I have two computers with sound cards and would like to connect both of them to one set of digital speakers that has only one input.Right now I connect one output to the other sound boards input,which works fine if both computers are on.But would rather connect both directly to the speaker system.What do I need,can anyone help.They won't work with just a simple Y setup.Thanks in advance for your help.

They don't work in a Y configuration because both streams have separate queue points. You would need to pump both into a decoder, and have only one set come out that carried both sounds added together.
One thing you could do is pump one digital signal into one of the sound cards, and monitor both that sound card's sounds, and the digital channel. The digital output of that sound card should have both signals in its single digital output at that point.
It would be much easier, cheaper, and more practical to spend the few dollars and have a separate set of speakers for each machine, that is if you want to do it right.

Self powered digital speakers are not cheap.
Aside from that, it is not an answer to this particular query at all. He want the two sets of channels in, and two channels out, not four.
Use two centre tapped transformers, one for left and one for right and connect the single output coils to the powered speakers, and each PC to each side of the centre tapped input windings. Use the centre taps as the common earth.
Either pc will work normally regardless of the other being on or off. If both pc's are driving the system together you will get both subtracted from each other as the phases are different.
If you are able to wind your own transformers you could make them with three windings, or you could make a multiple op amp circuit.
This is for using sound cards with analog outputs, but I think this is the system you have?
Hope this helps, Peter
A simple opamp based virtual ground mixer with line input levels should do ya...look on google for audio mixer projects, lots of stuff out there :>)
