Protools wont play due to -22005 error

[MirkoP]

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!

Greetings,

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

best,

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.
