I have two Windows PCs and one audio amp connected to the second PC. I'm trying to hear audio from both, ie, share the amp between the two PCs.
I tried a regular mixer but I get hum and whine loud enough to be annoying.
I tried using a male-male 3.5mm stereo cable to connect line-out on the first PC to line-in on the second, then passing the audio straight through using "Listen to this device" in the microphone properties on the second PC. But just like with the mixer, I get hum and whine in the signal.
So I want to do it digitally. I figure I can probably buy a peripheral that will connect optical out from the first PC to USB-in on the second. But perhaps I can do it direct using USB? Does anyone know how?
