1. Download the appropriate version from the Releases and extract the zip file. Let’s assume that you downloaded “ALCPlugFix-Swift-RELEASE-1.5.zip” to download folder, and extracted the zip file in the same place (by double-clicking). You would have a new folder “ALCPlugFix-Swift-RELEASE-1.5” created. Right-Mouse-Click on the new folder icon -> Services -> New Terminal at Folder. A new terminal window would be opened at the current folder path: /Users/YOURNAME/Downloads/ALCPlugFix-Swift-RELEASE-1.5 (You can type “pwd” to verify it) 2. Copy the edited sample.plist file (in this case: ALC295-DELL7400.plist) to somewhere safe. I placed it in “Monterey HD\users\shared”, where Monterey HD is the name for my macOS drive. You may have a different name. 3. At the terminal (opened in step 1), type: ./install.sh Follow the instruction. When it asked for .plist file, drag “ALC295-DELL7400.plist” icon to the terminal, from the location you stored in step 2 above (in my case, it is from “Monterey HD\users\shared\”). You may encounter message like "ALCPlugFix is from unknown source” (1st time install) , just ignore it. After install is completed, go to folder: /usr/local/bin (this is where ALCPlugFix is installed). Right-Mouse-Click on ALCPlugFix icon -> Open, then Open again to allow it to run. This would give it the permission to run. Add "alcverbs=1 alcid=77" to the boot args. Reboot.

Check my post here, regarding using ALCPlugFix-Swift.

This appears to have the right method. I added "alcverbs=1" to boot args and used alcid=77, this brought me closer to make the audio fully working. Based on comment I learnt from another forum, issuing "alc-verb 0x19 0x707 0x20" successfully made the headphone port working. All I need to do is make ALCFPluFix doing the same automatically on Connect/Wake events (may be more), but I am not sure how to convert "0x19 0x707 0x20" to equivalent format for ALCPlugFIx. The author provided no details. May be someone here can help. Update (2/23): I got it working. All I needed to do was to modify the "param" value to "0x20", and set "On Connect" & "On Wake" to TRUE. The verb command "SET_PIN_WIDGET_CONTROL" is actually "0x707" in hex. I've attached my modified sample.plist bellow. Just follow the install instruction. During the install, it would complain that "ALCPlugFix" is from Unknown source, just ignore it. After install, I went to install directory (/usr/local/bin), and run it once manually, by granting the needed permission. ALC295-DELL7400.plist.zip
