No. No agregate devices.

Will also note that after using a stable build (3.28) for the last week, I didn't have any issues. It does seem to be the beta.

I am very new to Mac and I have no deep insights in driver coding or the OS, but I did not have the same problems with glitches before this version 4.06 so I agree that is seems to have a connection with the beta on the M1.

Is there any experience with the driver on Mac OS Ventura? Is a compatibility patch planned in the near future or does the 4.06 run without problems on Ventura so far?

Yes. I am running Ventura 13.1 on a Mac Studio and the playback of audio stops and produce silence for a few milliseconds randomly. This is most prominent for me when looking at Youtube shows, but happends in other programs as well. Not so much in Cubase. My theory is that I listen to shorter chunks in Cubase before I stop playback to make edits. I find that this problem gets worse with time. The longe I have hade the 4.06b the more this problem manifests. I did not notice it with 4.04. The best way I can describe it is like there is some kind of buffer that fills up with time. I am seriously contempation removing 4.06 and going back on 4.04.

Trank you for your reply. I'm still on macOS 12 with my MacBook Pro M1 Pro and currently have no problems with the 4.06b driver for my UFX.
I'm just slowly considering an update and wanted to know if this is possible with the beta driver or if there will be problems.
The 4.06b is now also a while in beta testing and I was curious if there will be a 4.07b or a rc in the near future?

I think it is too much to call this absurd, but I also find it a bit surpricing given my long experience with great driver support from RME over many years that this problem can not be sorted. I assume that RME have a professional connection with Apple to solve this. But If it indeed is a problem caused by Apple and Apple ignore RME I would like to get a good description of this case so we can all send that request to Apples support and kick the ball over to get this solved.

Do you also experince that this problem of silience gets worse everytime you use it? Just now I tried to look at an episode of BadGear on Youtube. The first minute was fine. in the seconds sound was lost twice in the third minute it was about 5 to 10 times of dropout and int the forth minute I gave up it was dropout in sound every five seconds or so. Safari and sound does not work well at all any more.

@BlackBlossom
If you have problems with the beta driver, why not just use the current and working one from the main site?

Anything is possible, but since there are more of of having this problem, that we did not experience before using older MAc OS and older drivers the logical conclusion is that there is something wrong with either the newer Mac OS Ventura or the newer RME drivers. I have this can be sorted out reasonably soon or I also feel I have to move to another platform. My first step will be to downgrade my RME drivers today and see what results that give me.

Ok, Matrix. I have not noticed any alert sounds interfering when I have lost playback. If disabling alerts help I could have tried that, but I just reinstalled 3.27 driver again and so far it seems ok, but on the other hand I did not experience the problem on 4.06 in the first days either so time will tell.

I already mentioned in an earlier post that I also own an RME Fireface 800 and it runs perfectly fine with that! Same computer, sessions, plugins etc.  So the problem is with the USB driver used by the Babyface Pro FS! I also borrowed a UA Apollo Twin from a friend and it works absolutely fine! I am not not the only one complaining so obviously there is a problem!

Here you go MC! you wanted proof! Here's some more. Its not an isolated issue! Its a problem with the USB driver in general.

Well, I didn't come up with the Audient example but I thought it had drivers. My Bad. People I know with other interfaces have no problems at all. My knowledge of coding is limited so I will not comment on the firewire driver, but that was intended to be a feedback that things are perfect on a really old device! At the end of the day I am not here to challenge anyone, but to find a solution for my problem. I paid for an RME device and expect it to work which it doesn't because of this diver issue. I have contacted support as well but got a very rude reply. Hope to get a solution and some professionalism from RME soon.

Actually, come to think about it - This is my last post here, please delete this account and all associated posts.

In https://developer.apple.com/documentati … verkit_sdk apple clearly states:
Important
DriverKit doesn’t support USB devices that manipulate audio or that communicate wirelessly over Bluetooth or Wi-Fi. For those types of devices, create a kernel extension using IOKit.
Am I missing something or RME driver doesn't manipulate audio?
Does it mean that RME USB driver using driverkit is doomed?

If they have to re-write the code then so be it. Or they should mention on the website that they don't have a working USB driver for Mac so that people don't buy a new device and get stuck! Its been too long now since this problem started! Apple is not going to change their stuff for one company! So like other companies have found ways to deal with it, so should RME!

Oliverr , no I did not do anything but sit and watch a few episodes of BadGear and sound got more and more glitchy all the time.... But I saw a few system notices from apple about Apples clods service(which I have not enabled cause I prefer to keep my files local). That was the only "interaction" going on.

Lets hope Mac know about it and can/want to fix it. Are you a Mac developer? If you feel like it please try and build and M1 installer for SynEdit. https://github.com/SynEdit/SynEdit

I am not sure, if this is an issue of the RME USB driver, but I've had some strange behavior twice last week: in the middle of a online meeting suddenly a few seconds of my voice stream did an infinite loop. First I thought, it was this buggy Slack app, but a day later it was with Skype too. It happens randomly. As Skype and Slack are two fully different apps, it must be something used by both apps. Apple sound / usb driver? RME USB driver? I will observe it …

Hi Tigersoul. I recently downgraded to get rid of the dropouts so I am on 3.7 driver now. RMEusb and Coreaudio does not show up in my activities and Totalmix show 1,9% on my Mac Studio M1 when idling like I am now.

So, essentially, the cpu usage was just hidden under another name. I noticed though that most of my cpu usage came from having reverb on. I didn't realize it was even on. Turning it off, lowered the usage. Quitting totalmix lowered a little bit more still, but it's still not zero, but perfectly tolerable.

What surprises me is even disconnecting the interface completelly leaves a little bit of cpu usage from com.apple.DriverKit.AppleUserECM of 0,4%.This is not much to write home about but I still don't get it why cpu is used for a driver that is not connected to anything.

I assume, from the info above, that this 0,4% would just hide under kernel_task instead if I downgraded? correct?

Hi, just my experience. I have been using the 4.06 beta with Monterey for about 6 months with absolutely zero issues, on a M1 MBP with Logic, and a madiface USB connected with a CalDigit TS3. I had to update to Ventura for various other reasons, and since then I do get some pops and clicks on playback of Logic files sometimes, but Im pretty sure its something to do with other parts of the OS intefering in some way with the RME stuff? For example, when I updated, a bunch of notifications got set to ON by default, and whenever a notification came up, I would get a small audio glitch. I have turned them all off (I think) but I sometimes still get glitches. One way to "force" a glitch is to swap apps to something like Brave or Safari while playing a file in Logic. If I have something like youTube open in the browser, I will get a glitch when I switch apps. Now... Im not suggesting you should be doing this when making audio, but it does seem odd that I never had this problem under Monterey. Its like the whole structure of audio priorities is somehow different in Ventura? I dont know. Anyway... it doesnt feel quite as solid under Ventura as it did under Monterey.
Likewise, something else I used to do a lot under my INtel system with the old 3 driver was have ABleton and Logic open at the same time and use loopback to run ableton stuff into Logic. (both using the RME Madiface as their interface). this seems much more precarious under Monterey and Ventura with the 4.06 than it did with the 3 driver and Intel. I get pops and clicks quite often in this setup.

thanks @mattrixx - yes thats kinda what I suspected. I wonder if its something Apple might resolve one day.... or of they care :-/

This is not true when using the 3.27 driver. After downgrading to 3.27 I can click the systemsound play like hardtechno 300bpm and not get a single glitch. So it must be some combination of the 4--xbeta driver and Ventura OS. It is not a universal Mac OS problem. My Mac Studio works good with my RME802 now when I am back on 3.27.
