I assume you're talking about the line-out/headphone jack. I do not use that myself as I use audio over usb to my amp but as a test I've connected the the headphone output to the line input of my amp and been playing some Youtube playlist for the past hour. The audio works fine, no drop outs or artefacts.
I don't know how you use OpenCore 0.9.9 + stuff from the repo. The repo is on 1.0.0 and should be used as is. Not mixing in other kexts even if they are newer. It shouldn't cause any issues but for me in order to be able to troubleshoot we both need to run the exact same EFI with just changes to the config (serials etc).
I will keep this connected for now and see if anything changes. Personally I prefer using audio over usb and my amp can do both but headphone/line-out should work as well. So this a good test.
As a test can you delete your whole EFI and download the latest release and only copy over your serials/network mac address and such to the new config and try again? That way we'll both run the the same version of OpenCore and all accompanying kexts.
For now I attach the can not reproduce label as I really can't reproduce it. Which always sucks to solve issues people have. I need to be able to reproduce it else all I can do is guess.
Thanks for trying to reproduce. Yes I am talking about the headphone jack at the front. I've just finished doing a restore of Ventura and Audio works again as expected. I did make some minor adjustments to my EFI-config.plist. I still have a fresh Sonoma installation on an external SSD and I can run it with an 1:1 copy of your EFI on an USB stick so that we have the exact same baseline. Will test that later tonight and get back to you.
You're welcome! I always do my best and as long as I can reproduce usually can fix it or come up with some work around. I am running 14.5. beta 3 on my "vanilla" test NUC but that shouldn't matter much.
(My other NUCs are still on Ventura with Broadcom and kind of stuck there as I want the iServices and full disk encryption to work. While full disk encryption works in Sonoma with Intel wireless the iServices integration is almost non-existent. Still surprised Apple actually removed Broadcom support from Sonoma completely as it stops many old but still capable Macs from upgrading to Sonoma unless you resort to OCLP which has as downside you can no longer use full disk encryption.)
Apple wants to transition their Intel customerbase to Apple Silicon asap and as a "nice" side-effect they will kill our community unfortunately. I have a mix of Apple and Hackintoshes but I don't like with their new systems that you cannot change or expand anything in them. It's all soldered on that MB and if you want more RAM, GFX, etc. you pay a fortune.
Anyways back to the technical issue: I did boot my fresh Sonoma installation with your original EFI release from end of March. The only thing I changed was the serial, ROM, MLB and System UUID. Now interestingly the same issue occured but in a different way.
I will be staying on Ventura for now as this works fine. But thought this might be interesting for other people to know who are considering moving to Sonoma. Of course only if somebody can reproduce this issue.
Fully agreed!
As for the issue, I will try and think of what I can use here to use the mic in one app and also have audio coming from other apps. I do share movies on Discord from time to time where I need to use an aggregate device but that does work with audio coming from both the video player and Discord plus discord also using the microphone.

I wonder if it's a privacy thing or something like that? You could check in the Console app if there's any clues, it always happens after 30 seconds that might help in spotting it. It can display (filtered) logs in real time too. I don't have Google Meet but I will try and think of something else than Discord to test. We're talking Safari here?
Yes that's a good point (Console). I tried to check registers for the Audio device via IOregistryexplorer and also dumped the content of with alc-dump (part of AppleALC source) but didn't think of the obvious and simple. There was nothing obvious when the Audio went off. So it doesn't seem to be any registers. It seems that when the System Settings Audio panel for Inputs is open, Output Audio will stay on for a longer period.
For reproducing: I believe you just need any application that will continuously use the built-in or Line-In microphone for Audio Input. Facetime should work as well. But if you have a google email address (also required for YT) then just open any webbrowser with https://meet.google.com and login with your normal google account. Then start a new video conference (with yourself).
I would have loved to debug the AppleALC.kext but that seems to be a more complex effort and since Ventura still works I will opt for that for now.
Thanks for trying
When starting a meet with myself I can see the orange dot and some indication of audio behind my profile pic when there's audio picked up by the mic. Youtube kept playing fine on another tab but the audio quality degraded a bit. When forcing the headphone jack to use the max bitrate/freq the weird sounds (some kind artefacts) went away. Maybe this will help you too. It can be changed it in the Audio MIDI Setup
app.
Changing the alc layout could also be an option but I am not sure and there many layouts to try for our chip (235). Making a custom one just for this NUC is something I haven't gotten in to so I don't know if that's easy or hard. And it may be a waste of time if the layout has nothing to do with your audio dropping out or degrades in quality.
Adding the Debug Enhancer kext will give a lot more logs without having to get into debug kexts and verbosity levels right away, which may generate a lot of logs.
Ah at least you were able to reproduce. Good. I forgot to mention that I also already tried to change sample rates via Audio MIDI. It reacts similar as Audio / Input panel in that when you change the Input Settings or any of the Sample Rates, Output Audio goes back to normal for ~30 sec and then back to strange state. I did have a look at console output and compared with my Ventura setup. There is nothing obvious. coreaudiod reports deviated sample times (but only marginal) every minute or so and then I have a lot of error messages from runningboardd about a memorystatus_control_error. But they occur on both Ventura and Sonoma and don't seem to be related to the cause of the issue. The runninboardd messages occur a lot. I looked up on Acidantera and really RestrictEvents.kext should help to reduce these. But it doesn't seem to as I have it installed already. CustomMemory configuration could help, even though my Memory modules show up correctly in System Details, including Vendor ID, Tye, Serial Nr. etc. But as I said I don't think it's related to the audio problem.
Apart from a little distortion that went away after setting the bit rates. It’s not what you described. So I can’t reproduce your exact issue and I doubt it’s caused by the EFI. I would guess others would have chimed in too.
