Hey there everyone, I'm pretty sure that this issue has been addressed previously and happens to quite a lot of people out there. So the problem is my computer does have sound and everything, but when it comes to playing computer games there are no dialogues and background music. Some sounds in games you can hear but never when people speak. I've checked settings for each game on my computer but still nothing works. I heard from other forums that you should update your soundcard or something. Anyway, my computer runs a Windows XP with a Realtek HD sound card.

Any help would be much appreciated.
