I'm searching for the product that can receive signals from external DVD player / VHS Player. I have Intensity Pro 4K, which can take composite connection too (so to use VHS player too) to send it to my PC and makes PC as television. I have been using IP4K otherwise to capture input taking only. If composite sound output is simulataneously connected to audio amp, is it functioning like television or monitoring sound at the same time with video input?
