I have a Gigabyte GA-EP45-UD3R with the Realtek HD Audio. I did not install a sound card as I believed that this was all I would need. Up until I installed the new F1 2010 my sound has be fine. Have other racing games as well as all of the Call of Duty and Brothers in Arms and no problems. With the F1 2010, the sound is more of a reverb. I have been told to get the latest drivers, but I have also be told that if the sound is part of the motherboard that I shoud not download the drivers from Realtek. Is the true, or would it be ok to go to Realtek.
