It happens on digital for some and not for others. I also had a weird issue where I heard a CONSTANT, very high pitched screeching noise in all modes but Audio Creation mode set to 44.1Khz playback. This happened through both Digital and Analog.

Also, the buzzing noise only occurs with certain GPUs as well.

- All features may not work properly in Windows 7 in the current driver.
They HAD a beta but that was months back and they have yet to publically release it.

- S/PDIF will not transport EAX, CMSS3D or other effects on any Creative card.
I find this hard to believe given the proof about mixing stereo over S/PDIF but I asked them about this and asked if it uses the internal DAC making the use of an external DAC pointless. They didn't really reply, just got stuck in another useless information circle.

This conversation was the most recent one. I e-mailed them after reading this thread oddly enough. The first time I e-mailed them they said it was possible, now I get these conflicting statements. To my knowledge, you can buy the DDL pack and apparently have EAX mixed with 5.1 and sent over S/PDIF but you need a Dolby receiver to decode it. The possibility of EAX with stereo S/PDIF is anyones guess. I plan to try it in less than a week with my X-Fi XtremeGamer Fatal1ty Pro. I did set the default sound device to S/PDIF out on Windows 7 and then loaded up BF2 with the audio set to X-Fi Ultra Quality and the little volume meter in the sound panel acted like no sound was being passed through which would support one of the posts in this thread. However, I get the same results when using WASAPI through S/PDIF output in Foobar so... again, it's anyones guess. I will post back my findings.
I've read a lot about this issue too, because buying an external receiver only for testing is not that easy.

Well, if you want stereo EAX over spidf, then it can be done by all xfi cards, at least is what I understood by Newegg posts, the problem is if you want 5.1 channels,
Some people say there's white noise, others say its ok for Creative xfi, but not for Prelude, because Prelude has not the option Digital out, it just bypass xfi processor(EAX) if IO out selected,

apparently Auzentech cards and also Creative with modded drivers, can do Dolby Digital Live, which decodes on the fly to external receiver, so you get EAX,
but this is not the pure EAX you get on analog out, plus it put loads on processor,

So as a conclusion, (but I can be totally wrong), if you have an external receiver, you better use the analog in on the receiver, at the cost of having more cables around the house, hope you dont have a high end receiver because yo're bypassing the good DAC..

btw: why do you want stereo EAX, its on surround that it comes to life..

Assuming you're asking ME, I prefer headphones. I HAD a somewhat nice 5.1 system but it was too loud and the engineers forgot to put a volume control on it and having to set games at 5-10% volume and windows mixer to 5-8% for the speakers and then way back up for headphones just got old. When I want detail, I like headphones I don't really use the positioning but I enjoy the reverb and delay effects that EAX provides.

OK
I tried my xfi connected spidf optical to my Moodlab DAC, which is only stereo, I use Windows7,
well configuring the game for stereo it works a charm, detail, position etc (Wolfenstein), so your problem is resolved,
unfortunately, I don't have a receiver or multichannel DAC, but I tried PES 2009 on the Moodlab, the pes got the comentary voice only on the center channel, so you would expect no comentary with the moodlab, but only Left and Right channels,
well there is the comentary voice, but dont know if this is due to spidf signal of xfi, or maybe that the DAC cannot decode Dolby surround,

Not to mention, depending on the receiver using analog connection may provide the best sound. Depends on the quality of the DAC used in the soundcard over the DAC in the receiver your using.

As for the other subject, S/Pdif is a stereo I/O method. So you can have EAX effect through S/Pdif on the Forte, HTHD 7.1. or Creative branded cards.
for digital surroud cards with encoders, such as Dolby Digital Live and DTS-C will take the EAX effected audio and encode to one of these standards your receiver can decode. That is really the purpose of the encoders to allows surrounf audio over digital output.
However, that being said both DTS-C and DDL are lossy encoding methods.
I would test both analog and digital and use my ears to decide which sounds the best.
