The other week I plugged in a load of old speakers into my PC and got 5.1 surround sound working (front, centre & rear speakers.). I love listening to Alice Cooper on Virgin Classic Rock in the evening which I've got thru line in on my PC. Unfortuanly it only plays out of my orginal set of speakers ("FRONT").

Does anyone have any idea on how I can get my digital radio (plugged in through a cable in the "Line Out" of the radio and put into my "Line In" on my computer) to play through all of the speakers? I know it won't be in surround sound, but getting it through all the speakers would be nice!
