Boot Chime Time!

Changes from previous EFI:
  1. Updated some kexts
  2. Enabled Boot Chime
Enjoy

As usual remember to fill PlatformInfo section with your own serials

Thanks for this.
Apperaciate your hard work for community.

There is missing Starting angular bracket ('<') on line number 1614.
I tried after that but on my Lenovo Z50-70 no boot chime.
Any suggestion?
I was using GUI for Open Core previously.

I am gonna check the missing <
You have to download resources from OC's GitHub and full the proper folders to enable GUI and boot chime

EFI with fixed (typo) config.plist attached

Next EFI will use MacBookPro14,1 because MacBookAir6,2 won't be able to run Monterey

Yes, I tried that but didn't get success.
First I got "IOHDACodecAddress" which is 0x0
Then via gfxutil I got path which is PciRoot(0x0)/Pci(0x1B,0x0)
and then updated my 'config.plist' as described in the guide. but didn't work for me.
Can you please check the screenshot?


Yeah, I was searching for the same from yesterday. I got 1 extra partition for the experiment So, I was thinking let's try Monterey.
Set AudioOut to 1
Set PlayChime to Enabled
Make sure AudioDxe.efi is the first entry in the Drivers section
also check you have AudioDxe.efi in /EFI/OC/Drivers

Is your laptop configured for multiboot? Mine is and I noticed the boot chime is missing when I boot after using windows or linux.
I'd try cleaning NVRAM
Yes, I'm having
Windows 10, Mac OS Mojave, Mac OS Big Sur (11.4) and Mac OS Big Sur (11.0) on different partition of HDD and SSD.

But most of I'm using Mac OS Big Sur (11.4).
