Default Protools wont play due to -22005 error

Hi everyone,
I just switched systems by installing my Native PCIe Sync HD and HD I/O on a Mac Studio M2 Ultra with OS 13.6.4, Sonnet Echo III, and Pro Tools version 2023.12.1.
Immediately after installation, I had a series of playback issues with a 9129 error.
I tried changing the Playback Engine to "built-in" and it seemed to work fine.
I tried changing the connections between the Sync HD and HD I/O by putting them in loop sync and at one point it started working again. Suddenly, however, the problems returned.
The error message now is -22005.
I have tried all the solutions I found on the internet but nothing seems to work.
Has anyone had a similar problem and knows how to fix it?
Please Help
Thanks a lot!

Does your TB3 chassis have a toggle switch ->
Move Gen 3/Gen 2 (HDX) switch to the Gen 2 (HDX) position to enable

Hi Mirko! I'm getting the same thing (not your first error but the -22005 one quite frequently too since moving to a 14,8 Mac. And it's gotten worse since 24.3 Here's a related issue with the same error involved. And I don't run a chassis. Under 23.12.x it happened about once every 2-3 weeks. Now it's pretty much every morning. A friend is running an identical hardware setup as me and is getting the exact same error.
I usually get it after first turning on my rig in the morning. I then have the reboot the machine once or twice and then it works and is stable for the rest of the day.


PTHDn 2024.3 (OSX13.6.5), 8x8x8, MacPro 14,8, AJA LHi, SYNC HD, all genlocked via AJA GEN10, 64GB RAM, Xilica Neutrino, Meyersound Acheron
