Hi folks, hope you can help. I broadcast live dj sets on Facebook & used to use a standard TRRS to RCA Camcorder lead in my Xperia Z3 to input stereo sound from my sound card. I have just upgraded to an XZ and the lead doesn't work - the broadcast is just using the phone mic for the audio Obviously the configuration has changed for the type of lead needed, but i can't find any spec info on the official Sony site....
