linking an av receiver to a pc sound card got a evga 680i board with 7.1 out on the back and im trying to link it to my av receiver but cant get all the channels working. the front two are fine and the sub seems to be working just the centre and rear arent. the way i have it if the green output (fr+fl) channels on the card are going into the input on the av unit and all the speakers are correctly inserted into the receiver but it wont output to the rears and centre, its in 5.1 mode and so is the card., has anyone successfully done this before and if anyone knows where im going wrong please feel free to put me right. ta
