Topic: Glitches when system audio plays on MacOS Ventura

Hello,

I have seen reports over here about this but buried in other threads:

On MacOS Ventura with the 4.08 driver, I get constant glitches in audio when there's a system sound playing (e.g. email notification).

The only solution is to switch to internal audio interface on the Mac Studio.

Is this a known issue and is there a possible workaround? I want to use my RME UFXIII to listen to sounds from the Mac Studio so switching the audio interface for internal sounds is a workaround but not a solution.

MacOS Ventura 13.6
RME UFXIII
Mac Studio M2 Ultra

Re: Glitches when system audio plays on MacOS Ventura

switching off system sounds would be another workaround.

Hmmm... not really.
Sometimes clients want to listen to Spotify tracks on the fly or YouTube videos for referencing.
It's really not viable- I am just wondering if RME are aware of this.

Re: Glitches when system audio plays on MacOS Ventura

Ah I see you mean audio from the computer, not system sound.
System sounds are these blings and peeps from the OS like email notification etc.
You can turn off these with the volumen slider in the system settings and still listen Youtube and all.

Your issue is then when software playback produces glitches.

Re: Glitches when system audio plays on MacOS Ventura

Yes, indeed - I would honestly like to keep the sounds as they are- turning off sounds takes me back to the terrible Windows XP DAW optimization routines, we should be past that by now.

I never had an issue with RME until now- I wonder if it's an Apple Silicon teething problem with the existing drivers.
Most importantly, I am interested to know if they acknowledge it. I've seen reports but no one touched on the issue.

Re: Glitches when system audio plays on MacOS Ventura

The problem is, the issue is not reproduceable.
Your interface connected to my MacbookAir M1 probably has no issues at all.
MadifacePro with 409 driver works fine here.
The issue is reported often and RME and Apple surely know about and try their best to get rid of it.
Hopefully the next Sonoma update will fix it...

Re: Glitches when system audio plays on MacOS Ventura

I've read in a blog post regarding live sound on stage, that you have to keep the buffer size at 256 or lower on Apple Silicon, otherwise there a great risk that some process which is involved in audio run on the efficiency cores instead of the high performance cores, which might cause glitches.

Can this be the reason in this case?

I have myself had issues similar to this with my UCX II, but not with ADI-2 DAC FS which runs in class compliant mode.

The issue is reproducible on two completely different systems here.


1. Macbook Pro M1 Max
2. Mac Studio M2 Ultra

Do you use a relatively heavy project when testing this?

The only common denominator is the RME UFXIII (and of course, MacOS)



I was hoping the latest MacOS update would fix it (13.6.1) but nope, still there.

This is what worries me the most, from what I see over here, this is being reported but I'm not sure if it's been looked into.

EDIT: One thing to note is that I have at least 5 other audio interfaces in the studio that do not have these issues that the UFXIII has on the same exact systems. We are talking from sub- 100 euro interfaces to mastering converter USB interfaces.

Re: Glitches when system audio plays on MacOS Ventura

Thats interesting.
What system extensions are installed on both your computers but not on mine ?
My M1 Mac is actually on OS 14.1 upgrade to Sonoma did solve similar issues to many users already...
You could compare the list and for a test exclude those who are only on your systems.
Or you post your list here and I compare.
There are 2 Libraries with extensions
MacHD - System - Library - Extensions : 609 files
MacHD - Library - extensions : 6 files

Save a List of Files from Finder
    •    Open the folder you want to get a content listing of and hit Command+A (Select All) followed by Command+C (Copy)
    •    Now launch TextEdit and pull down the “Edit” menu and select “Paste and Match Style”, or hit Command+Option+Shift+V.
    •    Save the directory listing as either a . txt or . rtf.

Re: Glitches when system audio plays on MacOS Ventura

Computer is not phone or tablet.... Using big.little for time critical tasks is asking for troubles. If not treated right.

What about switching little cores off? I am not sure, if it is possible on Mac.. I am on Win.  But if it is possible, it is worth trying...

Re: Glitches when system audio plays on MacOS Ventura

I am wondering if this is fixed in MacOS Sonoma.
I have updated to 4.09 with the same issues.
Just to give you an idea, say I hit a shorcut while I am on my DAW that is *not* assigned to anything, MacOS will play a sound indicating that this shortcut does nothing. Even this causes interruptions in audio.

The most frustrating thing is I've tried other interfaces (budget ones as well) and they don't exhibit this problem that my UFXIII has.

Has anyone had this problem solved with Sonoma?

Re: Glitches when system audio plays on MacOS Ventura

While Sonoma definitely improved performance the easier way to check seems to install driver 3.31 from here:

https://forum.rme-audio.de/viewtopic.php?id=38691

If that still does not work 100% try the new Safety Offset option 'Large'.

Installing this driver seems easier than installing a new OS. Note that you have to use the Recovery mode procedure as explained in the driver readme.

Hi Matthias,
Thanks a lot for the suggestion.
So I guess the strategy is to install the USB drivers first and *then* the Kernel Extension drivers?

Is Apple not discontinuing the Kernel Extensions anyway? Has this changed?
Sorry if I've missed something but I thought eventually we'd have to migrate to the non-kernel drivers.

hi. I use Fireface UCX with MacOS Ventura 13.6 on a Mac Studio M2 Max. To use the kext drivers, you'll want to uninstall the DriverKit client drivers first.

In my experience the DriverKit client driver did not perform well on Ventura and, in their own video, RME appear to suggest that installing the kernel extension drivers is the way to go at the moment. This is what I've done and it appears to work although ever so slightly less stable than Firewire was on my old Mac. Occasionally macOS complains that the kernel extension will stop working, in some unspecified date in the future, and I click to ignore the warning, and go on with my day.

You are correct, Apple is discontinuing the kext drivers but on Ventura they still work. The intent hasn't changed, but the change itself still hasn't happened, possibly because it's proving problematic for vendors (RME demonstrably being one, if this forum and their video is anything to go by)

You haven't missed anything. Eventually we'd have to migrate to Driverkit client drivers. We don't really know when. If I was buying an audio interface _today_, i'd look for a thunderbolt box.

Hope this helps.
