the very same system has been rocking like a champ on the same mac under monterey (i never installed ventura), never had a single glitch; and i have no clue what to do to troubleshoot all this.
i swapped the different usb-ports, the adapters, and the cables - all to no avail.
everything seems to be authorized correctly, no error pop-ups of any kind; just a miserable and completely unpredictable performance. using another brand at the moment, impossible to do anything with this madiface.
any idea?

thanks in advance!

Try old Kernel extension drivers.

...you mean 3.28B? i did - exact same problem.

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

Hi, I'm experiencing similar problems on an M1Pro macbook with Sanoma 14.0 and a Digiface Dante. Once about every 10 minutes I get an audio dropout (sometimes two in one minute and sometimes it takes 20 minutes before the next, but on average that's it). I tried both the kernel and the driverkit drivers, swapped cables etc. I have two usb-c to usb3-b cables, both showing the same issue. However, when I connect to an USB2.0 hub, the device switches to USB2 mode and the problems disappear. Also, when I connect my Babyface Pro or FireFace 800 (yes, I still have that), they don't show this problem. Can it be a usb3 issue? I don't remember this to happen in my previous macOS version (Monterey) but it could be that it happened there once or twice too, sometimes it is hard to debug dropouts in a Dante environment. This time though I'm sure it's the driver and not Dante, as it happens with loopback inputs too (effectively bypassing Dante). Help would be appreciated, although for now I can live with using a USB2 hub ;-)

Hopefully others can reproduce this !

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

I am having an issue where I cannot get audio into Logic Pro using the V4.09 drivers and a BabyFace Pro. I can select the input, but no sound comes through. Input works in Ableton and Bitwig. When I switch to the older kernel extension driver, I can again hear audio from the BabyFace Pro inputs. Anyone else having this issue?

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

Hey @woutersnoei -- I can confirm that I had the same experience: using a USB 2 cable instead of the USB 3 cable included with my Fireface UFX III solved the drop-outs issues!

Is Logic Pro allowed to use the 'microphone' in macOS system settings (under privacy and security)?

Yes, I checked that first. It's also a fresh install of Sonoma OS.

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

USB drivers have been updated to v 4.10 as DriverKit and 3.31 as Kernel Extension. The new DriverKit driver reliably removes the Kernel Extension, so it is very easy to swap between these drivers and check which works better for you. That said CoreAudio works better in audio multiclient mode with the Kernel Extension, and if you set the Safety Offset to the new option 'Large' it behaves exactly like Apple's CC driver, at least in our tests.

Kernel Extension driver 3.31 also includes a slight performance improvement, so it is worth a try.

Hello!
I', having the same problems with audio stutters since the purchase of my UCX II 6 months ago.
I've tried every single option with drivers but no luck. I just keep getting stutters and kernel trap messages in console.
DriverKit behaves slightly better than kernel extensions, but problem is never gone.

Yesterday I gave another shot to kext 3.31 and its much worse than DK.
MBP M1 Max
Sonoma 14.2.1

Any tips on how to possibly resolve it are much appreciated

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

We do our best, but we can't make wonders happen. When a system is so crooked up that a Kernel Extension driver does not only not help, but operates worse than DriverKit, that system seems to be ready for excorcism...

Seriously, contact someone with knowledge who has direct access to your computer, like our suport stuff or local guys. The forum can't help.

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

I think after many months of struggling, I have found the reason why it's happening.
When I have opened discord, audio stuttered when Continuity Microphone popup appeared.

I tried to disable continuity camera on my iPhone and voila, not a single dropout all day!

Apparently macOS from time to time checks if iPhone is around for continuity capabilities and this causes dropouts when audio devices list gets update.

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

That makes sense. When my iphone is around is sometimes pops up as an alternative for audio!

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

Hi, I have been using old Babyface for 10 years. I didn't have any problems with the interface and suddenly my M1 MBP Monterey dont see the Rme interface. Then I tried with new drivers but nothing, flash tool doesn't want to update. Does anyone have the solution for this problem?

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

I'm having performance issues and drop outs with the driverkit version (Babyface Pro) I tried installing the kernal extension instead but the babyface pro isn't detected at all when using that, so I had to switch back to driverkit, any reason why?

Worth checking if the kext installed at all. You'll have to follow RME's instructions to the word when installing the kext, including relaxing system security settings. After that go to the Apple menu and, where it says About This Mac, hold the Option (Alt) key, click on System Information to open the System Profiler, go to Software > Extensions and verify that you have an RME driver entry, that is both Notarised and Loaded. Hope this helps.

Re: Mac USB driver for macOS 11 & Apple Silicon hardware

- Reliable uninstallation of the RME Kernel Extension under Monterey (12), Ventura (13) and Sonoma (14).

I don't know what RME call "reliable uninstallation" but after upgrading to Sonoma the Kext driver was disabled, and then when I tried the DK driver instead, along with the Kext, it managed to mess up my Sonnet hub and not install the DK driver.

p.s. and the interface wouldn't work till I unplugged it from power and plugged it back in. Reinstalling the drivers made it stop responding again on the next restart.

p.p.s and again it fails the basic test where if I have a bunch of large images, attempting to quick-view them while anything is playing out of the interface causes drop-outs.

I'm not sure I have much patience left for the tiptoeing it takes to make these drivers work. Surely I'm not alone?
