For a few months I have been facing a problem with my audio jack (3.5mm jack) on my Mac Mini late 2014 version - every time I reboot my computer, log out and log back in or turn off one of my monitors, my audio output device stops being detected until I replug it. Is anyone else facing such an issue, and if so - what steps can I take to fix it?

I am currently using Mac OS X El Capitan.

  • Does your audio output device use the standard 3.5mm analog signal, or do you use the optical connection? Please edit your question to clarify. – IconDaemon Dec 27 '16 at 14:56
  • @Ic I have updated the question - it uses a standard 3.5mm jack. – petergood Dec 27 '16 at 14:59
  • This might possibly be caused by the plug being detected as a fiberoptic cable rather than a standard 3.5mm. Have you tried cleaning out the port on your Mac? When this happens, could you post a screenshot of Audio MIDI Setup with the output device selected? – Timothy Mueller-Harder Dec 28 '16 at 16:17
