>Depends on the sound card - you'll probably want to conenct the line out outputs from the soundcard to some input on the receiver/preamp. I've done this with the SB32 and SoundBlaster Live cards if you need details of what cables are needed and what inputs to connect to the preamp inputs.

Hi Ed - Right now, the PC-speakers are only connected with a single output jack directly from a machine 'port' and a 'Y' connector split to the speakers. Let me check the back of the machine more thoroughly tonight to see what options there might be, see if I can determine what those other I/Os are...
