Hey guys, Today I reïnstalled Windows Vista. I remembered that when I installed SP1, the crackling sound of my X-fi appeared. And now I am still having this problem.. I have all updates installed for Windows Vista Business 64-bit (including service pack 2). And installed the latest X-fi drivers from the Creative website. So what to do about the crackling sound? I really do not see why Creative still did not notice it.. Vinnie.
