In case you've not seen it, the driver has been released as version 1.08 and can be downloaded via RME website. There is an issue with the link of the driver file though:
it reads

so the domain and download folder is twice in the link so here is the correct path: https:/rme-audio.de/downloads/driver_mac_hdspdk_408.zip

It was on the driver download page:
https://rme-audio.de/de_driverKit-Info-hdspe.html

but it is fixed, the download of the driver just works now

After testing the 4.24 version on a Mac Studio the last two days, I've to say: Great work!
No issues with drop-outs, the latency reported is spot-on and (at least in my imagination) there is a lower base-line system load.
Why is that noteworthy?

• My AIO interface is 12+ years old.

• With expansion cards.

• It is sitting within a TB3 case.

Still in 2023 everything is working - even with new(er) stuff like the ARC USB.
Thanks for the ongoing support...

I did a lot of testing of the driver kit version 1.8 and unfortunately have some issues:
- there are still random burps and noise sounds (way less than the versions before though)
- switching between applications can cause clicking sounds
- Meters in TotalMix sometimes blink / flash

I tried with beta 3 and am now installing beta 4 - lets see if that improve things

edit: I obviously got that wrong, I was already on 13.3 final and the updater is offering 13.4 to me - but I'm not sure if I'll going to install that already.

I just edited my post (did not saw your reply) I was already on the release version and mistook 13.4 beta 1 for 13.3 beta 4

...does macos ventura require the new driver kit driver or is it still possible to install the old kernel driver?...

....thanks for your reply!...i didn't want to hijack the thread, i'm just wondering why everyone seems so obsessed with installing a beta driver when there is actually no need to do so...i'm on monterey and 4.24 works perfectly fine but i may upgrade to ventura in the near future so it's good to hear that 4.24 still works...thanks!

This is my thinking too. I'm normally not too afraid to try new software (I do a lot of beta testing for audio apps/plugins) but between the (in my opinion) complicated process of converting from the old drivers to the new drivers, and the reports of dropouts and performance issues with the new drivers, I'm not too interested in trying the new drivers right now on my 2019 Intel Mac Pro when it's working OK and I'm very busy.

My current plan is to just install the new drivers right away when I get either a new M2 Mac Pro when they are ready, or a Mac Studio. I will decide once the new Mac Pro is announced and more details are available.

I hope the new drivers are as stable as the old drivers by that time. Any reports on progress or findings from RME would be great.

The old drivers I have are amazingly stable. I've recorded thousands of hours of masters from my analog chain at 96k with some plugins running live and there is NEVER an issue.

In my case, it's the only way I can aggregate my 3 Multifaces with Cubase.

It will not work with 1.28, but under 13.3 you can flash back to the former firmware (Legacy) - then it will work again.

An official update on this from RME would be great. RME drivers are known for being extremely stable but the situation here has me concerned about stability/dropouts in the near future when moving to the newer driver kit.

I haven't tried the newest DK driver (1.08), no time yet...

The ADI-2 Pro does not have any (Mac) driver, so if there is an issue it must be something else.

I'm aware my setup is "a bit unofficial" being a Mac Pro 5,1(2012) with a current version of Monterey installed(via OpenCore), but i'd like to report that software playback doesn't seem to work with a 1.08 driver and my AIO, maybe because the card is recognised as a thunderbolt device and my Mac isn't really compatible with it. I can reroute the signal via built-in SPDIF out and into the AIO and it seems to work fine, but can't find a way to make software playback work. Anyway, i'm back to the kext driver and everything is fine. Not sure it's even worth investigating since installing newer versions of MacOS or even Ventura on such old hardware that is no longer supported officially by Apple is already bit of a hassle and kinda pointless, but reporting my findings nonetheless.

I just tried the DriverKit driver (1.08) on my iMac 2019, running macOS Monterey 12.6.6. The CPU usage was much higher than the kernel driver and I got a ton of pops and glitches, both in Logic Pro X and also in Safari playing YouTube videos e t c.

The kernel driver is rock solid for me and I've never had any glitches of any kind. Maybe this was specific to my system but the driver kit was completely unusable for me.

I'm running my HDSP RayDat inside a Akitio Node duo thunderbolt enclosure. Possibly that has an affect on the stability of the driver.

Well, the day is here. I just ordered a new M2 Mac Pro so I can put both of my HDSPe AES cards in it, and my AIO Pro along with a few other things.

I'd love to see or hear an official update from RME on what's going on with the DriverKit driver as we are at a point where the older driver may stop working in MacOS.

Good stuff, maybe you can try one of those tests I did before also?

Thanks for the report. Next week brings an update for the HDSPe DK driver and firmware which solves a potential cause of clicks while TM FX is open.

Great!

Looks like Apple has more issues than the one already acknowledged:

So far, I can trigger an audio disruption if I am playing audio and then I open another DAW that uses the same audio device.

For example, I'm playing audio in REAPER via my first AES card, but I open iZotope RX which is set to use the same AES card and main output channels, I hear a slight disruption in audio.

My other AES card is exclusively for WaveLab use and if I open WaveLab while audio is playing in REAPER (using the other AES card), there is no disruption to what I'm listening to in REAPER on the main AES card.

My AIO Pro card is mainly used of Qobuz playback and same deal, if I am playing audio in REAPER and open Qobuz, there is no disruption in REAPER.

I also do a lot of multitasking while dialing things in (before I actually record back in to REAPER) and none of those actions such as checking email. surfing the web, navigating the Finder, etc. appear to be triggering a dropout is far.

It seems that maybe only actions in apps that share the same AES card could cause a little disruption.

I've been noticing this on my mobile setup a bit when using Sonnox ListenHub so at this time, it feels like more of an Apple thing than RME. My mobile setup involves no PCIe cards, just an RME ADI-2 Pro FS but the issue also happens if I'm my super mobile Grace m900.

When I can trigger the disruption, it's not a big clicky dropout, it's more like subtle skipping sound.

I just tried quickly opening a ton of apps while REAPER was in input monitoring of my mastering chain, as if I were dialing in a song or recording back to a new track.

I opened Apple Music and Spotify which are set to play to may Mac output (currently set to Grace m908 via USB), Qobuz (set to my AIO Pro Card), as well as WaveLab which is set to my other AES card.

I didn't hear any dropouts. I even looped a 1k test tone so it would be more obvious to hear something.

The only thing I can reliably reproduce right now is that if REAPER is playing/recording audio, and I open iZotope RX which is set to use the same AES card/outputs, then I get a fairly subtle skip/disruption but nothing crazy.

Not ideal but so far that's the only thing I can trigger.

Hi
I use the HDSPe raydat rev 1.0 in a mac early 2008 with a montery os. Stil no luck in getting Logic connect in the recording modus. I can select the raydat in logic. Sometimes there is this high pitch tone, it seems to be connected, then I quite logic and the sound is gone... Is this a sign that the card is broken? It's connected in a proper way. I have the same screens as shown below....I'm running-out of options :-)
Anyone recognize this problem? Or is it the midi audio set up in the mac?
Kind regards Mireille

I've used the HDSPe series DK driver 1.07
