Thank you for the response. I am not sure if the Sony produces stereo or not, but I read for mono the Y should split it. Yes the Y splitter has male plugs. Also, yes when I am in the program I have both bars green, however when the right is plugged in it's just static sounding. If I unplug it then I am back to just the left channel. If I unplug the left then it's just static with the right and nothing more. Unplugging one, as expected, results in that channel (green bar) disappearing.
