Hi, I was having similar issues with the mic and spotted your comment on the ‘ssl issues’ - so I did a fresh Ubuntu Mate 16.04 install, Kinect disconnected and no drivers, instead using usb mic & headset & audio jack - all installed from the console.
Did you mean ‘ssh issues’ ? As that’s what I’m seeing.
Running from console is (for the most part fine - a few things that seem to cause sound hangs) - but mic does stay up and listening for hours.
However, using ssh to login and run mycroft, the mic hangs after a few seconds.
Run it from GUI console and all is ok again.
