Forgive me but I am baffled by my sound problem.

I picked up Logitec X-540 speakers and realized that my old mobo didnt support Surround Sound. So I picked up a Creative SoundBlaster Audigy SE.

I am running Vista 32bit and have 5.1 set in Windows and the Creative Configuration. Now I get Surround Sound when playing a DVD, but when I go to play Battlefield 2 I can not get 5.1 for the life of me, does it have something to do with the card not beeing X-Fi?

I have searched the net and the forums and I am still lost.

I assume you have gone through the BF2 audio settings, enabled EAX and chosen 5.1 as the speaker config?

I enabled EAX but I could not find where to chose a speaken config within the game. I also switched between Software and hardware sound.

I'm not too sure about how to set it up for an Audigy SE. I do have the X-Fi and have it set to hardware, with Ultra/X-Fi setting (in BF2 audio settings) enabled and I get surround. I'll try and poke around tonight after I get home and see what I can figure out for you.

I'm pretty sure that once you're inside the sound settings in a BF game, you need to find where it lists your output or sound device. I believe it defaults to software or some generic thing. Be sure to change it to hardware, or if it's listed, your Audigy card. (For reference, BF2 & BF2142 actually lists the name of my sound card as an option -- I've got a Creative X-fi Xtreme Gamer if it matters)

Thanks for everyone's input. I will be playing with this tonight and hopefully get it working, or ill be puilling my hair out.

how are you connecting your sound card to your speakers?
'Surround' is an ambiguous term.
If you are expecting true 5.1 then you will need either a digital connection or 6 separate analog cables (derived from 3 sockets at the card).
However.
You can derive 'surround' from 2 channels using Dolby Pro-Logic, or DTS NEO.
It depends what you are trying to do.

battlefield games have surround.
i remember playing desert combatmod and getting freaked out by the sound of rounds imapcting the concrete behind me. this was with a series 1 audigy and a creative 5.1 speaker system using the six channel direct (green black and orange that connect to speakers from soundcard).
it is 5.1 in that it is discrete front and rear stereo and a matrixed center/surround.
i think that it adaps itself to the way the output device is set.
so if you have your creative settings set to headphones, the card optimises the sound info for headphones, the same from 2.1 to 5.1.
so you need to change the setting in the creative control panel.
or even in the advanced speaker settings in: control panel/sounds and audio devices/ speaker settings/ advanced.
the game will adjust, you can even alt-tab out and change the settings mid game.
