Chosen Solution
I updated my MacBook Pro 2011 with MacOS Mojave and was trying to apply the update today, and I’m surprised no audio device on my system, any solution please?
Note! My system is not supported in MacOS Mojave I installed it with this method: How to install macOS Mojave on unsupported mac using DosDude patcher
Did you install the correct patches on the patch updater? I have a hunch that you forgot to install a necescery patch. I suggest doing a reinstall of Mojave, just be 110% sure you select all of the patches you can when you first initialize Mojave. Update (11/03/2018) I’m pretty sure you forgot to select the “Legacy Audio Patch” to be installed on this step.
Reinstall Mojave and be sure to do it the right way. The creator of this patch has instructions on how to do this properly below. http://dosdude1.com/mojave/
I had the same problem here, and the fix is really simple. Just open the Patcher Tool from your Lunchpad, and then click “Re-Install all”. After the installation, you will be asked to reboot your machine, and voila. The sound is back.
I hope this help.
Basically you can’t use the auto update function or manually update via Apple as the update installer will wipe out your required drivers for your system. You need to stick with DosDude moving forward. While I sympathize with you wanting to run the latest and greatest MacOS there is a point in time you need to bite your tongue and just sigh ;-{ The highest your system will support officially is High Sierra and its best just to stick with it.
The simple answer - You should have not have updated to Mojave, there is a reason Apple does not include them on the update list. What you can do - Find a way to uninstall Mojave back to whatever OS you were running before. Can’t find out how to Uninstall?- Use an external speaker, it is the best you can do.

the only way i got audio to work on my macbook pro early 2011 is via upgrade from high sierra, first the driver is already working from High Sierra, and use the upgrade method. i cannot get audio working from mojave via clean install of mojave with post-install. hope this helps someone.
