In singleplayer, whenever I attack, the sound of the weapon firing or lightsaber swinging is delayed by a little under a second. This affects infantry, jedi, vehicles, starfighters, and turrets. All the other sound effects work properly.

I have not tried multiplayer.

I have fully reinstalled the game twice, to no avail.

I'm using Windows XP with Realtek High Definition Audio.

Anything I can try?
