Ok, so I have that problem with the Creative cards where it doesn't play nice with my Nvidia chipset and Win 7 64. Horrible sound when it works at all, clicks and pops and crackles. But most of the time it doesn't work at all.
The sound card in question is the X-fi Platinum I believe, and my mobo is an Asus A8N Deluxe.
I have been totally unable to find any information on decent sound cards that WILL work given my equipment. I would like to find something that provides rich sound similar to the X-fi Platinum. It was great while it lasted. Now I can't even get the crappy onboard sound to work!
Help! I hate having no sound
