Answer 1

As far as I know, HD Audio Render is a generic driver type for an HD audio card. You should be able to follow these instructions to find out the manufacturer and model of your audio card and then find the appropriate drivers. If you find the vendor & device string and need help finding the driver, you can always edit your original question or leave a comment on this answer. Cheers!
