling many times and tried updating the driver and it still isnt working, i made sure the on board audio is enabled through my bios to, but nothing ive tried has worked, i went into dev manager and viewed through "connections" and i think its showing up as HD audio controller but thats it, i tried updating, uninstalling it but its not working, even updating my bios to the latest version, im running sli gtx 460's if that helps, please get back to me its very frustrating, both the front and rear jacks arent working :/
