still can't the surround after reading all of the answer, some of them says that you need a creative sound card or xonar, which i have (xonar dx).
i already modified bioengine.ini the way its suppossed to look, courtesy of one of the thread here. but still no luck. what should i do?
I believe the requirement is that your sound card supports EAX, but even that's not a given. I have an old PC with a Creative sound card that doesn't work, while my other PC with a different Creative card does get surround in the game.
The sad truth is that Demiurge didn't bother porting the audio engine correctly. While they added environmental audio for EAX users, pretty much everyone else gets the short end of the stick.
It worked on my Creative Sound Blaster X-fi Xtreme Audio. I'm not sure what the other incompatible card was, but I think it's an older Creative Audigy.
Now that I think of it, there's a software solution by Creative that allows software emulated EAX on onboard audio. I once tried a free demo and it worked on integrated Realtek. Played ME1 with surround and environmental audio. http://www.creative.com/oem/products/software/x-fimb.asp
X-fi MB works on Asus and ASrock boards. Trial location: http://asrock.com/feature/SoftwareSuite/index.asp
I recently got a new PC and this thread reminded me I wanted surround sound in Mass Effect. I have an ASRock board with Realtek HD, and bought X-Fi MB3 from Amazon (the store page vanished after I checked out so I can't link it).
It's working beautifully. Dialog comes through the central speaker, all five channels are being used, and the audio is overall a bit crisper than before.
I hope your experiences are similar.
