Hi guys, just want to share something that I found online in case it helps anyone.

I have a Hackintosh running macOS 10.13.5, and occasionally the audio stops working and I have to restart it. This problem has been very annoying and I haven't able to find a fix for it. Instead, I came across two terminal commands that reload the AppleHDA.kext to fix the audio without restarting. Just type them in the terminal or place them in a .command file. It's not ideal, but it's much easier than restarting every couple hours.

Code:
sudo kextunload /System/Library/Extensions/AppleHDA.kext
sudo kextload /System/Library/Extensions/AppleHDA.kext

Freaking genius!

Just in case, I have the same issue, but I used to solve it sending my computer to sleep and then waking it up instead of restarting it.

That solved my issue too. Everything was fine until i upgraded to 10.14.4 and Multibeast 11.1.0-6. Now sound disappears after hibernation. Hoping to find a longer term solution but enlil's solution is better than a reboot to get audio back.
