I have used my 6-Core Late 2013 Mac Pro since 2014 and audio has been fine up until about a year ago. Every day or so, the audio would disconnect from my Bose Speakers. When I hit the volume up/down button, I see that little Circle with the / on the screen indicating nothing is connected.
I would have to take out the audio plug and plug it back in (sometimes doing it twice in a row). That always solves the problem. After a day or so, it would be disconnected again. I also tried Sony Headphones and experience the same problem. Any help would be appreciated. Thank you!
