Core 256 Dante – Mac Os Ventura – Clock instability

[Michel Gallone]

Hello,

I have issues with clocking.
The DAD Core 256 Thunderbolt audio interface often goes out of sync (audio dropouts, sync alarm on the Dante sound card) when operating as a Thunderbolt Audio Unit sound card with the Mac Studio.

It happens often when outputting sound from the Google Chrome app, but it also happens when used as a sound card for AVID Pro Tools.

It makes the entire system quite unreliable.

Do you have any idea why the audio unit driver for the Core 256 is that unstable?

Thanks for your help.

Hi Michel,

Apologies for the delayed answer – We’ve had a few supporters be ill for a while. The cold Danish weather can be cruel.

I’ve looked through your description and I can’t find that there should be any issues within the Core256 hardware in what you’re experiencing.

I am immediately suspecting Dante sync issues and I would need some more information on how you’ve configured your studio setup to help you properly.

So, if you can write to support@ntp.dk with some detailed diagram on your setup (just to understand your configuration) and perhaps screenshot the different configuration pages in your DADMan page for the C256, I’ll be able to dive into it.

Let’s get you rolling again!

Hello
Update on the clocking issue on OS X, Ventura 13.7.5 (22H527) and Core-256.
After some research, it appears that 2 audio drivers that are installed automatically with the accompanying application are problematic and cause clockinhk issues, audio drop outs:
-> Teams Audio Driver
-> Teamviewer Audio Driver

I remember, a while back (4-5 years ago), discovering that they were problematic with most professional audio Mac drivers.
It seems they are still creating issues today. So you have to remove them (in OS X Library) still to this day.
I haven’t experienced clock issues since then. Hopefully, that was the only issue.
