While we're on the subject on KVMs, what do you guys do about audio?

Currently I have one computer connected to the AV receiver via TOSLINK (optical audio). The other computer is connected to the receiver via coaxial S/PDIF. When I switch computers I have to physically go to the receiver and switch between the two input channels. This presents two problems:

P1: Manual action required

P2: Only one computer can play sound at any given time

Ideally, I would want a S/PDIF mixer that can decode the two S/PDIF streams, add each constituent channel together, and then output that as a single S/PDIF stream to the receiver. But I can't seem to find this anywhere.

Most mixers I've found are:

1. Analog mixers

2. Pro audio mixing consoles that have a dozen input channels and 50 dials on it, with a price tag to match



I have played with Voicemeter for this. You can stream the audio back and forth between machines. And one of them is always connected to the speakers. And you can mix between the two as well.

Thank you! This is great.


I bought a cheap audio switch but it was terribly built and introduced a bunch of noise. Now I just use a USB dac and let a USB switch handle the switching. If I wanted to have both computers play audio at the same time I'd set up pulseaudio to do that.


Get a USB DAC that's connected to the same switched USB as your keyboard and mouse.
