ALCPlugFIx is required to fix static noise on headphones, however Black-Dragon74 released a Swift version that doesn't require hda-verb, alc-verb or CodecCommander kext.

Note: If you are using the old non-swift alc_fix please uninstall it first;

sh uninstall_old.sh

Installation:

• Open terminal and type following commands one by one on the listed order:

sudo spctl --master-disable`
sudo mkdir /usr/local/bin/`
cd to the ALCPlugFix dictionary`
sudo cp -R ALC3232.plist /usr/local/bin/`
./install.sh

• Now the installer will ask you to drop the ALC3232.plist into the terminal window.
• Open a new finder window and press Shift + Cmd(Alt) + G to open a new go to folder: window
• Now type: /usr/local/bin/
• Drag the ALC3232.plist from the /usr/local/bin folder into the terminal window and press enter.
• Done

Note: Please disable the kext CodecCommander.kext from config if you're using this version of alc_fix
