It's working, no problem.
Sure? Ever since Big Sur I could not get HDMI audio working on my Nvidia 780 graphics card.
On Mojave it did work when I quickly power cycled the monitor during booting. But since Big Sur it is gone.
NVIDIA Kepler cards are not supported since Big Sur, so, OCLP is injecting Big Sur drivers to newer releases and this have adverse effects.
OK, I took a chance and just let my MacPro upgrade to Sonoma 14.6.1 this evening.
And to my surprise... HDMI audio works again!!!
At this moment the machine is a bit slower. iCloud, TimeMachine and Photo-analysis daemons occupy all CPU's very much. But is looks good so far. I let it run for a couple of hours and run Onyx to clean things up later.
You are in luckm, I just used this to back level to Sonoma 14.3.1 as a bunch of files got encrypted at 14.4 which destroyed my airtag app. enjoy: https://archive.org/details/macos-14.3.1-usb-installerAn update: this little trip with Sonoma 14.6.1 on my MacPro 2008 has ended. Even though I hardly used it, Wifi didn't work anymore and the suggested manual patch didn't work. But the biggest problem was bluetooth; after a couple of seconds I didn't touch the wireless keyboard or mouse, it lost the connection causing an annoying 2-3 second delay before I could type again. I tried a fresh clean install instead; problem remained.
Also the HDMI audio was lost again after just one reboot/shutdown.
I wanted to try Sonoma 14.3.1 because that version still had the Broadcom wifi support, unfortunately the full installer of this version is already removed from Apple's servers. Maybe someone here on MR has a private link where I can download?
Anyway... I'm now in the process of reinstalling Ventura again to have a working Mac again for now.

This is a personal app that I developed using some apple data that's on my computer.Man... how can that destroy an AirTag app? Or is it a 3rd party app?
It's been a few weeks now since I've got Ventura fully restored (including all the data from the last TimeMachine backup). Even HDMI audio is working permanently. The newer OCLP (2.0.2) did solve the crashing when the MacPro went to sleep-mode (basically freezing the machine). This was solved by disabling mediaanalysisd. That also fixed the crash right before power down during the shutdown sequence - I always had a message that the machine had crashed when I turned it on.
I'm keeping the machine on Ventura for now, but I'm monitoring the OCLP pages for any developments. Maybe... just maybe I can upgrade to Sequoia some day.
