How to make sound work again in a MacOS without a reboot

Sometimes, sound output in a MacBook laptop is gone. To restart the sound driver, kill the coreaudiod service - it will restart automatically and sound output will be restored:

John-MacBook-Pro:~ eyal$ ps -ax|grep corea

81524 ??         0:00.08 /System/Library/Frameworks/LocalAuthentication.framework/Support/coreauthd

82158 ??         0:00.35 /usr/sbin/coreaudiod

82163 ttys001    0:00.00 grep corea

John-MacBook-Pro:~ eyal$ sudo pkill coreaudiod

John-MacBook-Pro:~ eyal$ ps -ax|grep corea

81524 ??         0:00.08 /System/Library/Frameworks/LocalAuthentication.framework/Support/coreauthd

82167 ??         0:00.30 /usr/sbin/coreaudiod
