That worked perfectly. I got headphone audio! Thank you guys so much!

Hi Jake,

I tried running that earlier, but wasn't able to get it to finish. I'm not sure how to get permissions to write to /usr/bin in order for ALC_fix to finish running. I tried changing all the /usr/bin references to /usr/local/bin in the install.sh, but I'm still experiencing static.

I rebuilt the cache per your FAQ post. On reboot, I confirmed that CodecCommander was loaded through System Information. However, I'm still experiencing static. I still have CodecCommander in the EFI/OC/Kexts folder. Should I remove it from there?

Hi Herve,

I copied CodecCommander.kext into /Library/Extensions and then rebuilt the cache using:

sudo kextcache -i /

and then rebooted.

I'm still experiencing the same issue. Did miss a step?

Hi,

I got Big Sur up and running using Jake's bootpack here:

Everything seems to be working perfectly with the exception of the headphone jack. It's just static when I plug in headphones. The audio icon changes to headphones, so I think the OS recognizes that I have something plugged in. I updated Lilu, AppleALC, and CodecCommander kexts and reset NVRAM. I'm not sure what else I can try to address this.

When I had Catalina on Clover, the ALC_fix worked. I'm not sure how to adapt that fix to OpenCore.

I can't attach my EFI folder since it's larger than 19.53MB, but it is mostly unchanged from Jake's guide with the exception of the three kexts I mentioned above.

Nevermind. Everything works now. I should have just used the included permissions.sh to refresh the files after copying EFI over. I must have made a typo trying to enter the commands through terminal. Thanks for telling me what I needed to check!

I made sure to also install Clover r5092 on the laptop and copy the same EFI folder from the USB installer to EFI on the laptop. Is there any way to check if these are properly installed?

Hi, I just finished getting Catalina clean installed using the Clover Guide and the E7440_Catalina boot pack. My problem is that I'm not able to start the laptop after rebooting. I'm able to boot up properly if I start up using the Clover installation on my flash drive. However, if I start up using the Clover installation on my laptop drive, I get stuck on the Apple logo and without a progress bar underneath. I tried my best to follow the post-install instructions and even tried out different kexts versions, but right now I'm stumped. Can someone please point me in the right direction?

I used gibMacOS to download Clover r5092 because I wasn't able to get the latest version to inject the ethernet kext during the OSX install.
