Sorry, there was a problem. Please try again later.I'm new with this camera and I'm not as much of a videographer but I consider myself a hobbyist. I bought a shoe mounted stereo microphone, ECM-XYST1M and ECM-W1M and when I'am recording at 4K the screen indicates 2 ch. When my settings is in lower video quality then the 5.1 channels activities. Never tested the audio quality output when I was using microphones in post production to check if the 5.1 audio worked. I would suggest calling sony directly if 5.1 audio is a must for your purposes. Hope this helps you or anyone a little bit.
