Hmm... Creative's driver support absolutely sucks, I'll have you know... I have the dickens of a time trying to just get my card to work at all.. once its done, it works fine, but it takes me a few hours to get it running.. it keeps saying "no Creative hardware found", even though I bought the darned thing straight from Staples, and it's sitting in my computer. Updating is impossible, IIRC. So, just because it says you have the latest drivers, I wouldn't trust it... under (in start menu > programs > creative) Creative System Information, under Creative Products tab, Creative Product ID > Sound Blaster Live! 5.1, what is your Driver version? Mine is 1.4.0
