As space is limited in my sons room he feeds his xbox sound & video through and AverTV card on his PC. For xmas we installed an Aureon 5.1 sound card and a set of Altec Lansing active speakers. Sound from PC games and Dolby Digital DVD's is fantastic. I also bought an MS adv SCART with opitcal as the Aureon has Optical In (and out) connections as well as traditional line in/out etc. So xbox->Advanced Scart->Optical cable-> Aureon 5.1 Fun card-> analogue to speakers Unfortunately I cannot get any xbox sound from the PC speakers when it is all hooked up. Has anybody got an Xboc running through a PC sound card using optical ? If so how? PS The Aver TV card doesn't touch the audio in this scenario..
