RME User Forum → FireWire & USB series → UFX III crashes Zoom on Mac
I was using a gen 1 UCX, then a UCX II and I just added a UFX III to my studio…and love it.
However, the UFX III crashes zoom when I select it….
Steps to reproduce:
1) Have Total Mix/UFX III up and running
2) Open Zoom
3) Select Audio Settings
4) Select Fireface UFX III as Speaker
5) Zoom gives a beach ball until I force quit it.
Any suggestions besides not using Zoom? :-)
Thanks!

Support got back to me in minutes, I was shocked and thrilled!
It has to do with channel count, I substituted a USB2 cable for the USB3 and it worked great.
Hopefully it gets fixed soon so I don't have to be swapping cables.
Having this exact issue too. How are you getting past it now?
To make it more clear - there is nothing to fix for RME. It's all on Zoom and Apple to fix channel count limitations.
I imagine you could work around this limitation by using Rogue Amoeba's Loopback
https://rogueamoeba.com/loopback/
Is there any workaround for this?
I was having an issue with the totalmix gui turning to tv static when coming out of sleep. Was instructed to update drivers and now totalmix crashes zoom which wasn't happening before I was instructed to update drivers. Now the totalmix gui is still static when coming out of sleep and it crashes zoom.
So I have two problems and support has gone dark. Not a great experience...
Post number 4 did clearing.

Could you please shed some more light on this? What channel count do you mean? I hit exact same issue with RME UFX+ and I'm using USB3 cable. I would love to make a proper report to Zoom support, but I don't know what exactly should I refer to?

For what it's worth, this issue showed up for me when I upgraded to the driver from 2023-11-16 (driver_usbdk_mac_409.zip) and went away when I downgraded back to the one from 2023-05-12 (driver_usb_mac_328b2.zip).
My OS (14.1.2) and interface (UFX III) remained the same.
This is a bit disappointing. One of my reasons for purchasing UFX III over UFX II is to use the higher channel count for loopback paths in multi-app production and streaming. I have the same freezing issue trying to access and change audio settings in the Mac Zoom app (Ventura). I installed only the DriverKit RME driver and do not wish to regress to KEXT.
While I understand that Apple and Zoom need to sort this out, can RME possibly help make this issue a higher priority for those companies? It's silly to buy a USB3 interface only to run as USB2. I actually cancelled my UFX II order and upgraded to UFX III; now wondering if I should have stayed put. I will try the USB2 cable and see if this solves the issue for now, thanks.
Well I've tried switching to Audio Hijack or Loopback I/O in Zoom audio settings but the app freezes the moment I open the Settings/Audio tab. Yesterday I needed to Zoom via iPad with no better solution until I fix this.
Jeff has suggested switching the UFX III to USB2 mode or using a USB2 cable for connection; either should drop the MADI channels from the USB driver and fix the Zoom problem for the time being.
I assume that USB2 mode is Class Compliant which also disables some hardware settings and TotalMix functionality, so I would rather not do this.
I've tried connecting from the lower half of the UFX III Type B port to the Mac Studio USB A port using a USB 2.0 B/A cable, but the Mac does not detect the UFX III when I do this. I'll try again but want to make sure this is supposed to work.
I'm using the DriverKit 4.0.9 driver and really do not want to install the KEXT driver just to fix this problem.
All suggestions are welcome, thanks.

I tried again this evening with the USB 2.0 B/A cable and got 30in / 30out mode working with Zoom.

An update with this. I updated to the latest Kernel Extension Driver (driver_usb_mac_331.zip) and everything works perfectly with Zoom again.
(I couldn't install the DriverKit version as the "Terminal" step threw an error and just didn't work after restarting so can't comment on that one).
Thanks for your report Rodrigo. I've suspected the issue may be DriverKit only. I really want to avoid reverting back to KEXT unless absolutely necessary; thankfully the v409 driver seems to be working well for everything else here.

I can confirm that using the latest Kernel driver (331) on Mac fixes this issue. Whereas using the latest Driver Kit driver makes Zoom crash.
Aaaand back to the same issue here. I moved from the KE (331) back to DK (410) since I was having consistency issues with the KE version dropping out. Has anyone found a workaround for using the DK driver without Zoom crashing?
What does 'dropping out' mean?
I made a separate thread about it a while back:
https://forum.rme-audio.de/viewtopic.php?id=38850
Essentially the UFX would spontaneously stop passing audio, several times a day, and would only start working again if I manually selected another audio device in system preferences and switched back to the UFX.
