Still, there's plenty people around complaining about a static background noise (distorting/clipping sounds) in inumerous racing-games, P&G v2.0 has been affected too (I've received inumerous PM's reporting this problem, with positive feedback after these suggestions).
...the culprits here are, most likely, the settings on the Creative XFI drivers, not the sound samples!
I have a Creative X-Fi XtremeGamer myself (vanilla, not Fatality) and it's pretty damn good once the driver settings are "tweaked", so I presume this will work for you with same or different Creative X-Fi soundcards as well.
I lost countless hours to find the best settings for it, as I was initially cursing the damn soundcard and blaming myself for its purchase for too much "coloring" in the sound (I already had a Focusrite Saffire-LE professional soundcard, completely different ballgame) and then... *BLING* ...found it's because too much crapp is ON (and wrongly so!) by default in Creative drivers, messing with the sound reproduction.
Ok, so starting on the Creative X-FI driver settings, I presume yours will use similar drivers (be it for Win 7, Vista or XP) compared to those that I have for my soundcard, so here's something that might help you there, and note, using X-FI panel control in "Game Mode"...

GENERAL SETTINGS (ones that I use no matter the speakers/headphones settings used):
(NOTE: I like to use Crystalizer "OFF", as it enhances the high-frequencies too much for me (this setting, when on, makes the sounds "brighter", with plenty more treble). If for any reason you decide to use it "ON", I would definitely not recommend going over 50%).
(NOTE: I use "flat" equalization -same as not used/unchecked- because that's how I prefer it for being "true" to the sound to be reproducted. Try that one first, before changing anything there).
(NOTE: two settings found here, SVM and EAX, are, perhaps, the biggest culprits of crappy sounds... SVM and EAX should be "OFF" (unticked), SVM and EAX forces effects, colloring sound, when and where it shouldn't be used).
BassBoost (set for headphones):
(NOTE: this option is very usefull to adjust amount of "bass" if using headphones (therefore if placed "ON", adjust to suit tastes) but, if you're using a speakers+subwoofer system, definitely better to leave this always "OFF". In this last case, and instead of using this setting, adjust the bass-level within your speakers+sub system (usually there's a knob for that in the back of the subwoofer)
5.1 (true) Surround Speakers
(NOTE: same settings used in any speakers system, 2.1, 5.1, 7.1, etc)
Finally, two things that are VERY important...
First, no matter what speakers/headphones settings used, never, ever, go over 80% in the "Master Volume" (3/4 turn in the chrome knob adjuster, as you see in screenshots) as this seems to be the max limit of sound quality volume in Creative cards (at least on mine it definitly is), from there on the signal gets distorted/clipping, and crappy sound reproduction is almost garanteed.
Second, you should have your subwoofer connected directly to its respective plug-hole on the soundcard (check the soundcard manual, if not sure) and the bass intensity at about 50% (there's usually a button/knob in the back of subwoofer), so if we imagine that knob as a clock, it should be set at 12'o clock. Adjust only to suit taste from there on (quality of subwoofer/speakers is obviously important too)...
Last suggestion, just in case you use headphones AND speakers, and if you really have to connect more than one jack (one for left/right speakers, another for headphones) to the same plug-hole (the left/right one, green one usually) in the soundcard, then use a (stereo) jack-splitter instead.
Alright... try P&G or other racing-games again and tell us later if it's any better!
