If you have a dual core maybe you have to deselect one of the core's or choose the other core when you are running the game. Start the game, alt+tab out, press CTRL+ALT+DEL and bring up the task manager. You will have to "change affinity" for nbalive07.exe by disabling one of the core's, I think you need to disable the second core.
You may also need to update your sound drivers because I read that it may not be a problem with dual core support from the game, but from the sound drivers.
I'm only repeating what I've read, you should look here -
