You audio driver is in system extensions. If you lost sound output try a Nvram reset.Command-Option-P-R keys and power button for two chimes. Or SMC reset.https://kb.cvtc.edu/page.php?id=106679 You could also go to system preferences Sound and make sure mute is not checked. If all this fails, go to recovery and reinstall your operating system.
