Are there known problems with SB Live 5.1 X-Gamer and Windows XP?

[bullion416]

I have tried many things to try and get my surround speakers to work. I have a 4.1 setup and only the front speakers work. I have the updated sb live drivers. The only way I can get the surround to turn on is to either go to the control panel sound settings and re-select the 4 speaker setup (which it is already set on) or if I go into Creative's Audio Headquarters and re-select 4 speaker setup (which it is already set to). I noticed that when I play a song in Winamp, the back speakers have a short crackle noise and then only the front speakers work. I NEED HELP....what could be the problem?
