Is your mic volume low using AppleALC or not working at all?

cracky sound

In my case, mic volume is slightly low but otherwise its working fine.

Is there a way to get audio jack sensing to work using VoodooHDA?

daigosx,​

Were you successful with Big Sur? If yes, could you please validate the attached EFI for Big Sur?
Thanks

Here is my testing EFI for Big Sur… Without wi-fi / bluetooth driver. OC 0.6.2

You're right. It was the same with me. The problem was in the configuration - which was for AppleALC. Also, every time the entire OC is changed, NVRAM should be deleted - this is what you have to do when boot menu show. Now i tested. As seen above OC is 0.5.7 - built from source. Okay...

Thank you Mikorist!

Audio jack auto-sensing is still not working in VoodooHDA (tried the info.plist modifications) but it works perfectly in AppleALC!

Your guide helped me to get full graphic acceleration (with 2GB) but the brightness is always full after booting. Do you know how I could retain the brightness value between restarts or set a preset value?

Also, I had to do the following (now and then) to make sleep/wake work properly.

sudo pmset autopoweroff 0
sudo pmset powernap 0
sudo pmset standby 0
sudo pmset proximitywake 0
sudo pmset lidwake 0

Is there a better way to do it?

Thanks again

Yeah - to take the DVD drive out of the laptop ... in my case, that's the only way to make sleep/wake work properly.
Because optical drive leading to panic reboot:

I just realised you are using OpenCore. Is there a fix for Clover? Unfortunately I don't know of any Clover fixes but if there is any you'd have to look in "Kernel Patches" section and do some trial and error with different flags on and off "NON-PERMENANTLY" by turning on and off the flags in...
