Graphic card audio lag

[AzureFlameXIII]

Hi.
I have a Nvidia Geforce 8400Gt GPU and when i play so of the newer PC games like MassEffect 2, Splinter Cell Conviction, and Just Cause 2 the cut-scenes are out of sync with the audio (were the audio is playing ahead of the video).

I was just wondering if getting a new graphics card would fix. Im getting one anyways (XFX Ati HD 5830)

I also have a problem were with these games i have 2 change the audio to stereo or quadraphonic and cant keep it at 7.1 or else i cant hear in-game voices (sometimes cut-scenes), (In Just Cause 2 i can hear any speaking only sound effect and BGM).
I know this doesnt do anything with graphic cards but i would like the help.
I only have the Audio chip that came with my MoBo (GIGABYTE GA-EP45-UD3L).

Thanks for the help

Well, the 5830 has a built-in audio chip for it's hdmi output, so if you use that you'll be in good shape.

But still, you shouldn't need a new graphics card just to get the sound to work correctly. It seems that a problem like that would be fixable, I just don't know how.
