No sound on my Mac

05 October 2018

Switching the output sound device repeatedly (e.g., going back and forth between external speakers and headphones several times) sometimes kills sound output on my laptop (currently on OS X 10.13 High Sierra). To fix, restart the Core Audio services: 

sudo killall coreaudiod
Annoying, but workable.
