Installing the ALC 898 on macOS Sierra.

[sepoto]

I read the sticky that says to mount my EFI partition and run the ALC-120 script to enable sound on my Gigabyte UD7 running GTX 640 graphics. On a fresh installation of macOS I mounted the EFI partition with diskutil mount disk0s1 at the terminal and ran the script selecting the ALC898 hardware id 1 options since my motherboard uses a six port onboard sound device.

Upon restarting my machine I found that still no onboard sound was being detected by macOS although in a previous installation I had got the sound working with the same ALC-120 script.

I have been noticing that the installation script causes boot problems for me. As soon as the ALC 898 kexts go in the system will boot to macOS only intermittently and frequently I get the white circle with a slash through it when clover is booting.

Is anything known about what to do about the types of things I am experiencing?

P.S. I did look at my clover configuration after the running the 120 script and saw that PID was completely disabled not just partially.

PID was completely disabled not just partially

Script does not touch PID, that problem is somewhere else.
