Only asked cos just bought an x-fi xtremegamer soundcard and thought,as u would expect like an xbox i could get 5.1 sound from the optical out on the card. Annoyingly crap that u cant because since I have an nforce 630 chipset on me motherboard I think its stopping the rear connectionsi.e. directly from the soundcard,analougue outputs from working,output is distorted,like its being over driven,at any volume. The front header panel output works sweet!!! but i want the back ones working cos i bought it for gaming. The rear...rear( Ive noticed my diction and phrasing is prob difficult to read!?!blame the rum)outputs and centre sub output dont work at all. Ive scoured the net for solutions,unplugged the front panel connection,used all the versions of the drivers,but still no F$%£*n joy
