windows audio device graph isolation stopped working

[wicken]

Some of you know that i had to format my computer because of the directx problems, everything is back to normal but now when i am playing nfs world i keep getting constant freezes (3-5seconds) the game doesn't stop working but the audio stops working. Anyone can help me with this please?

As this apparently is only a problem in the game, you may want to repost on the graming section for help.
