If you are in 'Gaming Mode' with the X-FI, try switching to entertainment mode and see if that helps.
Another siimple thing that can fix a 'lot' of X-FI issues is simply hitting the 'reset to defaults' button on the console.
Hope that is some use to you.
I end up reinstalled the windows XP, and the problem seems gone.
