Unfortunately there is no Windows XP driver for any of the new line of SB Recon sound cards, you are out of luck.
The reason is that the way audio is processed in Vista/W7/W8 is completely different from the way it is handled in Windows XP ( this was done to improve the quality of onboard audio...let the cpu do more audio-processing tasks than was previously possible with single core machines using older Win XP. So the way the audio chip talks to the rest of the system is handled differently than a "pure hw audio solution" that XP was designed around.
XP is no longer supported by Microsoft officially as of this month, and they will no longer be giving updates for it anymore.
The OS is over 10 years old now ( 2002 ), do you really expect Creative to support XP with their latest product? They support Vista/W7/W8 drivers of course for this new Recon ( much of the audio processing is done by algorithms on the cpu, and some on the "audio core processor" on the card itself, simplying the sound card hw requirements on a massive scale... very cheap to manufacture... but of course it has no XP driver as that would involve a LOT of work for an unsupported 10 year old OS... not gonna happen... and if somebody does write their own hacked XP driver for it then Creative will turn around and sue that person, just like they did before over modded drivers...( referring to the Audigy driver fiasco years ago ). BTW you won't damage your card by installing the "wrong" sound driver for it, it simply won't work is the end result...
In a perfect world it would be nice if all the manufacturers wrote drivers for every OS on the planet, new and old, but it aint gonna happen for financial and marketing reasons.
You cannot really fault Creative here, XP is officially discontinued you know... all their earlier products ( X-Fi and previous ) DO support Win XP with their drivers, this is 2013 and Creative is only supporting Vista and newer Windows OS with their new products going forward in time...which makes sense, even if you don't agree with them...
The other thing you could do is simply disable the sound driver completely in XP in Device Manager ( disable the "wrong" audio driver for your card, even if you install no driver for it manually, XP will automatically try to load a generic audio driver for it which of course won't work as you know , so just disable that device completely in Device Manager. ), then plug in a set of cheap USB headphones ( $10 to$20 for decent Logitech set, I have a pair that sound pretty good actually considering I paid $10 for them... ).. .they use their own USB sound chip ( well the driver actually uses cpu to process audio but I mean it does not use any onboard or discrete sound card in your computer to work, they work independently and on their own through USB cable and ignore any onboard or discrete audio card in a system ). That would work for sure.. not ideal, but at least you would have sound that way in XP...
Here is the pair I have ( I normally use Sennheiser HD-555 but my Logitechs are used for backup and for clients systems etc. when I want a cheap set for testing etc. ) I see they are down to just $8 now ( refurbished but like new ) , and out of stock of course, but just to give you an idea what to look for:
