That is, of course, without resorting to purchasing a >stereo mixer (over-kill). You could prabably get by with making a simple passive mixer for each channel using 2 resistors like this: 10k-56k PC A >----/\/\/\/------+------> AMP | 10k-56k | PC B >----/\/\/\/------+ The optimal resistor values will depend on the output impedence of the sound cards and the input impedence of the speaker amps. Tiny 1/8th watts could be soldered to the terminals of a metal-covered phono plug. Of course there'll be some loss in volume, but encreasing the PC output volume may compensate enough. If not, you could try lowering the resistor values. If the volume ranges of each PC are highly mismatched, you can lower the resistor value of the weaker one. In any case, try to avoid going lower than ~1k for audio outputs and ~100 for speaker outputs.
