Speaker Configurations Change Randomly In Windows 7?

I currently use an old Creative X-Fi Xtreme Music sound card in my system. Worked wonders under XP (What didn't, honestly) and upgraded recently to Windows 7. My sound in Windows 7 works great, all speakers emit their proper sound in their proper positions and when I play games, I can hear everything like I did in XP. Someone sneaking up from behind has no clue that I can actually hear them. -.- Anyways, to my point...

Front Left becomes Rear Right,
Center Becomes Front Left,
Front Right Becomes Center,
Rear Right Becomes Front Right
My Rear Left Makes No Sound
And Sub Becomes non-existant!

This all happens just after a quick *Pop*, and suddenly someone speaking dialogue in front of me sounds like he is behind me! The only way I have found to fix it is to open my Creative console (I use Game Mode (Entertainment proves just as problematic)), set my speaker configuration to 2.1, then set it back to 5.1 and the sound works properly again! But, wait about another half hour, *Pop*, back to messed up configuration.I have an XP partition, works fine under it with no sound re-arrangement,Figured It was my speakers, Bought a new set, does the same thing.I've checked the cables: Everything is as they should be and placed correctly Does this in OLD and NEW games, as well as iTunes and WMP.
