I know this is an old thread - but this fixed it when my BIOS lost my Catalina boot partition. Thanks!

I have sound via HDMI to my external stereo receiver. However, the USB sound device (headphones/mic) still doesn't work. I use this for Zoom meetings, etc. It shows up on the list of devices but...no sound output. Any idea as to how to get it enabled? Thanks!

I have two nearly identical machines. The only difference is that one pulls sound from the NVidia GT640 HDMI port, the other (this one) uses the Intel motherboard sound. Got the sound fix in this thread to work fine on the HDMI machine. On this one, no joy. First tried checking "FixHPET" in...

Do you *copy* AppleHDA.kext to /Library/Extensions, or *move* it there? Thanks :)

I know this is an old thread, but I've started seeing this line ("superblock indicates jumpstart record but this driver not loaded from this partition"), along with a few-second boot delay, with my Catalina build. Is the patch from the previous thread (10.13.1) still valid?

Excellent. Thanks again!

I can actually live with it as-is. So, should I just go ahead and export this configuration as-is (-> USBPorts.kext) or would it make any sense to delete all of the "unknown" ports first? Thanks very much for your help, much appreciated!

Per instructions, USBInjectAll.kext is in /EFI/Clover/kexts/Other; yes, I still have the recommended port limit patches in place - haven't saved anything yet (waiting to figure out what's safe to delete). Thanks!

@UtterDisbelief - Thanks very much. FakePCIID_XHCIMux.kext and GenericUSBXHCI.kext are not installed (see kextstat output). Also find attached the sections of the IOReg that you requested. Much appreciated!

Worked like a charm! Thanks!

I have never been able to get iMessage/Facetime to work on this machine since the beginning. Would deleting the iMessage keys that I see on the Info page possibly help me to get it working? Could one or more of these old keys be blacklisted on Apple's servers?

Hi all - Just getting around to getting this done after tweaking a sound issue with my Catalina build (now working). Most of the USB ports work on this machine, but I was trying to get this optimized, as there are a few that don't. I am up to part three of the original guide on page 1. See...

Does this work for HDMI sound also? Mine quit working on the update to Catalina.

Tried adding WhateverGreen as well. This did not fix the "no HDMI audio" problem, and in fact causes VirtualBox to crash the system.

Just installed Catalina. No problems at all with the install, but I have the same issue - have lost my HDMI audio, which worked fine under Mojave. Did the above, installed Lilu 1.3.8 and AppleALC 1.4.2 - still no sound, however. Any other thoughts? Thanks in advance!
