MultiBeast 8.2 fails to install RealTek ALC1150

Using this guide and hardware: http://www.tonymacx86.com/threads/guide-el-capitan-on-the-skylake-h170n-wifi.178197/

Up and running. Graphics, wifi, USB, SSD are all functional.
However, Multibeast is failing when I attempt to install the RealTek ALC1150 with nothing useful in the logs.

Multibeast Log:
07/26/16 08:09:57 - Mounting EFI

I was able to manually install the .pkg in the /resources directory, but this did not solve my problem [no audio output devices detected]. When I rebooted, and attempted to install the .pkg again, it failed.

Log entries are missing as there is no messages from the postinstall script. It always prints messages on why it fails or what it did.

Made a more verbose log file and shared on original post.

Note, the original included this section:
Jul 26 16:45:22 Seans-iMac installd[293]: PackageKit: Install Failed: Error Domain=PKInstallErrorDomain Code=112 "An error occurred while running scripts from the package “Clover-ALC1150.pkg”." UserInfo={NSFilePath=./postinstall, NSURL=file://localhost/Users/seantaylorseyer/Desktop/MultiBeast.app/Contents/Resources/Clover-ALC1150.pkg#kextstopatch.pkg, PKInstallPackageIdentifier=org.tonymacx86.cloverAlc1150.KextsToPatch.pkg, NSLocalizedDescription=An error occurred while running scripts from the package “Clover-ALC1150.pkg”.} {
NSFilePath = "./postinstall";
NSLocalizedDescription = "An error occurred while running scripts from the package \U201cClover-ALC1150.pkg\U201d.";
NSURL = "file://localhost/Users/seantaylorseyer/Desktop/MultiBeast.app/Contents/Resources/Clover-ALC1150.pkg#kextstopatch.pkg";
PKInstallPackageIdentifier = "org.tonymacx86.cloverAlc1150.KextsToPatch.pkg";
}

which seemed to be the relevant part.

The answer why it's failing can be seen in these lines:

Jul 26 16:45:22 Seans-iMac installd[293]: ./postinstall:
Jul 26 16:45:22 Seans-iMac installd[293]: ./postinstall: No Clover ESP Found Exiting
Jul 26 16:45:22 Seans-iMac installd[293]: ./postinstall:

Well, after mounting the EFI drive it installed correctly, though it was mounted for my last attempts so I'm not sure wether or not installing the .pkg changed it or what.

Anyways, my audio still isn't working but I suppose that's inappropriate for this thread since technically MultiBeast "installed" it.
