Noise on Jack about lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore HOT 13 CLOSED

The workaround seems to be broken again. So the only fix is the sleep wake trick

yes only sleep wake trick,

from lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore.

I found a fix that worked for me, on Big Sur 11.2.3 on my T450.
The newalcportfix didn't work and i still had noise, as others have reported.
What I did:

1. I removed the install of the newalcportfix (included in this repo), including the /Library/LaunchAgents/com.dark-dragon.....plist
2. Applied the alcfix from this thread:
   https://www.tonymacx86.com/threads/opencore-mojave-installation-on-lenovo-thinkpad-t450-howto-fix-audio-problem.303545/
3. Enabled codeccommander in config.plist (changed enabled=0 to enabled=1)

Thanks. I'll test it then add it to the repo

I also fix the noise of the earphone with CLAY, install the BIG SUR after installing the BIG SUR, and the headphone noise problem is solved.

There is also the latest driver of DW1820A, don't need to be injected, this can be updated.

Din't work here, just executed the install.sh and restarted: same noise on headphone jack.

Do I need to copy anything into de EFI partition for this to work?

Don't need other operations, you can perform the installation script.
CodecCommander.kext needs to be loaded in config
Or try RESET NVRAM

Ok, i've enabled the codeccommander and now it does not boot, says : missing injected kext... now I don't have another pc D:

from lenovo-thinkpad-t450-t450s-hackintosh-guide-opencore.

Ok, solved it! I was lucky to have a backup flash drive with the default EFI init! I've added the missing kext to the folder and the headphone jack is working fine now!

PS: 10 minutes of pure terror until I found the flash drive...
