I am setting up a computer for local listening within range of the scanners but also for setup to stream the two scanners SDS200 and BCD536HP connected to the computer. I have a 3.5 mm splitter connected to the scanner's external speaker port then have a speaker plugged into one end of the splitter and then the other is connected to the computer audio in. The problem is when I have the usb cable connected from the scanner to the computer and the 3.5mm cable connected from the splitter to line-in port on the computer even if I have one of them plugged into the computer I lose the audio from the scanner until I unplug them.. This is happening on both scanners. Any idea on how I can make it work?
