I have a Digital-to-Analog Converter (DAC) directly connected to my computer and want to also use it with my monitor (no USB port) which is connected to some other devices (such as gaming consoles). The monitor has a standard 3.5mm audio jack, but suffers from severe crosstalk.
In other words, I'm trying to connect the DAC to my monitor, then connect my audio device to the DAC. I can use the PC as a power source.
