ATI HD 3xxx + Realtek HD problems on Windows XP.

I have a computer with an ATI HD 3850 graphic card which has, practically, included a sound card. The problem is that on the motherboard I have a Realtek HD sound card, which enters in conflict with the graphic card. From what I have observed, ATI starts the conflict and forces Windows to keep the sound played via their drivers (which is done through a HDMI connected to graphic card). This will make any try to play sound through motherboard's sound card to fail.

The solution is to go on device manager, and there to disable ATI HD sound card (under sound devices). Windows won't have any option, and will automatically playback sound via Realtek HD sound card.

This should apply to any ATI graphic card from series HD 3xxx.
