Audio core keeps reinitializing

I am using Logic Pro X on a Macbook Pro circa 2012-2013. I am still on El Capitan. My mac has started reinitializing the audio core every few seconds. I cannot do anything in the way of recording or playback as it constantly interrupts Logic when I use it. I successfully updated the firmware for my Audient ID22. I also have a brand new USB cable from that plugged into the computer. I have pulled it out of my USB hub i've been using and tried it directly in both ports on the Macbook. And of course i have rebooted everything at least a couple of times since along the way.

Eventually I created a new version of the file I was working on, copying over all the essential parts I needed to continue. It was fine for a couple of days and now the problem has returned.

Thanks for any suggestions.
