Noswal Posted December 2, 2020 Share Posted December 2, 2020 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.

Administrators Hervé Posted December 2, 2020 Administrators Share Posted December 2, 2020 CodecCommander always required to be cached before, it never injected. Try to cache it from /L/E as per previous macOS versions. Link to comment Share on other sites More sharing options...
Noswal Posted December 3, 2020 Author Share Posted December 3, 2020 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? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 3, 2020 Administrators Share Posted December 3, 2020 Yes, see our FAQ section. To verify cache update, check presence of CodecCommander kext in Sysinfo->Software->Extensions; it should show there... Link to comment Share on other sites More sharing options...
Noswal Posted December 4, 2020 Author Share Posted December 4, 2020 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? Link to comment Share on other sites More sharing options...

Noswal Posted December 5, 2020 Author Share Posted December 5, 2020 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. Link to comment Share on other sites More sharing options...
