I'm in the process of building my first computer, and would like to be able to share the speakers I already have (Logitech Z-5500) with it and my older computer. I've looked into KVM switches with audio, but haven't come across any reasonable solution that will allow me to use my wireless keyboard/mouse as well. So, I'm thinking of going with separate kb/mouse, but that still leaves the speakers.
So, my questions is this - can I continue to use the RCA ports for my old computer, as I am doing now, and connect the new one using digital coaxial or optical/spdif? (The speakers and my new mobo both seem to have the digital coax/spdif capability.) Also, which of the two - coaxial vs optical - is better for sound?
The setup should work fine as long as you use only one computer at a time. And optical is always better than coax (or wired) - the difference may be marginal, but optical is better suited to handle interference.
