10.13.3 No sound internal speakers have disappeared?
Since the upgrade to High Sierra, internal speakers have gone from the sound preferences. An update to OSX since, did bring them back. Then another incremental update to HighSierra OS in approx December/ Jan 2018, they have vanished again.
I was expecting another bug update to fix these, however non of them have resolved the issue.
I have done resets, restarts - I do not have any Airfoil in my library.
Anyone have any suggestions as Apple have dropped the ball on this one.
