  1. This has been happening with my 2018 Mac mini. No amount of fiddling with System Preferences or System Information addresses it. A restart fixes it, but of course is tedious and aggravatingly time-consuming when necessary to do repeatedly. A faster fix is to enter “sudo killall coreaudiod” into Terminal.

    Now, if I could only solve the “video not playing” problem…
