I just got a Hurcules Fortissimo 7.1 sound card as suggested by someone on this forum. Now when i play games that support EAX, i hear no rear sound. Ive played Halo, BF1942 DC Mod, and Americas Army. Evertime I throw a gernade and turn around to try to hear it blow up behind me its complete silence. Firefights in BF1942 cannot be heard behind me either. In Halo the plasma rifle sound cuts out(assuming its trying to channel rear sound). Of course my sound card settings are enabled for EAX and im using the optical input to my external receiver. My reciever is an AIWA 5.1 with an optical and coaxial spdif inputs. One rumor i heard is that EAX cannot pass through this digital output on the card. My reciever does not have any special inputs to accomodate front/rear/center/ect. Is it true that my EAX usless?
