Seen here I can then change the setting from digilink to internal and get my system audio back online. Not a major issue as I work in 48K mainly. Still would like to understand why this is happening. The only use for Dante is mac system audio, and Im running 1 AM2 as a headphone amplifier on my cue send. Currently everything is connected directly to the trash can.

If the sample rate moves from 48K to other setting, its quite a pain to get the AM2 back online. Dante Controller sync tab

I haven't really battle tested the system at 48k but just hitting record on a mono track and letting it run for about 3 minutes produced an sync error and aborted recording so even with your suggested settings it seemed quite unstable. I saw another user at gearslutz say he had some weird issues that were hard to chase and ended up replacing the dante card which solved them.

In your opinion What is the most stable way to run a MTRX with s6? Is a external clock the best case? I assumed with just one I/O device clocking internally would be fine for stability. Again thanks for your help on this.
You have set the MTRX to follow the sample rate of the HDX card in your MAC. The sample rate of the HDX is set by Pro Tools when you open a session. However, when you close Pro Tools, Coreaudio takes over the control of the HDX card, including setting of the sample rate. So if Coreaudio is set to a sample rate of 192 kHz, the MTRX will follow that and also be set to 192 kHz. In order to prevent that, you must set the Coreaudio sample rate to 48 kHz.
