Volume not recovering after a FaceTime call Not sure if this issue started with High Sierra or Sierra, but definitely have been coming across this issue more and more often.

Like it or not, FaceTime ducks the volume of every other source during a call. And sometimes, after clicking the hang up button, volumes are not restored back to normal.

Is there any way to force this back to normal? Restarting an audio service maybe? I'd prefer not to restart the whole system every time. Thank you.
Quit coreaudiod:

Open app Activity Monitor (Utilities -&gt; Activity Monitor in your applications folder)
Search for &quot;coreaudiod&quot;
Click the (x) in the top left corner and quit the process normally.

It should restart automatically and if you hear no sound, restart the desired application. Note: All applications already playing audio might have to restart as well, not sure.
Warning:
Be aware if you've turned up the volume to max in frustration of the low sound. It might break your speakers or cause permanent hearing damage. I take no responsibility for following this advice. Consult with your IT technician before moving your curser.
